Apply paint gradually if using a roller.
Air bubble roller popper for floor coatings.
For example moisture cured urethane mcu coatings that dry and cure by reaction with atmospheric moisture and other coating types i e aliphatic polyurethanes that are formulated with moisture sensitive components can also bubble.
Eliminate any source of direct air blowing onto the surface.
Follow directions for mixing and using primer.
Allow the coating to dry thoroughly then sand the coating smooth and repaint.
Little pinholes in the floor.
Using a roller to pick out the bubbles from the floor.
Air moving in and out of the concrete slab with changes in temperature and barometric pressure.
Concrete that has not been cured properly and is soft punky.
Another common reason for air bubbles in your floor coating is dry rolling the product.
Use this technique for removing air bubbl.
If bubbles are seen while applying the primer a metal porcupine roller can be used to pop the surface tension as bubbles start to develop.
Use a primer system on all porous concrete.
Rapid stirring for a prolonged period can introduce air bubbles into the paint that might persist in the dried paint coat.
After applying coatings with a squeegee you should never take a dry roller cover and roll out the floor.
If there is a very noticeable amount of air bubbles during application try slowing down application speed.
This is wrong repairing bubbles once cured is very difficult or nearly impossible without needing to re coat.
If outgassing bubbles are seen during the primer application a metal porcupine roller can be used to pop the surface tension as bubbles start to develop.
Some people mistakenly assume that they appear later once the floor has cured.
Always use a jiffy mixer and medium to slow speeds.
Woven shed resistant rollers are recommended.
Aides in flow out and leveling.
If air bubbles are present in coating allow to sit briefly before pouring on the floor.
Always follow recommended nap and type of cover.
Follow label and data page directions for the appropriate applicator.
Bubbles sometimes form within the coating or on the backside of the coating film.
These pinholes are caused by air bubbles formed in the epoxy coating during the application process.
Avoid aggressive shot blasting.
Fixes during prime coat installation.
This can often prevent the outgassing bubble from forming and allow the primer to fill in the pinhole that would otherwise be created.
Various nap roller covers have air within them.
We recommend saturating your 9 or 18 roller cover in the product and then rolling it and make it.
If you see bubbles forming in.
Effectively remove air bubbles from an epoxy coating using acetone spray technique.
