BITUTHENE® Primer WB
Water-based primer for use with Bituthene membranes and underlayment
Product Description
BITUTHENE® Primer WB is a non-fibrated, stable, odour and taint-free water-based bituminous primer. It promotes good initial adhesion and more importantly, excellent permanent adhesion of Bituthene membranes.
Use
Bituthene Primer WB is used to prime many substrates including metal, slate, concrete, asbestos, cement and lightweight concrete screeds on which Bituthene membranes will be applied.
Bituthene Primer WB is used for vertical and horizontal applications at 5°C or above.
Preparation
Surfaces must be dry and clean, free from dust, dirt, grease, moss or any other foreign matter.
Application
Bituthene Primer WB is packaged ready to use. Do not dilute with water or solvent. Bituthene Primer WB can be used by roller, brush-applied or spray-applied to damp (not wet) or dry clean surface. Ensure that only an even, thin coating is applied and ensure Bituthene Primer WB has fully penetrated the substrate. Prime twice if substrate is porous. Stir emulsion well before use.
Application coverage rate is 0.5 and 0.8L / m2 per coat. Estimated coverage for concrete, cement sand screed surfaces is 0.3 and 0.5L / m2 per coat. Actual measurement may vary due to the condition of the substrate. This information is only a guide.
Allow the primer to dry one to two hours under normal condition. In humid conditions, drying time may be longer. Generally, priming should be limited to what can be covered in 24 hours. In conditions where long drying times are expected, substrates may be primed in advance. Substrates should be reprimed if significant dirt or dust accumulates.
