Cleaning Tools

All tools and brushes to be cleaned with White Spirit after use.


All surfaces to be treated should be dry, clean and free from dirt, dust, oil, grease and organic growth.

Surfaces may be washed down with clean water but detergents of soap solutions should not be used.

Do not apply Exterior Water Seal for 2 to 3 days after rain as this will effect penetration.

Defective mortar should be removed and replaced with new prior.

The product will not be effective on materials that are unsuitable for exterior use.

Exterior Water Seal should not come into contact with windows or other glazed areas, which should be masked to prevent splashes.

In such instances contaminated areas should be wiped immediately with White Spirit.

Exterior Water Seal is ready to use and should not be diluted.

Shake container before use.

The material should be applied liberally by soft bristled brush or low-pressure airless equipment avoiding mist forming by using a course spray nozzle.

On masonry a single application is normally all that is required but on porous surfaces a second application may be applied as soon as the first coat has dried.

On wood, two coats are also required.

Treatment should start at the top and work down.

Exterior Water Seal cannot be over-painted therefore it should be used as a final application only, as it may affect the adhesion of subsequent coatings.
