Brickwork Sealer: Protection, Performance, and Appearance

What is a brickwork sealer?

A brickwork sealer is a protective coating applied to brick, mortar, or brick slip surfaces to help prevent moisture penetration, staining, and weather damage. Sealers can be clear or tinted, matte or gloss, and are designed to preserve both the performance and the visual appeal of brickwork over time.

Used correctly, a brickwork sealer helps maintain colour vibrancy, reduces efflorescence risk, and can extend the lifespan of masonry.

Why sealing brickwork is important

Moisture resistance: Helps prevent rainwater absorption which can lead to frost damage and internal damp issues.
Stain prevention: Reduces the risk of dirt, algae, or oil penetrating the surface.
Colour retention: Protects against UV fading for a longer-lasting finish.
Easier cleaning: Sealed brickwork is simpler to maintain as dirt sits on the surface instead of soaking in.

Types of brickwork sealers

Penetrating Sealers: Absorb into the brick, creating an invisible barrier while allowing the surface to breathe.
Film-Forming Sealers: Create a visible coating on the surface, available in matte or gloss finishes for a decorative effect.
Breathable Sealers: Allow moisture vapour to escape while blocking water ingress, ideal for older buildings or heritage brickwork.

Using sealers with brick slips

When sealing brick slips:

Ensure the surface is clean, dry, and free of dust.
Test a small area to confirm the finish meets expectations.
Apply evenly with a brush, roller, or sprayer according to manufacturer guidelines.
Reapply as recommended to maintain full protection.

A brickwork sealer is more than just a finishing touch. It is an investment in keeping walls looking their best while defending them from the effects of weather and wear.
