A one component latex based emulsion and when mixed with fine cement provides a semi-rigid waterproof coating, used as a primer/coating system.

As a tanking membrane for internal and external walls and shower recesses. To provide a sealed surface on concrete substrates under sheet membranes to prevent "gassing". To provide an intermediate layer between bitumen membranes and coating surfaces or as an adhesive between layers of concrete. When mixed with fine cement CR25 acts as a waterproof coating on solid substrates. WESTOX CR25 will bond normal render to high strength concrete and eliminate render slide during application over all non porous surfaces.

* Unaffected by water after final set. * Excellent adhesion

* Can be applied to damp surfaces. * Increased bond strength

* Reduces efflorescence.

* Is easily repaired.

* Can be rendered or painted over.

Specific Gravity at 25’C 1.0

Vapour Transmission 9gms / m2 / 24 hours - 92% RH

pH 10.5 - 11.5

Flash Point Not applicable

Hydrostatic pressure Will work to 25m head of water

Do not apply coating if temperature is below 10’C or above 35’C.

Do not apply coating if rain is imminent.

Sound coatings may be overcoated.

The surface to be treated should be clean and sound, free from oil, grease, flaking paint, laitance and materials deleterious to the adhesion of the coating system.

Pour WESTOX CR-25 into mixing vessel, then slowly add ordinary Portland cement whilst consistently mixing, to produce a lump free consistency. If in doubt, sieve cement first.

Mixing Ration 1 part WESTOX CR-25 -1.5 to 2 parts cement by volume.

Yield 5 litre WESTOX CR-25 and 7.5 litre Cement = 10m2 @ 1mm thick (2.5 m2 per litre).

A brush or broom is the most suitable for the application of WESTOX CR25 primer and finishing coats. The product is not suitable for spraying.

Apply the first coat of WESTOX CR-25 to premoistened surface to the recommended thickness of between 0.5-1mm, brushing in one direction only. (This one application is sufficient when using as a render adhesive. Apply render while CR25 / cement is still wet or green.)

Do not brush out too thinly.

Do not use coating as a filler.

The second coat may be applied as soon as the first coat has set. Brush or broom at right angles to the previous application to ensure no pinholing occurs. Apply at the same thickness as first coat. For tanking procedures when rendering over the CR25 / cement, allow first two (2) coats to dry for 24 hours then apply third as for render adhesive.

Allow at least 16 hours before putting into service or overpainting.

Wash all equipment, brushes, containers, etc, with clean water immediately after use and before CR25 has set.

Container Size - 5 litre and 25 litre containers.

Shelf Life - 1 year in unopened container.

No special transport requirements.

Store in cool place.

Avoid repeated and prolonged skin contact with WESTOX CR-25.
