Paint Questions

Ok lead in: I know this is a stupid question I just am second guessing myself.

When mixing 2 part paints and the directions say thin by 10% volume, what does this mean?

If you're making 10 ounces of paint, add two additional ounces of thinning agent, total amount = 12 ounces

Makes the paint thinner so it soaks into pores of wood and other porous materials, gives a good bond for the next coat.

Most auto body supply vendors/supply stores sell sell mixing sticks & cups with many different mixing ratios & % on the stick or cup.

Fitst Team ....... 10% of 10oz would be just 1 additional ounce not 2 ounces. Although I am not going to enter a discussion on the differences between mass and volume ........

So Tuna ..... just mix 5oz of part A with 5oz of part B then add 1 oz of thinner. But if you want to follow the directions, lets keep everything in volume......... so add 250mL of part A with 250mL of Part B for a total volume of 500mL then add 10% of thinner or an additional 50mL. Mix everything up really well.

The thinner allows the paint to "flow" easily off the brush and eliminates any brush marks as the paint dries.

Tuna,even if its not a two part paint... the thinner on 10 oz of paint is 1oz

You're right, that will teach me to multi-task
At least I didn't have a typo

Thanks guys. That's where I was for mixing. It's flowing out And leveling unreal. I'm very happy with it. It's drying to the touch no problem just not super hard yet. I have a few down days now so it should be fine when I get back to it.

You will need at least 2 coats Tuna.

Definitely doing two coats. There are very few imperfections amazingly but I still need to sand. I was thinking it might not sand well until it was harder. Just moved it inside for the night and today being low 70s really helped.

Will wet sanding be better between coats for some lubrication?

No Tuna .... just light hand-sand with 320 grit. No need to wet sand. Just take the "gloss" off the 1st coat, remove all the dust and then hit it with a 2nd coat.
