DESCRIPTION:
Submersible waterproofer for waterproofing of showers, fishponds, reservoirs, walls, decks, balconies etc

USAGE:
AL400 is formulated for use in bonding slurries, screeds, renderings, pavings and other cementitious mixes where it wholly or partially replaces the water content of the mixes and brings the following benefits to cementitious mixes:

• Excellent bond, flexural and tensile strength
• Extreme resistance to water and water vapour - Good abrasion and chemical resistance
• First-class bonding to asphalt
• Thin screeds which are water / vapour proof - Low water / cement ratio
• Resin performance at economic cost - Reduced drying shrinkage
• Easier site use
• Compatibility with all cements
• Non-expensive surface preparation

APPLICATION:
Preparation:
Clean all surfaces of dirt, dust, oil and stains. Check that the substrate is in a sound condition and cured. Fill the cracks with one part AL400 and one part Portland cement before waterproofing

Method Of Application
After preparing the substrate as described above, thoroughly brush two sealing coats consisting of approximately two parts Portland cement slurried with one part AL400 on to the surface. Apply the second sealing coat as soon as the first coat is touch dry i.e. after approximately 20 - 30 minutes. Apply the sealing coats at right angles across each other, thus ensuring complete coverage of the substrate. It is emphasised that the thickness of each sealing coat should not exceed 1.6mm. The double sealing coat system must dry out completely for a period of at least 48 hours. Thereafter apply a tack coat consisting of two parts Portland cement slurried with one part AL400. Apply the plaster while the tack coat is still wet.

Plastermix
6 Litres of AL400 / 50kg cement. Where high hydrostatic pressures are anticipated, the recommended level of AL400 is 12 litres / 50kg cement. After the plaster has been applied, leave it to cure for 72 hours. For shower walls, apply the tiles immediately, while the tack coat is still wet. Leave for 72 hours after the tile application. Wash tools with water immediately after use.

FUNCTION
AL400 has been specifically formulated for use in bonding slurries, screeds, screeds, renderings, pavings and other cementitious mixes. It wholly or partially replaces the water content of the mixes. The AL400 based slurries form a protective rubber-like skin which is tightly bonded to the substrate and the sand/aggregate particles in the mix are wrapped in rubber-like socks; the addition of AL400 slightly darkens the mixes.

Unlike some polyvinyl acetates, AL400 does not re-emulsify and once cured, the bond is unaffected by water or water vapour.
Frequently, AL400 can be an economic replacement for epoxy and other resin products and it is easier to use.
