FAQs

How long will Dulux Weathershield Smooth Masonry Paint last?

This paint is formulated to provide total protection and last for up to 15 years on exterior masonry surfaces, assuming proper application and surface preparation.

Can I use this paint on any exterior surface?

No, it is specifically designed for exterior masonry surfaces such as render, concrete, brickwork, and stone. It is not suitable for wood, metal, or other non-masonry materials.

How quickly does it become rainproof?

Its quick-drying formulation allows it to become rainproof in just 30 minutes, providing a protective barrier against rainwater.

Does it protect against mould and algae?

Yes, the paint film contains an algicide and fungicide to protect against staining caused by mould, algal, and fungal growth.

Will this paint cover existing cracks?

It features a flexible paint film designed to cover minor imperfections, including hairline cracks across different surfaces. Larger cracks should be filled prior to painting.

Is this paint breathable?

Yes, it has a micro-porous breathable paint film that allows moisture and air to be released from the walls while preventing rain from penetrating.

What is the recommended application method?

For best results, apply with a brush or roller. Refer to the product's packaging for specific application instructions and recommended number of coats.

Troubleshooting

Paint not adhering or peeling prematurely

Ensure the surface was thoroughly cleaned, dried, and free from loose material before application. Any existing flaking paint should be scraped off and sanded smooth.

Mould or algae reappears quickly after painting

While the paint film is resistant, severe existing mould or algae must be treated with a fungicidal wash *before* painting to prevent it from growing through the new paint layer.

Uneven finish or brush marks visible

Apply paint evenly using a good quality brush or roller. Ensure consistent application thickness and avoid overworking the paint. Apply in appropriate weather conditions, avoiding extreme heat or cold.

Paint takes longer than 30 minutes to become rainproof

Check ambient temperature and humidity. Cooler temperatures and higher humidity will extend drying times. Ensure paint is applied thinly and evenly.

Setup, Compatibility & Care

Setup

Proper surface preparation is crucial for the 15-year guarantee. Ensure the masonry surface is clean, dry, and free from loose material, dirt, or grease. Treat any existing mould or algae with an appropriate fungicidal wash before painting. Fill larger cracks or defects with a suitable exterior filler. For very porous or powdery surfaces, a stabilising primer or sealer may be beneficial, though not explicitly stated as required by the product description. Stir the paint thoroughly before and during use.

Compatibility

This paint is specifically formulated for exterior masonry surfaces, including render, concrete, brickwork, and stone. Do not use on non-masonry surfaces or surfaces that require different paint properties.

Care

Once applied and fully cured, the paint film itself is resistant to mould and algae and designed for extreme weather. For general maintenance, simply clean the painted surface periodically with a soft brush and water to remove dirt and grime. Avoid abrasive cleaners or harsh scrubbing, which could damage the paint film.
