How to use GRAVA Wall Primer Sealer No. 408

General surface requirements: The surface must be dry, able to absorb and bear load, neutral, clean and free of separation agents, cracks, efflorescences and fungi.

Preparation: Close holes and cracks with VEDO Wall Filler No. 440. Construction cracks must be repaired with a crack bridging repair system. The following summary contains information on pre-treatment for various surfa­ces, and when to use GRAVA Wall Primer Sealer No. 408. GRAVA Wall Primer Sealer No. 408 must be diluted enough so that there is no development of a film. Please test on site.

Surface Preparation
Cement, gypsum and lime plaster Remove dust and dirt. Sand the surface to remove powder coatings.
Concrete Remove oil residue, dust and dirt.
Breeze-block Remove dust and dirt. Use filler if necessary.
Clay, face masonry Remove dust and dirt.
Old, sound oil or latex paint Abrade the surface and remove dust, or wash the surface.
Old chalky paint Brush with a wire brush and remove dust.
Water-based or unsound old paint Remove completely, wash and dry.
Hardboard Remove any residual separation agents.
Gypsum board Check joints for fit and tightness.
Gypsum fibre board Check joints for fit and tightness.

Application: Stir concentrate well. Test applications! Depending on absorbency of the surface, dilute with 1-2 parts slightly warm water. Add water gradually while stirring. For highly absorbent surfaces such as clay, or lime plaster, use undiluted GRAVA Wall Primer Sealer No. 408, or slightly diluted with water (20 %).

Important tips: For surface preparation before wallpapering, apply a mixture of ready to use LAVO Natural Wallpaper Paste No. 535 and GRAVA Wall Primer Sealer No. 408 diluted with 20 % of water at a ratio of 1:1. Nicotine or water spots can be blocked out with REMIO Natural Stain Blocking Primer No. 618, chip-board, ply-wood, OSB-board, or material containing penetrating substances, need to be primed with Natural Stain Blocking Primer No. 618. When REMIO is used, it is not necessary to prime with GRAVA. In case of salt bleeding, a professional must be called in to specify and correct the problem before wall sealing can start. Possible separation of the product does not impair the technical quality.
