How Much Does it Cost to Seal Brick?

The cost to seal brick are fairly low simply because you are limited to the types of sealers that can be applied to brick. The best sealer to use on red clay brick and Chicago brick pavers is a water repellent sealer like the Armor SX5000 or Armor SX5000 WB.

If you choose to apply the brick sealer yourself, you can typically do so for less than $1.00/ft2 including application materials. If you hire a professional, costs can vary greatly depending on several factors including the size of the area, and age and condition of the brick. Most costs come in around $12/00/ft2 to hire someone, but for accurate quotes, it is best to contract a local sealing company.

What is a Water Repellent Sealer and How Do You Apply it?

Water repellent sealers are penetrating sealers that chemically react to form a hydrophobic barrier within the pores. The reduce the absorption of water and other liquids on the surface, reducing damage and deterioration. Water repellent sealers also help to reduce the growth of mold and mildew, and they help to keep the brick looking cleaner, longer.

Water repellent sealers are very easy to apply. Using a pump sprayer, simply apply two coats and let dry. Water repellents sealers can last up to 7-10 years before the need for reapplication.

Why Can’t You Use an Acrylic Sealer On Brick?

It isn’t that you can’t apply an acrylic sealer to brick, but acrylic sealers should be avoided on exterior red clay brick and Chicago brick pavers. Bricks are very porous and allow for large amounts of subsurface water and moisture to pass through. Acrylic sealers are breathable and will allow small amounts of moisture to pass through, but if the moisture builds up, or if water becomes present, they will cause the acrylic sealer to delaminate and fail.

A better alternative to acrylic sealers is a penetrating sealer like the Armor WL550. The Armor WL550 functions much like the Armor SX5000 and Armors SX5000 WB, only it will slightly darken the surface of the brick to give it a slight color enhancement without leaving a visible film or surface coating.
