Deck Paint

[Culinary411]

Ok guys....
Please tell me about polyurethane deck paint. I've read everything I can get my hands on and I think I'm ready to start. I'm still deciding if I should go with a single type paint or a two part. I know that the two part is better, but how is the sanding different? How far down do I have to sand to do a two part? Right now its just original factory deck finish from '76 on fiberglass.
I've read that two part paint needs a better sanding job, but how much better? Is it do-able by the amature? I know I can tape it off and do an awesome paint job but I'm not so sure about the sanding and prep part. I've never done it before. Any and all advice is greatly appreciated.

The maker of the coating you decide to use will have details on what is required. I would use the 2-part as it is more durable and the prep is the hardest part on either 1 or 2 part.

If you're going to use a two-part LPU paint and you'll probably be rolling and tipping... I would highly recommend practicing a bit on something a bit smaller than your boat...

Preparation is very critical...especially making sure the surface is clean of all residue and oil. The two-part is more durable and has a slightly better appearance IMHO.

I have a lot of experience painting with a roller and taping off. I'm sure once I get the feel for the viscosity of the paint I can make it look great. I'm just worried about getting the prep right. I'm kinda thinking I'll wash with a detergent, then sand it down to fiberglass or almost fiberglass whatever the paint manufacturer states, then, powerwash and scrub with detergent again and let dry for a few days before painting.

Detergent residue may effect bonding with the new paint. Use the paint manufacturers recommended solvent for surface prep.
