This primer is suitable for use on damp to touch substrates, but it cannot be used to prime “green” concrete. It can be used on masonry or wood surfaces on which all GCP post applied membranes will be applied. Primer W2 can be used at 0°C or above.
BITUTHENE® Primer W2 is supplied ready to use. Do not dilute with water or solvents. BITUTHENE® Primer W2 may be applied by a roller or brush. Apply it to clean, dirt free, frost-free surfaces at a coverage rate of 9-11 m2 per litre. Allow surface conditioner to dry completely and thoroughly prior to membrane application.
The surface conditioner is considered dry when the substrate returns to its original colour. To test for dryness, rub small conditioned area by hand. Wet conditioner will ball up under the fingertips. Allow to dry until conditioner cannot be rubbed off. If conditioned areas are not covered that day, re-condition the area if there is significant dust or dirt contamination.
