Vulkem Sealing Primer 171
Key Benefits Summary
Ease of Application
A fast drying liquid that seals cementitious, plywood and other porous surfaces and imparts a surface finish which is very receptive to urethane sealants and coatings.
To prepare surfaces for the adhesion of urethane sealants and coatings, and to assure a water resistant bond on porous substrates. Vulkem Primer 171 is required for sealants and coatings subjected to immersion service.
Vulkem Primer 171 is reactive with moisture. Keep containers sealed until ready for use. Resealed containers have limited shelf life.
This product is amber in colour and is noticeable on some surfaces, so care must be taken to apply only to areas that will be covered by final products.
Vulkem Primer 171 should be applied by spray, clean brush or roller to a clean, dry surface free of contaminants. Use with adequate ventilation. Application rate will be determined by surface texture and porosity. For assistance, contact your Tremco consultant.
The following rates may be used as guidelines;
For smooth plywood, sanded fibreglass or bright abraded steel, apply at 7.3m2 - 9.7m2/L.
To reinforce adhesion on smooth concrete, rates of 8.5m2 - 9.7m2/L are effective. For rough or porous concrete or under split-slab membranes, rates are 2.4m2/L. Consult a Tremco Representative when used on non vented decks.
Vulkem Primer 171 will dry in 30-60 minutes, though may remain slightly tacky. If over 6 hours has elapsed, the surface should be primed with Vulkem Primer 191.
