Deck repair, Core repair ,, epoxy question
I have used WEST epoxy in the past. But I just did some looking on the net
and the MAS epoxy might be better for my project. I may be injecting some epoxy into my deck core. MAS epoxy is "low viscosity" Anyone know about MAS? What epoxy do you use? What about injecting into core? |

Deck repair, Core repair ,, epoxy question
Is this a core rot repair or are you just sealing things up?
If you are trying to repair rot, the epoxy may just seal in the water and rot that is already there and the problem will keep going beyond the edge of the epoxy. You've got to dig the bad stuff out and let the good core dry. -- Roger Long |

MAS epoxy is "low viscosity" Anyone know about MAS? What epoxy do you use? What about injecting into core? I've used West, Evercoat, and most recently U. S. Composites. U. S. Composites had the best price most recently and I was going on the theory that epoxy is epoxy, which may or may not be true. Additionally this most recent use was not for boat repair. U. S. Composites sells a "thin" version for layup and wetout in a number of curing speeds. That said, if you have water and rot in a balsa core laminate, I don't think injecting is a very effective cure. When I did some major core rot repair, I had to tear out the top layer and dig out the rot, replace the balsa core (should be cut on end grain and laid in like tile) tie it to the bottom layer with the epoxy, saturate the top of the balsa and bring up the top layer with woven cloth and mat. In my case there was enough rot repair to require a complete repaint (Cat Poly) after the repairs were done. The boundries of the rot are probably further than you can tell before you get in there, at least that was my case. If you don't get that water out, frost heave will split your top layer laminate even after you've injected the area. Frank |
