Good information. Thanks!

Why don't you ask your local hardware store, to begin with, as long as they will be your supplier? If what they recommend doesn't work, on your particular paint, perhaps they'll take it back. Ask.

Re: Solvent Testing for Two-Part Polyurethane

It sounds like everyone is confused on what the OP is asking...

1) They are not sure if their current deck paint is one or two part.

2) They are looking for a universal solvent to try and determine if the deck paint is one part.

3) They want a solvent that can be purchases at a hardware store (cheap) just to test.

4) Once they figure out what type of paint they have, they will purchase solvent from the paint manufacturer (expensive) that they choose.



Answer: Lacquer Thinner.

Answer: Lacquer Thinner.


Matt
Thank you for explaining this to us. However, lacquer thinner is a generic term. Some lacquer thinners are pure acetone but most are conglomerations of different solvents. They are not standardized & every manufacturer has their own formulation so they will each react differently to whatever they are applied to or mixed into.

This is also the suggested method by Sterling. Sterling suggest the same method, taking a cotton ball and soaking in their thinner and then taping it over the scratched spot overnight. if the paint lifts then it needs to be stripped before proceeding

Re: Solvent Testing for Two-Part Polyurethane

Boat next to me just Kiwi gripped his deck. With minimal prep it looks good. Time will tell on longevity. One note comparing his boat, done outside in the sun (temp mid 70's) to a boat done inside (little cooler, no sun) the finish is different. The outside boat is a more aggressive non-skid. The sun stopped the flow quicker.

Re: Solvent Testing for Two-Part Polyurethane

You'll have to remove that first.

The type of roller used appears to affect the texture a lot. I'd check to see what the 2 people used. If it was the same roller then it was the sun. If it was applied using different types of rollers that's probably what caused the difference.

Re: Solvent Testing for Two-Part Polyurethane

The difference was the conclusion of the two that did the work. They also talked before both jobs.

Good stuff to know, thanks. I'll tuck it into my "quiver" full of tools.

Thanks. I'm probably going the Kiwi Grip route but don't want a very rough texture.
