Hi Mike. 1-part epoxy paint is not epoxy. It’s a latex acrylic paint with 3-4% epoxy resin added to help increase adhesion and durability. I suggest reading our article here that explains the differences. What do you mean exactly about apply a sealer over it and then another coat of 1-part epoxy. What are you trying to accomplish exactly?

Hi Raman. Why are you worried about moisture? Did you moisture test? If you have moisture issues, then you need to use a special moisture vapor blocking epoxy primer. In terms of a standard primer, it needs to be epoxy that is specified as an epoxy primer. Not just a standard water-based epoxy. Epoxy primers are formulated for good penetration and adhesion, and less so for wear from traffic since they are coated over. Once and epoxy primer is applied, you need to wait approximately 10-12 hours and then apply the 100% solids epoxy directly over it. If wait longer than 24 hours, it will require deglossing and roughing up the surface first.

Hello Sagren. An epoxy coat primer (actual epoxy coating) needs to be applied to bare concrete before the color epoxy coat is applied – not after. Dulux epoxy is a lower-cost thin coating with an approximate 50% solids content (low). These types of coatings are not intended to be used with an actual epoxy coat primer. If you read the section under “Update” in the article above, it explains why. Dulux falls in this category. Was your concrete finish smooth or somewhat rough before you etched it? A rougher finish combined with the low-solids coating would explain your current results.

We recommend sanding the surface with 120-grit sandpaper and then applying a new color coat. Unless your concrete had a fairly rough finish at the start, this should help with covering up most of the cosmetic issues. You would then broadcast the color flakes into the coating immediately after application.

I applied 2 coats Dulux Avista water based epoxy resin tinted ( Beige Tusk ) Paint soaks and shows up the pose of the concrete which is visible small holes.

please advise if primer can be applied solve the issues as i need apply flakes before top coat sealer
