Substrate preparation

Substrate preparation

Depending on substrate:

Depending on substrate:

• • • •

• • • • •

Removal of old flooring materials.

Improvement of defective substrates where applicable.

Cleaning (blasting, grinding, suction cleaning).

Application of necessary joints in the case of merged structures.

Application of height marks.

The substrate must be cleaned with a broom, vacuum cleaned and subsequently primed with weber.floor 4716 primer (mixing ratio: 1:3 primer/water).

Removal of old flooring materials.

Improvement of defective substrates where applicable.

Substrate preparation (milling, shot blasting, grinding, vacuum cleaning).

Adoption of existing joints:- Limitation of liability if joints are covered and have not been carried over in the upper layer, as there is the danger of cracking during use.

• Application of height marks.

Priming Apply two coats of weber.floor 4716 primer dispersion diluted 1:3 and 1:3 (concentrated primer; clean water) on to the substrate (concrete or cement screed).

NOTE: Some substrates might require more priming due to their porosity.

If so prime first time with 1:5, for example. The primer must be brushed on to the cleaned substrate avoiding ponding.

Reinforcement (if required) NOTE: If doubts exist regarding substrate strength, for example, substrate pull-off strength < 1.5 N/mm² (MPa), ALWAYS reinforce the base material using a bolted down steel reinforcement mesh.

A steel reinforcement mesh Ø 4mm, mesh 150mm should be bolted down on the substrate using a nail gun tool.

1. Place a steel reinforcement mesh Ø 4mm, mesh 150mm on the substrate.

Place a second mesh directly over the first mesh ensuring the steel rods are aligned to avoid overlapping. If necessary, trim off steel rods at the ends.

weber.floor 4716 primer

2. Bolt each mesh down with 4-6 bolts. Use a perforated strip, approximately 5-10cm, to attach each steel reinforcement mesh to the next at the adjoining corner. Ensure each mesh is properly bolted down. The mesh should not rise up when walked on or during application of the selflevelling material. Wrap the perforated strip around the steel rods and bolt down. If not using a perforated strip, always attach the bolt together with a washer in order to keep the mesh bolted down.

Base layer (if required) Filling local cavities • Level out defective areas, such as holes and imperfections up to a depth of 50mm, with weber.floor 4040 combi rapid.

• After approximately three hours, subsequent work may continue.

Reinforcement If required, apply weber.floor 4945 glass fibre mesh to the existing substrate. weber.floor 4945 glass fibre mesh is placed on top of the substrate or on top of the floating layer, for example, PE-foil, geotextile, sound insulation etc, with an overlap of at least 50mm. If used on a geotextile, weber.floor 4945 glass fibre mesh should be laid in the same direction as the geotextile in order to minimise the risk of the floor compound leaking through. When weber.floor 4945 glass fibre mesh is applied on sound insulation, it is recommended that both ends of the mesh be fastened to the insulation/ substrate with hot-melt adhesive.

For more information, please visit www.netweber.co.uk

If the substrate is very rough and uneven, it requires a base layer. Use weber.floor 4600 industry base pumped on to the substrate to the required thickness in sections 6-8m wide. When filling the sections be sure to advance in strips, adding each new strip to the old as quickly as possible, so the material can merge. Afterwards, level out the surface while it is still fresh, using a notched trowel. Follow the product data sheet.

NOTE: Always pump the products with a continuous mixer pump. The volume of added water must be specified on the continuous mixer. Check the correct volume of water to be added before and after application (see Product Data Sheet).

20

Priming of base layer

Additional recommendations

1. Apply two coats of weber.floor 4716 primer dispersion diluted 1:3 (concentrated primer; clean water) to weber.floor 4600 industry base.

2. Apply the first primer coat as soon as the base layer can be walked on and the second coat as soon as the first coat is absorbed.

3. The aim of applying the primer is to achieve a thin but tight membrane.

4. Use a brush to apply the primer and also to remove any excess primer material from the surface.

5. When the primer has formed a film on the surface, commonly after 2-4 hours, the top layer weber.floor 4655 industry flow rapid or weber.floor 4610 industry top can be applied.

To ensure a straight joint between the sections, we recommend first pumping the material (weber.floor 4610 industry top, weber.floor 4650 design colour) into every second section (for example first, second...). Then removing the foam barriers and masking the two edges of the middle section with masking tape (minimum width 50mm) 6 hours after pumping at the earliest.

Immediately after, pump the material into the remaining sections. Remove the masking tape after approximately 30 minutes.

Top layer

weber.floor 4610 industry top is pumped on to the substrate to the required thickness, normally 8-10mm, in sections of approximately 6-15m wide. When filling the sections, advance in strips so that each new strip is added to the next as quickly as possible to enable the compound to merge.

Afterwards, level out the surface while it is still fresh, using a notched trowel.

Pump weber.floor 4655 industry flow rapid on to the base to the required thickness in sections of approximately 6-15m wide. When filling the sections, advance in strips so that each new strip is added to the next as quickly as possible to enable the compound to merge. Next, level out the surface while it is still fresh using a notched trowel. Interruptions to the work process must be avoided. Do not mix different batches for areas that are connected.

NOTE: Always pump the products with a continuous mixer pump. The volume of added water must be specified on the continuous mixer. The accuracy of volume of water added must be checked before and after the mixing process (see Product Data Sheet).

For more information, please visit www.netweber.co.uk

Further recommendations • Air dehumidifiers, draughts and too high temperatures must be avoided.

• weber.floor 4600 industry base, weber.floor 4610 industry top and weber.floor 4655 industry flow rapid are cement-based materials that may be used immediately. As a result, the shade of the hardened flooring surface may vary with use of different raw materials. Slight variations in colour may occur during the laying process due to, for example, fluctuations in the volumes of water added or surface processing.

• When impacted by dirt or liquid agents, the surface reacts like a dense concrete surface.

• Movement and expansion joints must be carried through from the substrate.

• In the case of industrial use, dummy joints may develop into spontaneous joints. When overlaying the dummy joints, cracks may occur.

• Cracks may occur due to the consistency of the substrate and if layer thicknesses are exceeded.

• Small hairline cracks may occur due to the building shape or the substrate.

These are purely optical flaws and have no influence on the floor’s adhesion or loading capacity.

• Early point loads during the first week may leave small indentures since the material is still in the process of curing.

• Rapid reconstruction of stores with cement-bonded floor coatings as final flooring material - for internal use.

• Total reconstruction time: Minimum 48 hours.

dB Floor

Surface slabs

Preparation Substrate preparation - depending on substrate: • Improvement of defective substrates where applicable.

• Removal of loose material and basic cleaning of the substrate.

• Rough levelling and improvement of defective substrates where applicable.

Clean substrate with a broom; all dust and debris should be vacuumed from the surface. Smaller holes and height differences can be smoothed with weber.floor 4040 combi rapid.

Sound insulation boards

Should a cement-based material be used, weber.floor 4945 glass fibre mesh must be laid out on the surface. When laying out the mesh, ensure that the edges overlap by 50mm. If a calcium sulphate screed is used, no reinforcement mesh is needed.

As a load and heat distribution layer, five different self-levelling screeds can be used within the dB-Floor Concept:

There are many different impact sound insulation boards on the market with many different properties. Weber recommends weber.floor 4955 dB mat.

The main property to look for is dynamic stiffness. The lower the dynamic stiffness, the better the sound-reducing effect.

However, too soft or thick insulation boards might indeed have a very low dynamic stiffness but are too soft to support the floor or provide the required point load capacity.

The impact soundboards are laid on the levelled floor and cut to adjust to special room geometries.

Dividing layer and soft strips

weber.floor 4360 base flow rapid (self-drying) economical fibre-reinforced cementitious base screeds designed for floating floors up to 80mm thickness.

The minimum thickness is 25mm offering a sufficient point load capacity and a good sound reduction at moderate costs. If PVC or linoleum will be used, grinding and manual smoothing will be needed. weber.floor 4310 fibre flow (normal drying) or weber.floor 4320 fibre flow rapid (self-drying) fibre-reinforced, flexible cementitious screeds with a high polymer content. Recommended if PVC or linoleum is to be used and when you want to avoid a separate manual smoothing application (light grinding is still recommended due to the high fibre content). The minimum thickness is 25mm but it can be pumped up to 50mm.

Further recommendations The floor covering may be applied once the drying conditions are suitable.

The indications referring to the readiness for covering apply to a dry substrate, a room air temperature of 20°C and a relative humidity of 50%. Air dehumidifiers, draughts and too high temperatures must be avoided.

Normal apartments can usually be done without any joints. In the case of unfavourable geometry (narrow long corridors or big areas where the uniform slab is “cut” by partitions), we recommend creating a “dummy joint” by cutting the slab approximately 5mm deep at such critical places. If the slab is to crack, it will crack in a controlled manner at these places but it will still be held together by weber.floor 4945 glass fibre mesh. If the floor covering requires a seamless and crack-free floor, these dummy joints can be injected as soon as the shrinkage stresses have ceased, i.e. when the screed material has dried out completely!

Dilatation joints in the building do not necessarily have to be adopted as this surface slab floats complete freely, independently of the building’s dilatation joints. On the contrary, we can offer a seamless floating screed floors that also enable the tiling of large areas without joints and cracks.

Soft strips (e.g. weber.floor 4960) should be installed on all rising building structures and penetrating pipework. To form a tight mould for pumping, apply a dividing layer, like for example weber.floor 4940 Geotextile, plastic membrane or waxed paper on top of the sound insulation material.

Please note that small hair cracks may occur due to the building shape or the substrate. These are purely optical flaws and have no influence on the floor’s adhesion or loading capacity.

Under-Floor Heating Preparation Substrate preparation - depending on substrate: • Cleaning.

• Rough levelling of the substrate for installing the system plates or optional additional installation layer EPS-plates.

Surface slab Before the surface slabs are installed, weber.floor 4945 glass fibre mesh must be laid out in preparation for a cement-based screed. When laying out the mesh, ensure that the edges overlap by 50mm. If a calcium sulphate screed is used, no reinforcement mesh is needed.

The surface in general has to be dry and free from surface contamination and other impurities. All dust and debris should be vacuumed from the surface.

Smaller holes and floor irregularities, such as prefabricated elements and height differences, can be smoothed out with bagged sand to ensure the stable application of the heating plates.

Optional installation layer This optional layer can be used for sewers, water pipes, electrical installations or any other requirement for an intermediate layer.

Small installation needs are conveniently dealt with using a 30-50mm layer of EPS boards into which ‘omega shaped’ grooves are cut with a heat cutter.

Where there are several pipes, it is more convenient to make a complete duct and to tie down the group of pipes. The gap is filled with thick flowing mortar or screed to form a uniform support for the system plates.

Pipes can also be drilled down through intermediate slabs and be led in the suspended ceiling below or through self-bearing base floors.

Heating pipes

As a load and heat distribution layer, three different self levelling screeds can be used within the Comfort Floor Concept: weber.floor 4360 base flow rapid- An economical fibre reinforced cementitious base screed, designed for floating floors up to 80mm thickness.

The minimum thickness is 25mm offering a sufficient point load capacity and a good sound reduction at moderate costs. If PVC or linoleum is to be used, grinding and manual smoothing will be needed. weber.floor 4310 fibre flow or weber.floor 4320 fibre flow rapid- A fibre reinforced, flexible cementitious screed with high polymer content.

Recommended if PVC or linoleum is used and when separate hand smoothing needs to be avoided (light grinding is still recommended due to the high fibre content). The minimum thickness is 25mm and the maximum thickness is 50mm.

Heating pipes made of PEX or composite materials are common. To achieve a high efficiency at the windows, start the heat circuits at the perimeter walls.

The areas close to the central heating and at pipe joints should be fixed to corner plates.

The ingoing water is usually 23-30°C and the returning water cools down approx. 1-4°C. The heating designer calculates these temperatures and the ingoing water temperature is usually adjusted with an outdoor thermostat, whereas the circulation per room is regulated by room thermostats.

The length of the pipe circuits, the pump’s pressure, the room area and the used floor covering material also affect these temperatures. Therefore, the heating design is carried out by professional heating designers.

Dividing layer Geotextile separates the fresh screed from the heating system below and stops the screed flowing in between the insulation boards. Geotextile is carefully selected for its resistance to leaks and its workability guaranteeing a rapid and secure final result. The Geotextile is rolled out on to the plates.

Connecting parts are taped and the dividing layer is applied to all vertical construction elements. This ensures that materials added subsequently cannot run behind them.

All materials are pumped directly on to the Geotextile in the recommended thickness and are levelled by wobbling the fresh screed.

NOTE: Pure Portland cement-based screeds or concrete are not suitable for the Weber Comfort Floor, due to the aluminium reacting (vaporising) with the high pH of the humid concrete!

Further recommendations The floor covering may be applied once the drying conditions are suitable.

The indications referring to the readiness for covering apply to a dry substrate, a room air temperature of 20°C and a relative humidity of 50%. Air dehumidifiers, draughts and too high temperatures must be avoided.

Normal apartments can usually be done without any joints. In the case of unfavourable geometry (narrow long corridors or big areas where the uniform slab is “cut” by partitions), we recommend creating a “dummy joint” by cutting the slab approximately 5mm deep at such critical places. If the slab is to crack, it will crack in a controlled manner at these places but it will still be held together by weber.floor 4945 glass fibre mesh . If the floor covering requires a joint, and a crack-free floor is required, these dummy joints can be injected as soon as the shrinkage stresses have ceased, i.e. when the screed material has dried out completely!

As the heating pipes are completely below the screed slab, the risk of damaging these when cutting the dummy joints is very small. Also, the heat pipes will not suffer from the screed slab having any joints as they are not embedded in the screed.

Case Studies Client: Envisage Group Products: weber.floor 4716 primer & weber.floor 4655 industry flow rapid Contractor/ Applicator: Zenith Polar Flooring Services A striking new studio complex has been built in Coventry to meet the advanced engineering standards required of the up-market automotive manufacturers, private yacht builders and jet aircraft designers. Home to the Envisage Group, this new facility required perfectly level floors to match the precisely positioned chassis bed-plates installed to carry the car, styling buck or interior trim pack.

The three main studio areas amount to 650m² of floor space. The surface was initially treated with a brushed coat application of weber.floor 4716 primer.

This is a styrene acrylate dispersion primer that bonds into the existing flooring substrate to enhance the bond of the rapid drying screed which follows.

The weber.floor 4655 industry flow rapid screed was then pumped to deliver full volume material as quickly as possible. This self-levelling industrial flooring screed is designed to provide a hard wearing, durable floor where traffic abrasion is highest. It is suitable as a surface layer on industrial flooring.

Application is up to ten times faster than traditional screeds and the rapid drying properties enable forklift movement or resin colour finishes to be applied with minimal downtime. weber.floor 4655 industry flow rapid is supplied as a pre-blended, dry powder for application at a thickness of between 4–15mm. The benefits of a rapid drying levelling layer make it suitable for the application of epoxy or polyurethane coatings on both new and existing concrete in new-build and refurbishment projects. It can be used to level and smooth a wide range of substrates including in-situ and pre-cast concrete.

Project: Strood Academy, Medway, Kent Product: weber.floor 4150 fine flow Contractors: BAM Construction & The Progressive Group weber.floor 4150 fine flow commercial screed was installed at the £29 million Strood Academy, a new secondary school in Medway, Kent. The project included a new sixth form block and vocational centre. Over 150 tonnes of weber.floor 4150 fine flow was installed achieving an economical solution for this large application area of over 13,000m². weber.floor 4150 fine flow is a standard drying, cement based screed for levelling and smoothing concrete substrates. It can be applied at thicknesses from 4-30mm and is ready for foot traffic in 2-4 hours allowing fast and convenient access for other trades. It is ready to receive a final floor covering in 1-3 weeks following installation.

Case Studies Client: Woolley GMC Engineering, Coventry Products: weber.floor 4716 primer & weber.floor 4655 industry flow rapid Contractor/ Applicator: Zenith Polar Flooring Services

Weber’s industrial and commercial flooring products, designed for speed of application and premium performance, were used in a major renovation project at Woolley GMC Engineering in Coventry. This British engineering company’s trading success required a rapid factory facility renovation. weber.floor 4655 industry flow rapid industrial screed was specified and was responsible for the ultra-fast recovery of the flooring and the creation of a hardwearing safety roadway for fork lift truck operations.

Paul Sant of Zenith Polar Flooring Services was quickly able to determine that use of weber.floor products would deliver the required result. “Clearing damaged surfaces takes hard work and time but thorough preparation is essential for a successful finish. A coat of weber.floor 4716 primer was used to seal the base before we applied the weber.floor 4655 industry flow rapid screed for the safety roadway. This is a rapid drying screed and resin base that can take foot traffic in one to two hours and the final epoxy sealer within 24 hours,” reported Paul. weber.floor 4716 primer is a styrene acrylate dispersion primer for preparing most building substrates and is used prior to applying the weber.floor 4655 industry flow rapid screed. The Woolley Engineering facility was quickly operational, with new multi-station machining lines rapidly installed, and the 100m² of safety roadways also quickly in operation.

Case Studies Project: London Film Museum, Covent Garden Client: Capital and Counties Properties PLC (Capco) Products: weber.floor 4310 fibre flow, weber.floor 4360 base flow rapid, weber.floor 4610 industry top & weber.floor 4635 design ground stone Architect: KPF, Kohn Penderson Fox Associates International Contractor: Ellmer Construction Applicator: Neonclass High-performance products from the extensive range of Weber’s commercial and architectural flooring products have been used in the newly refurbished Flower Cellars building in London’s Covent Garden. This dramatic space has become a new cultural concept for the London Film Museum and the London home of the internationally acclaimed restaurant, Balthazar. weber.floor 4310 fibre flow levelling screed, designed for the renovation of existing floors including floating floor construction in domestic and commercial applications, was pump-applied to 1700m² of floor space covering the exhibition areas, workshops, conference centre, restaurant and bars, and the vaulted entrance to the cloakroom facilities. Two coats of resin primer and aggregate blind broadcast were then topped with weber.floor 4635 design ground stone to achieve a striking, long-lasting and low-maintenance result.

The remaining 800m² floor space of service corridors and plant rooms, were all pumped and installed with weber.floor 4360 base flow rapid. This fastdrying, fibre-modified base screed was then topped with a hard-wearing finish of weber.floor 4610 industry top industrial screed, and then sealed.

Project: Heathrow Airport Terminal 5 Tunnels Client: BAA Ltd Product: weber.floor 4610 industry top Architects: Pascall + Watson Contractor: Carillion Applicator: The Progressive Group The high-specification and robust industrial flooring screed weber.floor 4610 industry top was specified in the construction of below-ground access and service tunnels at Heathrow Airport Terminal 5 to create a durable, attractive and very hard-wearing surface.

The main terminal is constructed over eight storeys-five above ground and three below-and is served by two satellite buildings: Terminal 5B and Terminal 5C. Two air-side access tunnels, which are both over 400 metres long and 8 metres wide, connect the new Satellite B and Satellite C buildings and go onward to the main T5A terminal. Their primary use is for the vehicular transport of disabled passengers and the movement of baggage between buildings. weber.floor 4610 industry top is a standard drying screed and can be applied in thicknesses of 4-15mm and has high compressive and flexural strength. weber.floor 4610 industry top can take foot traffic within 2-4 hours of application and is fully cured after 7 days.

Client: John McAslan & Partners, Euston, London Product: weber.floor 4650 design colour Contractor/ Applicator: Creation Flooring

The renovation of floors in a high-traffic reception and meeting place was carried out using weber.floor 4650 design colour screed. weber.floor 4650 design colour is a pumpable material, rapid-hardening and selflevelling screed compound used widely in retail stores, shop aisles, shopping centres, store rooms and light industry, and is available in 10 colours. In this project, dark grey was selected.

Here, the concrete substrate was in a poor condition with significant cracks and fissures. The client wanted to create a modern, contemporary ‘chic’ appearance, which would both remedy the damage and create the visual impact they required. weber.floor 4650 design colour was specified, a self-smoothing, through-coloured, low-maintenance, light industrial floor compound as an alternative to the specified polished concrete.
