Deltatorch Primer

Primary Coating for Waterproofing Membrane


Deltatorch Primer is a bituminous liquid that seals porous surfaces, such as concrete and when used improves the adhesion of bituminous materials that are to be applied to the substrate. Deltatorch Primer is the primary material for waterproofing membrane, made of polymer materials of high quality asphalt.


Use in well ventilated areas, avoid inhaling, do not smoke or allow sparks or naked light where stored or in use. Can also be applied in new constructions and the renewal works.


  • Can fill the pores on the surface of the concrete so that the waterproofing membrane can be attached to the surface very well with the existing base.
  • Can be used for all types of asphalt-based waterproofing membrane.





Deltatorch Primer should be thoroughly stirred before use and applied to the substrate by means of brush, roller or spray, at the rate of 300 gms/m2 for brush / roller application and 200 gms/m2 for spray application.


The area to be treated should be free from grease, oil, dust etc. Concrete should be cured and at least eight days old. After drying any localized discolouration of the surface should be retreated and allowed to cure.

Only primer areas that are to be covered in one day. Do not leave the primer exposed for more than 24 hours. If this should be the case, apply a further coat and allow to cure as above.

Tools may be cleaned with white spirit of paraffin.


2 hours + 1 hour depends on local weather conditions at the time of application.
