Product Information

Full details

This Zinsser All Weather 5L Black masonry paint is designed for homeowners and professional decorators seeking a durable, long-lasting finish on exterior masonry surfaces. Its key benefit is its ability to be applied in very low temperatures, down to -5°C, and its quick drying time, allowing for year-round application regardless of weather conditions. A potential caveat is that it contains a biocide to protect the dried film, which is important for users to be aware of.

FAQs

Can I apply this paint in freezing temperatures?

Yes, Zinsser All Weather Masonry Paint can be applied at temperatures as low as -5°C. However, ensure the surface itself is not frozen.

Do I need to use a primer with this paint?

In many cases, it is self-priming and will bond to existing paints without sanding. However, for bare, chalky, or highly porous surfaces, a Zinsser primer may still be recommended for optimal adhesion.

How long does it take for the paint to be showerproof?

The paint is showerproof in approximately 20 minutes after application.

What is the coverage rate of this paint?

The coverage rate is approximately 12 square metres per litre.

How should I clean my brushes and rollers after use?

Clean all tools and equipment with water immediately after use.

What does 'contains a biocide' mean?

It means the paint contains an active ingredient (biocide) that protects the dried paint film from attack by fungal and algal degradation. Once dried, the paint film is classified as a treated article.

Can this paint be used on interior masonry?

This product is specifically designed for exterior masonry surfaces and is not recommended for interior use.

What is the difference between touch dry and full cure?

Touch dry means the surface is dry to the touch and unlikely to be easily smudged. Full cure means the paint has hardened throughout and achieved its maximum durability and resistance. Full cure takes 7 days.

Troubleshooting

Paint not adhering well

Ensure the surface was properly prepared and free from dust, dirt, and grease. If applying to bare or highly porous surfaces, consider using a Zinsser primer before painting.

Uneven finish or brush marks visible

Ensure the paint is stirred thoroughly before and during application. Apply in even coats, maintaining a wet edge to avoid lap marks. Use a good quality brush or roller suitable for masonry paints.

Paint taking too long to dry

Drying times are dependent on temperature and humidity. Ensure application is within the recommended temperature range (above -5°C) and avoid painting in very humid conditions. If applied too thickly, drying may be extended.

Fungal or algal growth appearing on the surface

While the paint contains a biocide, heavy contamination or a very damp environment may still lead to growth. Clean the affected area thoroughly. Ensure the surface is dry and well-ventilated before repainting. Check that two coats were applied.

Pros and Cons

  • Requires two coats for optimal protection and appearance.
  • Contains a biocide, which may be a consideration for some users.

Setup, Compatibility & Care

Surface Preparation:

Ensure all surfaces are clean, dry, and free from dirt, grease, and loose or flaking paint. Remove any existing mould or mildew. In many instances, the paint will act as a self-primer on previously painted surfaces, bonding without the need for sanding. However, for bare, porous, or chalky surfaces, a suitable Zinsser primer may be required for optimal adhesion.

Compatibility:

Suitable for bare or previously painted masonry surfaces including concrete, render, stucco, brick, and stone. It is designed for exterior use.

Application:

Stir thoroughly before use. Apply by brush or roller. Two coats are recommended for best results. Apply the first coat and allow it to dry for a minimum of 3 hours before applying the second coat.

Coverage:

Approximately 12m² per litre.

Drying Times:

  • Touch Dry: 1-2 hours
  • Recoatable: 3 hours
  • Showerproof: 20 minutes
  • Full Cure: 7 days

Care:

Clean tools and equipment immediately after use with water. The dried paint film contains a biocide to protect against fungal and algal degradation. After the paint is fully cured, the surface can be wiped down with a damp cloth and mild detergent if necessary.
