Concrete cure and seals are designed to cure and seal new concrete surfaces. There are many benefits to using a cure and seal, including:
- Cure and seals help concrete to properly cure be controlling the amount of water able to escape the concrete during the concrete.
- Cure and seals help to protect the surface against water absorption from rain, snow, and pool water.
- Cure and seals help to protect the surface against deterioration caused by surface abrasion.
- Cure and seals help to protect the surface against staining.
When you think of a concrete cure and seal you think of an acrylic sealer. What you aren’t always aware of is that there are several types of acrylic sealers that can be used. Here are a few of the many different factors to consider when choosing a cure and seal:
- Specifications – A true cure and seal should be ASTM 1315 and ASTM C 309 approved. These are standard tests that determine the suitability of a product to properly cure and seal new concrete.
- Solids Content – Solids are directly associated with active materials. Low solids solutions are cure and seals containing 15% or less active materials, while high solids solutions are cure and seals containing 20-25% active materials. Cure and seals containing 20-25% active materials will have a stronger coating and offer a higher level of gloss than 15% solid solutions.
- Base – Cure and seals are available in water based and solvent based solutions. When choosing a base, don’t think about today, think about next year, and the year after. Water based cure and seals require more work to maintain, repair, and re-coat. Screen sanding is typically required, and in some cases, the coating may need to be removed. Solvent based cure and seals can easily be repaired with Xylene, and re-coating is as easy as applying a fresh coat to a clean and dry surface.
How to cure and seals differ from sealers that can be applied to new, uncured concrete? There are lots of products on the market, sealers in particular, that can be applied to new concrete. They won’t help the concrete to properly cure, but they will protect the surface during the curing process. This is a popular option for people that don’t want a coating, but want to help reduce staining and deterioration caused by water absorption while the concrete is curing.
