“Clear brick sealer shouldn’t form a film. It should penetrate, repel water, and still let brickwork breathe.

That’s the point of a real brick sealer.”

Designed for Australian Brickwork

Every job is different — different brick, mortar, density, absorption, and exposure. A brick sealer needs to cope with real substrates, not best-case conditions.

Inconsistent pore structure
Mixed or patched brickwork
Salt-affected masonry
Older brick walls and restorations
Brick pavers and external faces

Brickwork varies a lot. A penetrating brickwork sealer accounts for absorption differences and surface condition so the water-repellent zone is continuous and reliable.

How Brick Sealer Works

A penetrating brick sealer soaks into the capillary pore network and bonds inside the masonry, creating a water-repellent zone that reduces absorption while keeping vapour movement.

Water-Based vs Solvent Brick Sealer

Water-based sealers can work on very porous brick. On older or denser brickwork, solvent-based penetrating sealers often achieve more predictable penetration and coverage. Choose based on substrate and warranty risk, not convenience.

FAQ

Is brick sealer breathable?
Yes — a penetrating sealer repels liquid water while allowing vapour movement.
Does brick sealer change the look?A clear penetrating brick sealer should not leave a film or visible coating when applied correctly.
Brick wall waterproofing vs brick sealer — same thing?Most “brick waterproofing” products are brick sealers. The difference is whether they penetrate (good) or film-form (often problematic).
What causes most failures?
Poor prep, uneven absorption, under-application, sealing over existing coatings, or expecting a sealer to fix cracks/structural water entry.
Can I use it on brick pavers?
Yes, if they’re porous. Test first. Pavers may need different coverage than vertical brickwork.
How do I buy Silonexx?

Do you sell to homeowners?
Yes, if they’re porous. Test first. Pavers may need different coverage than vertical brickwork.
