Features:
Select solvent allows for optimum penetration of TEGOLA Primer (S)-25 into the surface pores, pin holes, and cracks. Absorbs the existing dust and scale, thus the resulting surface permits the proper bonding of self-adhesive as well as torchable membranes, in addition to any other bituminous adhesives and coatings.
Application Method:
- The surface must be thoroughly cleaned, and all dust, dirt, loose coatings, oil, or greasy substances removed.
- Concrete must be completely cured and dried prior to priming.
- TEGOLA Primer (S)-25 should be allowed to dry completely before applying the subsequent coat/membrane.
- It can be applied with a roofing brush, roller, squeegee, or airless spray equipment at the recommended coverage rate.
Safety Guidelines:
Flammable: contains petroleum distillate. Keep away from open fire, sparks, or other ignition sources. Wear protective clothing, gloves, and goggles during application.
Skin - Avoid repeated or prolonged contact. However, if it occurs, remove it with a hand cleaner that removes oil or grease, then clean with soap and water.
Eyes - Contact could cause irritation. If contact occurs, flush immediately with clean water.
Inhalation - Can cause dizziness. Move to fresh air. If dizziness and breathing difficulty persist, administer oxygen and contact a physician.
