“Brick acid” is the trade name for dilute hydrochloric acid, widely used by builders, bricklayers and driveway cleaners to remove mortar smears, efflorescence and general grime from brick, stone and concrete surfaces. Easy Chemicals Trade supplies brick acid in trade quantities across the UK, to the same specification used by professional cleaning and construction teams.
What is brick acid?
Brick acid is hydrochloric acid diluted to a lower working strength, typically around 10%, making it suitable for general masonry cleaning without the extra handling requirements of stronger, concentrated grades. It dissolves cement and mortar residue, limescale and efflorescence (the white staining that appears on brickwork), restoring the original appearance of the surface.
What is brick acid used for?
- Removing mortar smears from new brickwork after laying.
- Cleaning patios and driveways of grime, moss and mineral staining.
- Treating efflorescence on brick and block walls.
- General masonry and concrete cleaning where a mild acid wash is appropriate.
Easy Chemicals Trade supplies this as Hydrochloric Acid 10% Poly, the standard brick acid strength, in trade pack sizes with quantity pricing, from a UK chemical distributor.
Using brick acid safely
Always follow the dilution and application instructions on the product label and safety data sheet (SDS), never add water to acid, and wear appropriate protective equipment including gloves and eye protection. Test on a small, discreet area first, since some stone and coloured mortar can be sensitive to acid cleaning. Rinse the surface thoroughly with water after use.
