SANDROPLAST Bitumen Primer

SANDROPLAST Bitumen Primer

Product Type

Water-thinnable, solvent-free, and low-odor coating based on bitumen

Application Area

Priming agent with good adhesion and deep anchoring for subsequent hot or cold liquid adhesive coats, topcoats, and coatings on bitumen-based surfaces as well as for bitumen membranes. Can be used as a primer in the field of building waterproofing, roof waterproofing, suitable for all common mineral substrates as well as substrates with residual bitumen coatings and bitumen roofing membranes. Sandroplast Bitumen Primer itself has no sealing effect.

Properties

In its composition, the product meets the requirements of DIN 18 195 Part 2 Table 41 No. 2 and AIB DS 835 Appendix II Column 3. Sandroplast Bitumen Primer is quick-drying and exhibits excellent adhesion to the substrate, dust-dry according to DIN 18 195 Part 2 in approximately 3 hours.

Substrate

All substrates must be firm, load-bearing, and free of separating substances such as release agents, dust, dirt, etc. The surface is checked by wiping and scratching. When wiping by hand over the substrate, no components should loosen from the substrate, nor should the hand become soiled. Scratching is used to detect paint layers or hollows in otherwise solid substrates. Paint layers and hollows must be properly removed. The substrate must be free of burrs or sharp-edged unevenness such as mortar, concrete overspray, or stone protrusions. The surface must be visually inspected. Overhanging edges and depressions should be removed. The substrate must be rough and absorbent. Solvent-based bitumen coatings require a dry substrate. The primer must be sufficiently dry or ventilated before applying subsequent layers.

Application

Sandroplast Bitumen Primer is applied by brushing, rolling, or spraying.

Note

Freshly applied coating may be foamed or washed off during heavy rain. FOR EXTERNAL USE ONLY.
