It is formulated to prime most surfaces to be waterproofed using Polyurethane membrane, including the following surface types:
Concrete, cement and cement render. Timber. Plaster Board and Fibre-Cement sheeting. Brick and Block work.
Given its inherent properties, it can also be used as a penetrative sealer.
Ensure that the primer is dry prior to the polyurethane membrane application.
It is a moisture curing, single pack, liquid polyurethane penetrating waterproofing primer.
As a primer:
Improves the adhesion and performance of the membrane.
'Locks-down' dust and loose materials.
Reduces the incidence of pinholes.
Provides a penetrative secondary waterproof barrier.
As a penetrative sealer:
Provides a penetrative waterproof barrier when applied in 2 or more coats. NB. DO NOT use as a primary waterproofing membrane.
It may be applied to the following surfaces:
Concrete, cement and cement render. Timber.
Plaster Board and Fibre - Cement sheeting.
Brick and Block work.
Ensure surface is dry prior to application.
The information contained in this product data sheet is typical but does not constitute a full specification as conditions and specific requirements may vary from project to project. The instructions should be considered as a minimum requirement but the applicator or contractor must use their skill, knowledge and experience to carry out additional works as may be necessary to meet the requirements of the project. Specification for specific projects should be sought from the Company in writing.
It should not be used as a primary waterproofing membrane.
It is not a vapour barrier and should only be used when there is a very low risk of entrapped moisture in the slab.
Benefits and Advantages
It incorporates cross- linking technology to enhance adhesion and provides a strong bond to the substrate.
Enhances the overall performance and functionality of the waterproofing membrane.
Easy to apply - single pack.
Dries quickly, with large top coating window.
Has good strength, elasticity and penetrative qualities.
Moisture curing polyurethane.
Suitable for above ground and below ground applications.
Improves easy of membrane application.
Suitable for permanent immersion of water.
Suitable for use on most porous substrates.
Precautions in Use
It contains solvent. Product is flammable. Therefore observe all the safety precautions in the Material Safety Data sheet. Ensure adequate ventilation is present when applying the product. In confined areas such as tanks ensure fresh air supply is provided and in severe cases self - contained breathing apparatus may be required. The use of gloves, goggles, coveralls and safety footwear is recommended. Keep all sources of ignition away from the product.
Priming and Surface 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.
Apply by brush, roller, squeegee or spray. Allow the product to dry before top coating it with polyurethane membrane. For best results the polyurethane membrane should be applied as soon as product has cured but with sufficient time for absorbed solvent to evaporate from the substrate and best with 36 hours of applying the primer. Longer periods will diminish the cross - linking bond between the 2 coats. Clean equipment with SOLVENT immediately after use.
The stated average coverage rate may vary depending upon type, condition, porosity, texture of the surface and application technique.
Approximately 4m2 per litre per coat.
Grey. Available in 5 and 15 Lt Pails
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.
Curing is usually 6 to 24 hours.
Store in a cool, dry area, away from naked flames or any other ignition sources. Keep out of reach of children.
CAUTION: Spills are difficult to remove. Wet utensils can be cleaned with SOLVENT. Do not allow SOLVENTS to enter the drains.
