Can I use polyurethane on concrete countertops?

Can I use polyurethane on concrete countertops?

Polyurethanes sealers are nearly twice as thick as an acrylic sealer and form a high-build protective film on the concrete surface that provides excellent resistance to abrasion and chemicals. They can be used on both interior and exterior concrete to impart a transparent, non-yellowing, highly durable finish.

What sealer do I use for concrete countertops?

Acrylics are a commonly used sealer. They come in solvent-based or water-based formulations (solvent-based products are often preferred). These sealers dry water-clear and are UV-resistant. Acrylic sealers can be brushed, sprayed or rolled on to the concrete.

Can you polyurethane concrete?

You can use polyurethane concrete sealers on either an interior or exterior concrete in order to create a transparent and non-yellowing durable finish. They are typically used as top coats over over an epoxy or acrylic sealers. Polyurethane (or Urethane) provides a superior resistance to abrasion and chemicals.

Is there a water-based polyurethane?

Water-based polyurethane finishes use water rather than solvents as the base for carrying the polyurethane solids. Because water-based polyurethane dry quickly, more coats can be applied in less time than with oil-based products. Water-based polyurethane begins milky-white in the can but dries clear.

How long does it take polyurethane to dry on concrete?

The dry time of a urethane will depend on the type of urethane used. It is best to speak with the manufacturer. Typically, it can take anywhere from 10-12 hours to dry before being able to be walked on, but they will continue to harden for up to 48 hours after being applied.

How do you make concrete countertops glossy?

If you want to achieve an ultra-smooth, seamless surface, then polishing or sanding the concrete after it’s cast is the best approach. Polishing can also be used to expose decorative aggregate, glass, or stone within the concrete, resulting in terrazzo-like finishes.

What kind of polyurethane do you use on concrete?

Polyurethane usually comes in satin, semi-gloss and gloss finishes. Satin finishes are generally most complementary to concrete floors; semi-gloss and gloss may imbue too much shine.

Will sealing concrete prevent stains?

Penetrating sealers (or impregnating sealers) can prevent damage and stains by holding liquids on top of the surface. They make concrete resistant to the absorption of organic materials like dirt, water, oil and salt while still allowing the surface to breath.

Is water based polyurethane any good?

Water-based and oil-based polyurethane each offer good protection; the biggest difference is in appearance. Polyurethane is actually the most durable hardwood floor finish. There’s debate over which finish is harder, but some experts maintain that hardness isn’t necessarily a good attribute of a floor finish.
