Pool Paint cover changes a lot based on the kind of Paint and depends on whether the surface was already painted. Count the right amount before you start helps to avoid many problems and extra expense.
Water-based Pool Paint works for wet surfaces and stays color stable and strong against UV rays. It covers around 200 to 300 square feet per gallon on bare surfaces. On already painted areas that cover goes up to 300 to 400 square feet per gallon.
How Much Pool Paint You Need
That difference matters during planning of cost.
Epoxy Pool Paint works differently. Two-part epoxy paints with 1:1 mix covers 75 to 125 square feet per gallon on bare surfaces, which matches to 150 to 250 square feet per set. Over prior Paint the cover reaches 125 to 200 square feet per gallon or 250 to 400 square feet per set.
For that kind you need two coats. Other epoxy types cover 150 to 200 square feet per gallon on bare surfaces and 300 to 350 on already covered. Epoxy gives good resistance against marks, rubbing and chemical substances.
There is also heavy Pool Paint, that covers 300 square feet per gallon. It comes in white, blue and black colors, and no blending is needed. Really practical, according to me.
Paint made for concrete and plastic pools carry stabilizers, that help against color loss and protect the surface. Its cover is around 300 square feet per gallon.
Rubber Pool Paint offers another option. Rubber paints usually last two to three years. Usually Paint lives only half of the promised times of the producer, so plan for maybe only too years before the Paint starts to seem rough.
To estimate how many gallons you need, divide the cover number by the number of coats, then divide the whole surface area of the Pool by that result. Buy at least one gallon more than the counted amount is a wise idea. Running out of Paint during the work causes uneven application.
When you Paint over old coats, make sure that the prior layer is firm. Painting over weak old coats will make the new one not stick. Removing problem parts costs time, but it deserves the effort.
The weather plays a role also. Do not apply Paint under direct burning sun and avoid painting when the temperature is under 50°F or above 95°F. Expect four to five days of good weather and prepare thePaint before.
If you get more than 200 square feet of cover from some products, that can mean that the coat is too thin. That leads to faster wear and bad results.
