Instructions for use


Rain Protector is a reactive silicone in hydrocarbon solvent that has the appearance of a colourless runny liquid. It is designed to protect your brickwork, concrete or mortar against the elements for up to 12 years! It not only protects against the rain, but also frost which can cause bricks and mortar to crumble over time. It is also resistant to ultra-violet light, which can cause discolouration, and it penetrates to a depth of 5mm but still allows bricks to ‘breathe’.

Prepare It

The surface to be treated must be clean, dry and porous enough to allow Rain Protector to penetrate. Do not use detergent. You can use it on brickwork, masonry, blockwork, render or wood.

Use a wire brush to get rid of moss, lichen and other growths. Any cracks or joints should be sealed.

Apply It

Always test a small area first and allow it to dry. Use a paint brush to apply Rain Protector liberally by flooding the surface so that it runs down at least 15cm, which you then brush in. If the surface is still porous and you need a second coat then wait 36 hours before re-applying.

Dry It

Drying time will vary on the weather and the surface porosity, but will take at least 24 hours to achieve maximum waterproofing effectiveness. Once it’s dried, wait for it to rain to see just how good it is. The rain water will just bead up and run off the wall.

Cover It

Covers approximately 5m² per litre. One coat is normally sufficient, unless the surface is particularly porous.

What else do I need to know?


Rain Protector can damage glass and decorative surfaces, so protect these before you start.

Suitable for porous surfaces only, and cannot protect against rising damp.

Store It

The shelf life of Rain Protector, if unopened, is one year. Do not allow to freeze.
