It's important to prepare the concrete steps properly before attempting to apply the brick veneer. Removing all bulges, rough edges and uneven areas from the surface, using a masonry wheel winder, helps produce a smooth and even surface. This preparation will help to achieve proper mortar adhesion and a level surface to lay the bricks. For final preparation, clean the surface with an acid cleaner, rinse it thoroughly and allow it to dry completely before beginning brick application.
It's important to use a type "M" mortar mix for exterior use to adhere your bricks to the concrete surface. This type of mortar has the highest amount of Portland cement and is formulated to hold up to ice and snow conditions. The bond strength of this mortar is greater than other types, making it an ideal choice for horizontal paving applications.
For a successful brick veneer application, ensure that the temperature of the concrete surface is above freezing, before you begin. The optimum temperature range is between 35 and 120 degrees Fahrenheit. Choose bricks with dimensions that require you to make as few cuts as possible to cover the steps. To support the brick veneer on the sides of the steps and the first riser, you will need a concrete footing for them to rest on. Begin your project by adhering the bricks to the footings and work your way up the sides of the stairs and the risers. Finally, secure bricks to the treads. Ensure that the bricks are level and straight by checking them regularly with a level throughout the installation.
To protect the surface of your new brick veneer, applying a masonry sealer is a beneficial step. The sealer protects the texture and surface from scratches. It will also prevent stains from setting into the surface. There are several stain finishes to choose from, including low sheen, high sheen, low gloss, high gloss and matte. Before application, you must allow the mortar to cure for at least 30 days. Once applied, allow it to dry according to the manufacturer's instructions. To preserve the protective coating, reapply the sealer every 1 to 2 years.
