The Densostrip™ Primer is a fast-drying bitumen-based primer designed for joint surfaces before applying Densostrip™ flexible jointing compound. It is mainly used with precast concrete units, where proper surface preparation helps the Densostrip compound form a durable, flexible and watertight joint seal. Nassguard supplies Densostrip Primer in Riyadh and across Saudi Arabia, including Dammam, Jubail, Jeddah and Al Khobar.
Densostrip Primer is a fast-drying bitumen primer developed for use before installing Densostrip flexible jointing compound. The primer prepares the joint surfaces and provides the required base for the Densostrip sealing material.
The product is specifically intended for precast concrete units. Denso’s technical data sheet states that joint surfaces should be undamaged, clean and dry, with wire brushing used to remove dust, dirt and loose material before primer application.
When used with Densostrip, the primer forms part of a joint-sealing system for applications such as precast concrete pipes, box culverts, manholes, inspection chambers, tunnels and shafts. Denso states that its Densostrip system provides a permanently flexible and watertight seal when the compound is compressed between appropriately primed joint faces.
The Densostrip Primer provides a simple surface-preparation step before applying the Densostrip flexible jointing compound.
Densostrip Primer is used where precast concrete joints require preparation before installing the Densostrip flexible sealing compound.
The primer creates a suitable bitumen-based prepared surface before the Densostrip flexible jointing compound is installed.
Workers first clean the joint surfaces and remove dust, dirt and loose material. Denso recommends wire brushing for this preparation. The surface should remain undamaged, clean and dry.
Workers then apply one coat by brush and allow the primer to dry. The technical data sheet gives a typical drying time of 10–20 minutes. After the primer reaches the required condition, workers can apply Densostrip according to the relevant installation procedure.
Correct preparation helps the Densostrip system achieve effective contact with the concrete joint surfaces.
Densostrip Primer forms part of the Densostrip external concrete joint sealing system. The system combines a fast-drying bitumen primer with a sealing material designed to provide a flexible barrier at precast concrete joints.
Denso describes Densostrip as a rubber/bitumen compound in strip form. When compressed between appropriately primed joint faces, it forms a flexible, watertight seal. The system is designed to help prevent backfill infiltration through external joints.
Denso also states that when Densostrip and Densostrip Primer are used together, the system meets the requirements of BS EN 1917:2002 for concrete manholes and inspection chambers. Denso’s product information also lists compliance with the CESWI Civil Engineering Specification for the Water Industry, 7th Edition, and Sewers for Adoption, 5th Edition for the applicable Densostrip system.
Densostrip Primer is available in 5 L and 25 L drums. Denso recommends storing the product upright in its original packaging in a cool, dry area.
The primer has a stated flash point above 23°C, so workers should keep it away from heat, sparks and open flames. Follow the applicable safety data sheet and workplace procedures during storage, handling and application.
