I have some crazing on my decks…What is the best way to repair this?

We tried epoxy filler-microglop and found that due to UV deterioration, we ended up with brown spots wherever we had put it. That, plus crazing continued to spread. We ended up painting the deck and cabin four seasons ago with 2-part polyurethane (Interthane Plus), and have been happy ever after. The base primer filled in all the cracks and crazing, and we haven''t had a problem since. It IS a lot of work.

There is a book by Don Casey - Hull and Deck Repair (I think). Lots of pictures and very easy to follow. I recommend picking it up.

In a nutshell - If you have wide spaced crazing you can take a dremel tool, grind out the crack and then fill with new gelcoat (exact color match is ESSENTIAL). If your crazing is close spaced he suggests removing the entire area and putting down new gelcoat (messy and involved).

Good luck!

Interlux 4000 is a 2 part barrier coat formulated for this purpose. I applied it before using the interthane 2 part paint an am happy with the results. Call the interlux tech service.

Did you sand down your deck before applying interthane? Did you brush on or spray?

wash with soap and water, wipe down with acetone, roll and tip both the barrier coat and interthane. the nonskid is in good shape so I didn,t use anti-skid. I did use "flatener" to cut down on the gloss.

Neither, I will be starting the work in April. I just bought Don Cassy’s book on Deck repair and it seems to be a good resource. What would you recommend??? Spray or brush, etc…

Prep takes the longest time - be sure you tape or mask EVERYTHING you don''t want painted. We rolled our deck and didn''t bother tipping. With the four and six inch foam rollers (which you can get in "contractor packs" at Home Depot) the finish looked (and now, four years later) and looks fine. It''s starting to wear in a couple of spots where adjusting lines chafe on cabintop edges, but a quick touchup should only take an afternoon.
