Pool Paint Bubbles & Blister...What Could Cause This?
by Donald
I have now painted with chlorinated rubber. It is starting to bubble/blister. What could be causing this? Thanks Donald Thanks for the question Donald I have a full page on pool paint. Here it is in case you missed it: Swimming Pool Paint I copied and pasted a paragraph right from the page: Bubbles And/Or Blisters"This is caused by improper preparation. For diy pool resurfacing, the paint must be applied to a clean dry surface. If applied too thick, if the surface is too hot, and if the pool is not cleaned properly, the pool paint might blister. The only remedy is to repaint the pool or the blistered spots." This is actually the only remedy I know of. The first coat of paint penetrates and fills the surface. This gives the coat strong surface and adhesion. Every application after that is normally 5 - 7 days. After the 2nd coat you should wait another 5 - 7 days before filling the pool. The paint might feel dry, but may not have cured properly. If the pool if filled too quickly you might get blistering, bubbles and/or peeling. If the weather is cooler or the air is humid, you might need a longer dry/cure time. Hope this helps and have a fun and safe swimming season. Robert
