Pool paint calculator
Pool paint is one of the most coverage-thirsty applications: epoxy at 150 sqft/gal, chlorinated rubber at 250 sqft/gal, and two coats are non-negotiable. The math accounts for floor + walls + shallow-to-deep depth transition.
Estimates round up to the nearest quart and are based on Kompozit's published coverage. Buy slightly more for touch-ups and color changes.
Pool paint chemistry matters
Once you commit to a chemistry — epoxy, chlorinated rubber, or acrylic — you're locked in. You can't put epoxy over old chlorinated rubber, or vice versa, without complete strip and primer. Match the existing paint chemistry, or strip everything to bare substrate.
Two coats, drained pool, dry surface
The pool must be empty, fully dry (24+ hours after the last washdown), and at the right air temperature. Pool paint applied to even slightly damp concrete will blister within months.
FAQ
No — STRONG is concrete paint for above-water use. Pool paints are formulated to handle continuous immersion, chlorine attack, and UV through water. Use a dedicated pool paint.
5–7 days for epoxy, 3 days for chlorinated rubber, longer at high humidity. The paint can read "dry" on day 2 and still not be cured enough for water.
