Cold Applied, High Performance, Pitch Free, Polyurethane Pavement Joint Sealant
Estoseal C200PF cold applied, two part elastomeric sealant is design for joints in concrete paved areas.
It cures to form a durable and elastic seal, particularly suitable for areas where fuel and chemical spillage may occur. Estoseal C200PF has outstanding resistance to UV weathering and commonly occurring chemicals.
For sealing movement joints in:
Joints should be designed so that the total movement due to concrete shrinkage and thermal changes does not exceed the 25% movement accommodation factor related to the joint width. The sealant depth should not exceed joint width. All joints subject to traffic shall be recessed 3 – 5mm below flush, so that during joint contraction the sealant does not protrude above the surface.
Joints up to 12mm width should be the same depth as width, joints above 12mm should maintain a 2:1 width to depth ratio, subject to a minimum depth of 20mm for trafficked joint or joints under hydrostatic head.

Joints should be very clean and dry. Remove all dust, dirt, loose particles and contaminants and wire brush thoroughly or preferably grit blast the joint interfaces. Install Estop Backer Rod to avoid 3 sided adhesions.
Mix Estop Primer S9 Base and Hardener and prime the joint interfaces for porous substrates. A single coat of primer applied by brush must be allowed to dry minimum period of 1 hour before applying Estoseal C200PF. Any primed areas left more than 3 hours must be re-primed before sealant application.
Mix and use one complete kit at a time. Both components shall be thoroughly mixed. It is recommended to mix with an electric drill (300
– 400 rpm) with a flat bladed paddle for a minimum of 3 minutes. Ensure that both the components are mixed evenly. Immediately after mixing, pouring grade Estoseal C200PF can be poured directly from the tin into wider joints or into a sealant gun for application.
For use and application of joint sealants for concrete pavements, please refer to BS 5212 : Part 2 : 1990.
Estoseal C200PF with Estop Primer S9 is not compatible with bituminous surfaces.
