Acrylic based bitumen waterproofing membrane
Description
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.
Uses
SikaTite-BE is suitable for use in commercial, residential, industrial, rural and automotive applications. Waterproofing applications include: Retaining walls. Cellars and basements. Planter boxes. Ponds, tanks and water features. Gutter repairs. Roofing. Silos. Repair of existing bitumen surfaces and membranes. SikaTite-BE can also be mixed with sand and cement to create waterproof screeds, renders, fillets and fillers. SikaTite-BE is suitable for application to common building substrates including concrete, render, masonry, fibre cement, sheet, timber, clay brick, concrete block, aerated concrete, asphalt, treated metal and existing bitumen.
Advantages
Water based, free of solvents and toxins. Excellent waterproofing properties. Can be used in varying thicknesses. Excellent bonding capabilities. Can be applied to damp surfaces. Can be mixed with sand/cement to improve adhesion, tensile strength, flexibility, sound dampening and to create falls. Approved for use in potable water (AS4020:1999) Can be painted or coated over. Easy to apply and work with. Can be applied to a wide range of substrates.
Storage and Shelf Life
Stored in original sealed packaging, in dry conditions away from direct sunlight, this product will keep for at least twelve (12) months.
Instructions for Use
Surface Preparation
Remove dirt, dust, oil, grease and all other contaminants from the surface. Any surface irregularities should be filled using SikaMonoTop repair mortars, Sikadur-41 epoxy repair mortar, or a repair mortar incorporating SikaTite-BE.
Priming
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.
Application
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. Sika Tite-BE 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. 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 such as SikaTite Filler, 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.
