Acrylic Concrete Overlay SealerSureCrete’s HS 360 is a premium, high performance, single-component, 30% acrylic solids, 600 g/L, sealer designed for SureCrete overlays or other cement-based products. As with most acrylics it is vapor permeable and readily applies outside. However, HS 360 is specially formulated for extreme climates. Its nano-sealer technology deeply penetrates and reacts internally with cement, slowing moisture migration and efflorescence and intensifying bond capacity. Even in warmer climates HS 360’s slower evaporating solvents will not give a cotton candy effect before the applicator can finish a tight, smooth surface. A single coat application will provide a UV shield, enhance the beauty, and protect the surface of driveways, garage floors, patios, walkways, pool decks, and stucco.

HS 360 was made specifically in response to a growing need in climates that deal with very harsh and rapid freeze and thaw cycles. This premium acrylic sealer product penetrates into the surface of your concrete overlay and strengthens it by bonding with the cream layer of the concrete, making the entire slab much more durable and able to deal with the rapid moisture ingress and egress. While most homeowners and/or contractors have nearly written off acrylic sealers as protective coatings for their concrete overlay projects in freezing climates, anyone who trys our HS 360 product will think twice about leaving their beautiful cementitious overlays unprotected.

Here’s a list of some typical applications for SCT-EP

How Do You Apply SureCrete HS 360 Super Penetrating Concrete Overlay Sealer?

Our Acrylic Sealer products are some of the easiest to apply and use:

  1. Any surface that is about to be sealed needs to be completely cured, clean and free of all contaminants, and fully profiled and etched.
  2. Make sure that temperatures will remain between 50 and 90 degrees Fahrenheit and there will be no precipitation in the applied areas for a 24 hour period following application.
  3. HS 360 Premium Acrylic Sealer can be applied by roller, airless sprayer or pump-up sprayer. Whatever your application technique, make sure to apply in thin, even coats over your surface.
  4. Two coats are typically suggested with any exterior project receiving an acrylic sealer, with the second coat being applied as soon as first coat is able to be walked on, and is applied in the same manner as the first coat.

Frequently Asked Questions About HS 360:

Can I use just one coat of HS 360?

Technically yes, however it is not suggested. For the best results we highly recommend using two thinly applied coats. That being said, HS Series products have been known to function better than comparable sealers in situations where a single-coat exterior acrylic sealer is required.

Will HS 360 self-level and fill small holes?

No, acrylic concrete sealer products were not designed to meet this application criteria.

Will HS 360 survive the freeze/thaw cycles in my area?

If there was ever an exterior acrylic concrete sealer that could maintain proper adhesion in cold weather environments, the HS Sealers line would be the one to do it!

Can I use another, lower solids content sealer over top of HS 360?

Yes, once the first coat of HS 360 has been applied and has penetrated the surface, a lower solids acrylic sealer product such as HS 260 can be applied to keep the millage buildup of sealer to a minimum.
