Bituflex is a water-based 'rubberised' latex / bituminous waterproofing compound incorporating elastomers and reinforcing agents. It is formulated to a brushable consistency, but with sufficient body to provide a high build waterproofing membrane. Bituflex is user friendly and non-hazardous. Although black in colour it will not stain grout or tiles and it will not re-emulsify after fully curing.
Bituflex is designed as an economical waterproofing solution for many applications which are to be covered, tiled or topped including:
Decks, patios, balconies, terraces etc.
Bituflex is suitable on most commonly used construction substrates. These substrates should be sound, stable, clean, dry and free of loose matter and contaminants:
FC sheeting and compressed sheeting
Bituflex can be applied to damp surfaces but freedom from surface water and continual dampness is essential. The product will not cure if surface remains damp.
The information contained in this data sheet is general in nature and refers only to the usual use of the product and it should not be construed to be a complete specification. Site conditions vary which may require the use of the products and related products to vary. For specific projects a written specification should be sought from the Company.
Bituflex is not designed for exposure to the sun.
Bituflex will not become waterproof until it had fully dried and cured. Protect from rain until it has cured.
Bituflex is not compatible with acid based sealants. Ideally Bituflex should be coated with Wrimco Primeseal before applying sealant to it. Neutral cure sealants are preferred.
Bituflex is not a trafficable membrane.
Benefits and Advantages
Easy to apply.
Will not stain grout and tiles after proper tiling.
Compatible with most tile adhesives.
Precautions in Use
Do not apply in areas exposed to the weather if rain is imminent.
Priming and Preparation
Good preparation is essential. Surfaces must be sound, stable, dry, clean and free of dust, loose, flaking, friable material and substances that may diminish adhesion.
Drying and Curing
Drying and curing of the product is affected by type, dryness and porosity of the surface, temperature, humidity, ventilation, climate conditions and application technique and therefore drying and curing can only be given as a guide.
Generally at 25oC at 50RH:
Touch dry: 4 to 6 hours
Fully dry: 12 to 24 hours.
Full cure: 36 hours
Keep in cool dry conditions.
Do not let product freeze.
Product is non flammable and non-hazardous.
Wet spills can be cleaned with water.
Tiling, Topping or Top Coating
Bituflex is compatible with most tile adhesives. Ensure adhesive is compatible with flex of the surface.
Do not tile until product has fully cured. Rubbing with damp cloth that produces no stain indicates full cure.
Adequate expansion joins should be installed in accordance with good tiling practice as per AS3951.1:1991.
Bituflex can be topped with sand:cement topping.
Safety & Precautions
The use of gloves and goggles against splashes are recommended.
If in eyes, flush thoroughly with clean water, holding open to ensure trapped product may be flushed away.
If swallowed, give water to drink and seek medical advice.
If inhales, unlikely due to products viscosity, remove to fresh air and apply artificial respiration if required and seel medical attention.
If on skin, remove contaminated clothing and wash skin with soap and water.
