FLEXIBLE CEMENTITIOUS WATERPROOF MEMBRANE

Preparation
It is essential that adequate preparation is carried out prior to the application of SpECtite CW100.

The substrate must be clean and completely free from contaminants including grease, oil and loose material. Any repairs to the substrate should be carried out using SpECbuild cementitious repair mortars.

Mixing
SpECtite CW100 is supplied as a two component pack consisting of a liquid component and a powder componentThe product cannot be mixed by hand. The liquid should be poured into a 25 litre plastic or metal drum. The powder should be added slowly whilst mixing with a spiral paddle attachment on a slow speed electric drill. Mixing should continue until the product is lump free and for a minimum of 5 minutes.

Application
The prepared substrate should be dampened using a fine water spray. Care should be taken with porous substrates as more extensive pre-soaking will be required. Any free water on the surface should be removed immediately prior to applying SpECtite CW100.
While the substrate is damp but free from standing water, apply the mixed product a minimum of 2 coats by medium hard short bristle brush, trowel or roller checking that the first coat is at a minimum wet film thickness of no more than 1.5mm and no less than 0.5mm. The product should always be finished in one direction.

The second coat should be applied as soon as the first coat is set hard, normally after a minimum of 3 hours @ 25°C and longer at lower temperatures. This second coat should again be finished in one direction (at 90° to the first coat).
The total thickness should be 2mm on walls and 3mm on floors.
