SikaTite BE Bitumen Waterproofing Membrane 15L

SikaTite BE is a water based bitumen emulsion modified with acrylic latex polymers. It can be applied as a waterproof membrane, sealant, protective coating or adhesive. It is designed for use underground, internal and immersed areas.

Ideal for:

APPLICATION

Surface Preparation:

Remove dirt, dust, oil, grease and all other contaminants from the surface. Any surface irregularities should be filled using repair mortar. A priming coat must be used on all substrates as part of the surface preparation. On concrete and masonry substrates the prime coat can be formed using the acrylic based SikaTite Primer, or by diluting 1 part SikaTiteBE with 3 parts water. On asphalt, bitumen, treated metal, plastic or smooth substrates, the prime coat should consist of 1 part SikaTite-BE and 1 part water.

Mixing:

One component: When SikaTite-BE is applied as a one component system, it is recommended that the material be lightly stirred before application.

Two component: SikaTite-BE can be mixed with a sand and cement mix, or a pre-bagged mortar to form a mortar, screed, or render, with waterproofing properties.

To create a mortar, add SikaTite-BE to a pre-formed sand/cement mix. 3 parts sand to 1 part cement should be mixed with water to form a working mortar before SikaTite-BE is added. The greater the amount of SikaTite-BE added will result in a more waterproof and flexible finish (use 3 parts mortar to 1 part SikaTite-BE as a starting point).

This application is ideal when forming fillets at junctions, levelling floors and walls, filing voids or forming low build waterproof screeds.

Placement:

SikaTite-BE can be applied by brush, roller, airless spray or trowel. It can be applied to horizontal or vertical surfaces. For general waterproofing work, SikaTite-BE should be applied at a minimum of 2 coats. It is recommended that 2 coats be applied at a total minimum of 1.5 litres per m2 to give a wet film thickness of approximately 1.2 mm. Apply subsequent coats at different directions to the previous. Coverage is dependant on the condition of the surface and will vary accordingly.

Reinforcement can be provided using Sika Fabric embedded in between coats of SikaTite-BE. The fabric should be used over cracks (up to 2mm), and joints. The fabric should be applied into the first coat of SikaTiteBE whilst it is wet, and it should not be visible after the final coat. Refer to the Technical Data Sheet for more detailed information.

Clean Up:

All tools and equipment can be cleaned with water immediately after use. Hardened material can only be removed mechanically.

Stored in original sealed packaging, in dry conditions away from direct sunlight, this product will keep for at least 12 months.
