Boat Blister Repairs, Large Size! Indepth Boating Here ph


Seeing your boat with boat blisters are bad enough, but having a large boat blister sometimes makes you feel devastated. I have seen some boats with a few, but large boat blisters that seriously go deep into the laminate (fiberglass). All you can think about is the cost of repair and/or the impact on the value of your boat or yacht. It does not matter if you have a powerboat or a sailboat, which means a boat going fast or slow has no influence on the formation of blisters. You can look up my other articles on EzineArticles about: Boat Bottom Blister Repairs to find out some of the reasons you get these. Even with the large boat blisters, the repair is easy enough. Mainly you need only drying time to allow the moisture to get out of the laminate. Let’s see how we can make this repair… If your boat or yacht is in the northern states and has been out of the water for the winter season, that’s great. You’ve had the drying time by being out of the water all those months, only if you completely opened the boat blister up. If you did not, open it up now and let it drain. On boats that have just come out of the water, do the same…open up the boat blister completely. Don’t worry about being neat about it, get it open and take any loose material out of there, and again let it drain. Give it a day or two of draining and use some acetone to clean it up. It might look scary at this point, but don’t worry, everything will be alright…just let it drain. Keep cutting/grinding away the loose material. You want to end up with sort of an elongated soup bowl. Small opening in the bottom and widens out as you come to the boat bottoms’ original surface. A 6 or 8 to one ratio is fine, but you may need more considering if the damage to the laminate is be wider. You want to start building your layers of fiberglass (laminate) from the bottom up. I can’t stress enough about having it dried out completely, and you can accelerate this process by using heat lamps or floodlights. You don’t want to have the area too warm/hot that you’re drying, just really warm to the touch. Read all instructions and cautions on everything you use. Once dry, clean with acetone and take your grinder with about 36 grit and do a final shaping. It does not have to be absolutely perfect, just make it like that soup bowl, and you’ll be fine. If hairs of fiberglass are evident, that’s just fine also…again wipe it down with acetone, and let’s get ready to continue the repair. To get ready, cut circles of fiberglass chopped strand mat to match the bottom flat area, and make them larger and larger overlapping the previous layer and going on to the existing fiberglass/laminate of the boat. On the last few layers you want to use fiberglass mat, even alternating the two different types. You should use a laminating roller to make sure all the air bubbles come out once you start with the fiberglass resin and the fiberglass. If your boat blister


area is really deep, you may want to do part of the repair one day and do the rest the next day. This is just in-case the laminate starts to sag from all the weight of the fiberglass/laminate layers and resin. The following day continue the procedure, but first start by grinding the area up again, and clean it up with acetone. Now mix your fiberglass resin with the hardener (read all instructions and cautions on labels of everything you use), make sure the very bottom is roughed up, apply the resin and the first cut-out of fiberglass you made. Squeeze out all air bubbles and proceed. Turn the fiberglass cloth you are using in different directions so the pattern is different from the one below. Remember to use the laminate roller to get out the air bubbles which are your enemy! As you build up the last few fiberglass layers, they should be just about on top of the original fiberglass surface. Again, the last few layers should right there on the original surface…and that’s about it. Once hardened, you may want to use some filler to take out any dips or variations on your final surface. Put on barrier coats over the final surface to protect your repair from any moisture, and put on your boat bottom paint. That wasn’t that hard… There are many ways to repair boat blisters, and for more information on Boat Blisters, you can surf the net or just call or email one of the many service/product companies. By repairing your fiberglass boat blisters on your used boat or used yacht, helps strengthen your boat and brings more value to it, whether you have a used powerboat or used sailboat. And Why Knot!
