Bought a board in need of somw delamination repair. I have done general dings on top/bottom and rails. Never a delamination. Looked on You Tube and different sites to try to get a good video but did not find any that addressed my repair. I removed a section of glass down to the foam. Need some step by steps to repair from the old foam up. I bought both laminating and sanding resin. Also cloth. I think 6 oz. maybe 4 oz. Any how, any help and or sites with vids would be great.
You should have bought a blank instead…

Welcome to Swaylocks! My general procedure for de-lam is to remove the de-lammed glass, and re-glass the raw foam. Looks like you got that much figured out. Glassing is pretty standard practise on a de-lam: lam coat, hot coat, gloss coat, sand between coats. Kinda like a ding repair but bigger, I guess. Any threads on the subject (glassing) here at Swaylocks, or any videos showing the glassing process, would likely apply. Glassing is such a broad topic...was there a specific question?
The only other thing I would add is to see if the foam under the delam needs to be built up. I’ve done a few and in each case the foam under the delam had taken on a “dent”. I used microballoons mixed with resin to build up the section to make sure it was flush with the rest of the deck and then go through the glassing process.
The repair is visible due to the color of the filler/resin mix but they held up fine over time.
Thanks for the help. My major question is Do I need to repair/build up the foam under the delam section. While it is not new, it is not too bad.Not sure if you can tell by the photos. Another kind reply stated something about " micro beeds" or something. Mixing it with resin and leveling it out. Is it best to take a straight edge off the stringer and "float " the foam, or should I lay the new cloth on the old foam.Just wondering how the deck will look with the new cloth on it. Also, I was wondering how many layers I should put on the deck. Do you apply the lam. resin, sand, sanding resin, sand and then the final coat. Also, what is the “hot” coat as it is known? Thanks,Dave.
ok so if the foam is all soft then you should route it out and put a new peace of foam there and level out or you can use micro ballons to fill in the gaps
i would never take down the stringer, you gerneraly want to keep the board as origanl as possible, its better to lay down new foam and reshape or fill with micro ballons and reshape
if the foam is ok and you reglass as is it will look like what ever the foam looks like
i would use 2 layers of 6 oz cloth with lam resin then hot coat
the hoat coat is the layer of resin you apply after you lamanate, hoat coat resin has surfaceing ageant added to it so it will be sandable
I was thinking of giving it a go myself, but after having a local shaper look at it , he siad the stringer was cracked all the way through. He is going to lay 2 layers of 6 oz. and hope for the best. Would it do any good to “splint” the stringer. Say route out on both sidea the thickness of the board and put two support braces on the sides for extra support? Or, once the stringer is comprimised, it is what it is.
it wouldnt hurt anything to put a spint in the board but some extra cloth would help even more
Thanks again for the help.
I reinforce the stringer with roving… channel out the foam on either side, saturate some fin rope/roving, and lay it in there. Press it flush with the stringer, and glass over it. It will last a good long time.
The other thing I thought about doing, if the foam on the deck is really dented down deeply, is to glue in some PVC foam, shape it down, and glass it over.
