Repair and paint a Fiberglass deck to restore watertightness
A discussion started in 2012 but continuing through 2019April 20, 2012
Q. I own a patio home and the patio is over the Garage and is our deck.
The deck flooring is made of Fiberglass and the people who owned the house before us used a metal ice chipper to remove Ice, Not the best way to treat a fiberglass floor.
Anyway the floor has a few marks that the water gets through.
I talked to fiberglass repair companies they do this work and instead of replacing the deck floor ($5,000 to 10,000) they told me it is very easy to repair and paint it using a Fiberglass paint.
Looking at the Internet it is confusing as to what type paint to use and do the repair.
I was planning on painting the spots that need it with good fiberglass paint but don't know which to use, or what else is needed?

A. Hi John.
When you speak of painting "the spots that need it", you're not really painting, you are filling for watertightness -- and I think you should "fill" with epoxy/glass rather than with paint. Without recommending a specific brand name, I think you should get a two-part epoxy for fiberglass repairs. You can also get either a bit of fiberglass cloth or, more convenient, the fumed silica "filler" they offer to thicken up the epoxy, as plain epoxy may run through holes a bit before it hardens.
Think of it this way: if you had a leaking fiberglass boat, would you paint it or fill the dings? Good luck.

Any practical way to add pitch to garage floor?August 12, 2019
Q. Hello I am Steven. I own a condo with a fiberglass deck over the roof of my garage. Water is leaking into the garage from the deck.I have a fiberglass roof deck that has a water puddling problem. Water lays near the patio doors. Is there a way to level deck or pitch water away from the house?
