Frequently Asked Questions – Building Chemicals

What are building chemicals used for?
They improve the performance of building materials, aid in curing, bonding, waterproofing, or surface cleaning — especially during bricklaying, rendering, or groundwork.

Can brick cleaner damage brickwork?
Brick acid is safe for most standard clay bricks but should not be used on handmade or sensitive materials. Always test on a small area and avoid natural stone surfaces.

What does a mortar plasticiser do?
It improves mortar workability and adhesion, reduces cracking, and replaces the need for lime — ideal for bricklaying in cold or dry conditions.

Should I seal brickwork after cleaning?
Yes, applying a sealer after cleaning helps protect bricks from water ingress, staining, and frost damage — especially on exposed or high-traffic areas.

Are these products trade quality?
Yes — we supply trade-grade building chemicals suitable for site use and serious DIY projects, with clear usage instructions and safety data available.
