Masonry coatings and sealers are penetrating water repellents or film-forming coatings applied to brick, concrete block and stone to reduce water absorption while allowing vapor to escape. Applied after repointing and repairs, they protect the wall from freeze-thaw damage, efflorescence and staining. Statesville Roofing applies WeatherReady™ masonry sealers across North Carolina.
Brick and block are porous. A hard rain on an unsealed west wall can push gallons of water into the masonry, where it dissolves salts, freezes, and slowly breaks the wall down from the inside.
A breathable silane/siloxane repellent stops liquid water at the surface while letting vapor out. On block buildings, an elastomeric coating bridges hairline cracks and gives a uniform, cleanable finish. Choosing the right product for the substrate is the whole job.
When to seal or coat masonry
- Efflorescence or dark water staining after rain
- Interior moisture at exterior walls without a roof leak
- Freeze-thaw spalling on exposed elevations
- Porous CMU walls on warehouses and industrial buildings
- After repointing or masonry repair to protect the investment
- Graffiti or staining that needs a cleanable surface

Masonry Coating & SealersWhat you get with Statesville Roofing
Water absorption cut dramatically
Quality repellents reduce absorption by 90 percent or more on porous masonry.

Lower maintenance
Sealed walls resist staining, biological growth and efflorescence.
Extends repointing life
Sealing after repointing protects the new mortar and the units around it.
Our four-step process
The same process behind more than 98,000 service projects since 1989. No surprises, no pressure, everything in writing.
Consultation
Tell us what you are seeing and when you need it handled. A project manager, not a call center, calls you back.
Inspection
We test absorption rates, check for prior sealers, and inspect joints and cracks that must be repaired before coating.
Proposal
The proposal names the product, coverage rate, prep scope and warranty, with pricing by elevation.
Work & Quality Check
Walls are cleaned and repaired, the sealer or coating applied at the specified rate, and a water test confirms performance.
Masonry Coating & Sealers questions, answered
How long do masonry sealers last?
Penetrating water repellents typically perform for 7 to 10 years before reapplication. Elastomeric coatings carry 10-year or longer warranties depending on the system.
Will a sealer trap moisture in my wall?
Breathable penetrating repellents do not; they stop liquid water while letting vapor escape. Non-breathable film coatings can trap moisture, which is why product selection matters.
Do I need to repoint before sealing?
If joints are deteriorated, yes. Sealer cannot bridge missing mortar. We repair joints and cracks first, then seal.
