Sandtex Smooth Masonry Paint - Black 10L with 15-Year Weatherproof Protection

Long-lasting exterior protection with Microseal technology:

Sandtex Smooth Masonry Paint uses Microseal® technology to form a tough, breathable barrier across exterior masonry surfaces. The microporous formulation prevents water penetration while allowing trapped moisture to escape, reducing the risk of peeling, cracking, and flaking over time. This 10 litre tub in Black delivers up to 160m² of coverage and is backed by up to 15 years of proven weatherproof durability.

Quick-drying and suitable for a wide range of surfaces:

The paint is touch-dry and recoatable in 3 to 4 hours, and rainproof in just 1 hour - practical when working around unpredictable weather. It is suitable for application on breeze blocks, concrete blocks, pebbledash, rendering, roughcast, and facing bricks. Apply using a synthetic bristle brush, masonry roller, or spray for a smooth, soft-sheen finish.

Dirt-resistant and low in VOCs:

A slow-release biocide protects the coating against mould and algae growth over an extended period, helping the finish stay cleaner for longer. The water-based formula has a VOC level of just 1 g/litre, making it a low-emission option for exterior renovation work. The finish is also washable and wipeable once fully cured.
