Before and After Photos Show Benefits of Proper Cleaning & Sealing of Premier Ultra Burnished Masonry Units

Mock-up Sample Wall Panel

Before project installation begins, construct a separate mock-up sample wall panel of not less than 4 feet by 4 feet with Premier Ultra Burnished Masonry Units and related Decorative CMUs in the pattern, type, color, finish and shape specified. This sample wall panel must be completed for evaluation of surface preparation techniques, application workmanship, as well as the application methods for any water repellents in mortar, and cleaning and sealing agents.

Cleaning

Always keep walls clean during construction. Wipe newly laid walls with a damp cloth or wrung-out sponge to remove green mortar. Do not allow excess mortar lumps or smears to harden on the finished surface. Harsh cleaning methods after walls have been erected might mar the surface of units.

Concrete cleaning agents are not required but are an option for Premier Ultra Burnished Masonry Units and related Decorative CMUs. There are many different cleaning agents specific to application requirements and desired results. Cleaning agent manufacturers recommended with Premier Ultra Burnished Masonry Units are PROSOCO Custom Masonry Kleaner or EcoChem NMD80.

Caution: strong acid solutions and pressure washing are never advised. They can burn mortar joints and permanently discolor the face.

Sealing

A field coat application of concrete sealer is specified on County Material's Premier Ultra Burnished Masonry Units. There are many different sealing agents specific to application requirements and desired results, including but not limited to matte finishes, high gloss, graffiti control, salt protection or densifiers. Sealing agent manufacturers recommended with Premier Ultra Burnished Masonry Units are TK Products Construction Coatings, and PROSOCO.
