Bitumen-rubber primer 18 kg Hydrostop Primer Sol Extra

The Hydrostop Primer Sol Extra is a rubber-modified bituminous compound designed for applying primers and creating independent waterproofing coatings.
The Hydrostop Primer Sol Extra (produced by Farbis) can be applied on dry or wet surfaces, offering strong adhesion to concrete, plaster, masonry, wood, metal, OSB, bituminous cardboard, or old bituminous coatings. Due to its solvent-based composition, Hydrostop Primer Sol Extra penetrates deeply into the porous base of the concrete, forming an insulating layer.
Together with Hydrostop Membrana Sol and Hydrostop Filler Sol, this primer from Farbis ensures a quick renovation and repair system for bituminous roofs and terraces, applied over the existing layer, reducing the risk of water infiltration and extending the lifespan of the existing coatings.
Before application, bring the product to room temperature, then mix it with a low-speed mixer. Apply the first layer, rubbing it into the surface with a brush or roller. For priming, apply a single layer, and for waterproofing, apply 2-3 layers using a brush, roller, or sprayer.
The complete drying time for the bitumen-rubber primer is 3 hours. Hydrostop Primer Sol Extra consumption from Farbis: 0.2-0.3 kg per m² per layer.
