How to seal pavers
Steps:
-
1
First, make sure the pavers are clean of paints, stains, sealers and any other materials that would prevent proper penetration of a sealer.
-
2
Determine the type of sealer you will be using. The type of sealer will depend on the desired end result. For example, if you want water to bead off the surface without changing the look of the pavers, you want to use a Silane/Siloxane water repellent. If you want to strengthen the pavers to prevent deterioration, you want to use a sodium or lithium silicate densifier. If you want a satin sheen, wet look or high gloss finish you want to use a 100% acrylic lacquer.

3
Two coats of any product are always recommended for best results. The material can be applied with a roller or sprayer. Which application method is best depends entirely on the product being used. Follow the manufacturer instructions.
-
4
Let dry for at least 24 hours. Do not apply when it is expected to rain within 36 hours if possible.
-
Make sure you choose the product appropriate for your application. Many of the products can be combined. For example, a sodium silicate densifier can be used before applying an acrylic lacquer. The silicate will strengthen and protect the pavers and the acrylic will enhance the appearance.
-
Do not apply when it is expected to rain within 24 hours. Rain can cause sealers to lose their bond and prematurely peel and flake off.
-
Verify the life of the sealer. Some sealers will last 6 months, others 10 years. When comparing the cost of sealers, consider the life expenctency of the sealer as well.
