Description

Improves adhesive strength

Excellent adhesion to a wide range of surfaces

Rough and porous surfaces are strengthened

Simple use

Apply butyl primer to the surface being treated with a brush and let the surface flash off until the primer stiffens and exhibits a strong surface adhesiveness.

Notice

Thin thickened primer with light petrol to apply it again.

The usage instructions are recommendations based on the tests we have conducted and on our experience; carry out your own tests before each application. Due to the large number of applications and storage and processing conditions, we do not assume any liability for a specific application result. If our free customer service provides technical information or acts as an advisory service, no responsibility is assumed by this service except where the advice or information given falls within the scope of our specified, contractually agreed service or the advisor was acting deliberately. We guarantee the consistent quality of our products. We reserve the right to make technical changes and further develop products. Please observe the technical data sheet!

Usage

Application area

Butyl primer is always required for optimal adhesion on porous and absorbent surfaces such as concrete, aerated concrete, plaster, cement stone, gypsum, wood, fibreboard, chipboard or gypsum board, masonry, sand-lime brick, etc. To improve adhesive strength on oxidised metals such as iron, lead, etc., these surfaces must also always be treated with a primer.

Can also be used for pre-treatment of adhesive surfaces in roof and concrete construction and for sealing of construction joints with butyl tapes.

Butyl primer is required for all self-adhesive Würth butyl and bitumen tapes.

Instructions

The surface to be primed must be dry, load-bearing and free from dust and release agents.

Apply the primer evenly and undiluted once with a brush (apply more thickly to porous substrate materials).

On surfaces that may be slightly damp and very absorbent, longer drying times must be allowed for until the adhesive film becomes surface dry. Surface contamination of the exposed adhesive film must be avoided. Apply the butyl primer only as wide as matches the required adhesive width of the butyl tape being applied. The flash-off time (physical drying) of the applied adhesive layer depends on the thickness of the layer and the ambient temperature and is approx. 10 minutes at 20°C. Only then should the respective butyl tape be attached. When used indoors, adequate ventilation must be ensured.
