Gripset Xpress Primer H2O Plus is perfect for use on various surfaces, including concrete, masonry surfaces, renders, screeds, concrete blocks, aerated concrete, cement sheeting, plasterboard, general wet area linings, and other absorbent surfaces.

Application and Coverage:

Apply 1 x coat at a coverage of 1 litre per 6-8m². You can apply it by brush, short/medium nap roller, or airless spray. Before application, check the surface porosity with a water droplet test. If droplets do not absorb, prepare the non-porous surface by grinding, etching, or other abrasive means to open surface pores. The primer can be overcoated once the film is clear and tack-free. Coverage may vary due to the porosity of the substrate.

Storage Conditions:

Store Gripset Xpress Primer H2O Plus at room temperature and avoid cold freezing conditions and off concrete floors. Do not store it in direct sunlight. The shelf life is 12 months in an unopened container.

Clean Up:

Clean up the primer with water while wet. Once dried, the product needs to be removed mechanically or by using a solvent.
