Changes to the way you can order
Due to increased delivery costs, we need to implement a minimum order value across our product ranges. With effect from Thursday 26th November 2020, the minimum order value will be £200 (ex VAT) / £240 (inc VAT). This will enable us to continue to keep our prices low and our service levels high. We thank you for your business and continued support during these unprecedented times.

Bituthene Primer B1 is a solvent-based bituminous primer used to prepare vertical and sloping surfaces and suspended slabs, for Bituthene GP. It is a quick drying, all temperature primer to enable same hour application.


  • Primer B1 can be used at minus 5°C or above
  • Size: 5L
  • Coverage: 10-12 m2 per litre
  • Curing at 20 °C - 30 minutes
  • Compatible with Bituthene® GP


This primer cannot be used to prime green concrete or damp to touch substrates. It is suitable for use on masonry or wood surfaces on which Bituthene GP membranes will be applied.

Bituthene® Primer B1 may be applied by a roller or a brush. Apply it to clean, dirt free, surfaces at a coverage rate of 8-10 m2 per litre. Allow the primer to dry 30 minutes or until tack-free. Dry time may be longer in cold temperatures. Deep puddles of primers should be avoided as this will lengthen drying time. Do not apply directly to Bituthene® membrane.

In general, priming should be limited to an area that can be covered with membrane on the same day. Areas that accumulate significant amounts of dust or dirt must be re-primed before membrane is applied.

This product is non-returnable due to shelf-life and quality control.
