Can you recoat RockSolid?
A second coat of RockSolid® Floor Coatings can be applied. The floor can be recoated after 8-12 hours and before 7 days without sanding the surface for proper adhesion of the second coat. If more than 7 days has passed, sand the surface with 60-80 grit sandpaper before applying the second coat.How long does epoxy clear coat take to dry?
Dry time for foot traffic in 18 hours and heavy traffic in 24 hours at room temperature (70° degrees F) regardless of thickness. Drying times are longer at cooler temperatures. Temperature and humidity can affect dry time. AS WITH MANY HIGH PERFORMANCE FLOOR COATINGS FULL CHEMICAL RESISTANT CURE IS 3 DAYS.Can I put epoxy over epoxy?
Can I put another coat of epoxy over cured epoxy? Yes. Since the epoxy has cured a chemical bond is not possible so what is called a mechanical bond is needed. This simply means that the cured epoxy has to be lightly sanded before the next coat is applied: the first coat should have a matt, almost white, surface.How long does it take rustoleum epoxy to dry?

Can you use water based Poly over epoxy?

However, I can see scratch lines on the epoxy from the wet/dry paper through the polyurethane finish.Can I use polyurethane on countertops?
Polyurethane varnish is one of the best finishes for a countertop -- it's durable and, when applied properly, can be just as subtle as lacquer. Best of all, applying polyurethane doesn't require spray equipment and is a job you can easily do yourself. Oil finishes tend to soak into the grain and yellow.Can polyurethane be used as resin?
Polyurethane resin is used in an extremely wide range of production products, such as rubbers to medicines. There are many advantages to polyurethane resins. They are commonly noted for their chemical, oil, and grease resistance, and they are typically very good at resisting abrasion and, as such, are not easily torn.What is the difference between epoxy and polyurethane?
The main operational differences between epoxy and polyurethane are:1. Epoxy floors are usually harder than polyurethanes, For Epoxy they have higher compressive and impact strength2. Polyurethane floors are usually softer and elastic. This gives them a better resistance and scratching.Can I stain over epoxy?
You can stain over epoxy if you're using a gel stain, which works like paint more than stain. Epoxy, like any plastic, won't absorb coloring and most likely the stain will rub off of the spot while you apply the finish (assuming you're using a wipe-on). The dust within the glue will accept stain-oil-varnish etc.Can you put polyurethane over glaze coat?
You can turn any clear finish into a glaze by adding pigment, or you can buy a pre-mixed glaze. Oil-based polyurethane and epoxy resin glazes work best on cured polyurethane. Apply with care.Can I paint epoxy over enamel?
From majestic jets to plain tugboats, enamel is commonly used on surfaces that require a durable coat of paint.

As long as you pour in 1/8" layers, you can go as thick as you like. The reason we recommend this thickness is two-fold: first, it allows the bubbles to escape properly, and second, it avoids any excessive overheating of the resin. So for best results always pour in a 1/8" layer, and you're good to go!Does epoxy stick to varnish?
As a general rule, epoxy should not be applied over other coatings.

If a sealer was previously used on the concrete (if water beads up on the surface), do not use epoxy.Can you put concrete sealer over sealer?
Resealing concrete is nothing like sealing new concrete. Sealing new concrete requires a good bond to a concrete surface. On the other hand, resealing a surface requires adhesion to an existing sealer. Applying new sealer is most often perceived as a new layer over an old one, but this should not be the case.What is the difference between epoxy and sealer?
They produce a hard, abrasion-resistant, long wearing surface. Epoxy coatings are available in clear or can be colored. They are water repellent, however, different than acrylic sealers they are non-porous and do not allow the trapped moisture to escape. Epoxy sealers are harder than acrylic sealers.Is epoxy stronger than cement?
compressive strength typically only has about 300 lbs. of tensile strength. By comparison Epoxy.com Product #10 Epoxy Mortar has a compressive strength of 10,000 PSI (about 3 times that of standard concrete) but Product #10 Epoxy Mortar has a tensile strength of 3,500 psi (at least 10 time stronger than concrete).
