The SealMaster Concrete Sealer is an acrylic surface sealer that is meant for decorative concrete and other, more delicate concrete slabs. As an acrylic sealer, it will not penetrate within the concrete slab, as will a penetrating sealer. This makes it less long-lasting, but also more appropriate for specific projects like decorative concrete.

The SealMaster sealer is a water-based product that is a 100% acrylic solution pre-mixed with water. It promises to dry clear and protect concrete from penetration through the surface of water, debris, and dirt. However, an acrylic sealer cannot truly offer guaranteed protection from surface penetration. Where a penetrating sealer will chemically react to lock out those intruders, an acrylic sealer is more like a raincoat: the water will bead and roll off at first, but the water will seep into the concrete with too much prolonged exposure.

The SealMaster Concrete Sealer is an adequate and average product offering protection for your more delicate concrete products. It is not as chemically harmful as other products, and it offers an average coverage of 200 to 300 square feet per gallon (depending, of course, on your particular project).
