Dulux Weathershield Masonry Paint - Black - 5L

This paint is formulated to provide up to 15 years of weather protection, provided surfaces are properly prepared and the paint is applied correctly according to the instructions.

Yes, it is suitable for most exterior masonry surfaces including render, concrete, brickwork, and stone. For very porous or powdery surfaces, a primer or stabiliser is recommended prior to painting.

Generally, two coats are recommended for optimal coverage, durability, and to achieve the full protective benefits and uniform finish of the paint.

Since it is a water-based paint, brushes and rollers can be cleaned immediately after use with warm, soapy water.

It is not recommended to apply this paint in temperatures below 10°C or when rain is expected within the drying period, as this can negatively affect drying time and adhesion.

'Stay-Clean Technology' is a special formulation within the paint that helps to repel dirt and prevent the growth of mould and algae on the paint film, keeping your exterior walls looking cleaner for longer.

Ensure the surface was thoroughly cleaned, dried, and free of loose material before application. For very porous or powdery surfaces, a stabilising primer might be needed to improve adhesion and prevent flaking.

Before painting, ensure all existing mould and algae were completely removed using a dedicated fungicidal wash, then rinsed. The paint's 'mould and algae protected film' inhibits growth, but existing spores must be eradicated first.

Ensure the paint is stirred well before and during use to maintain consistency. Apply evenly, avoiding overspreading or applying too thickly. Use a good quality brush or roller and maintain a 'wet edge' during application to prevent marks.
