- Resistant to UV, chemicals, oil, diesel and petrol
- Easy to install, cost effective joint waterproofing solution
- Can be applied to damp or dry substrates
Apply mixed Silcor® Epoxy adhesive to substrate both sides of the joint with a spatula to a thickness of 1mm to 2mm.Ensure the adhesive application is a minimum 25mm wider than the FLEXIBLE SEALING TAPE strip. Minimum width of adhesive on either side of the joint should be 50mm. On damp surfaces, ensure the adhesive is well worked into the concrete to allow bond to develop.Place cleaned FLEXIBLE SEALING TAPE strip into the adhesive, with central tape facing away from the joint. Roll the strip into the adhesive ensuring all trapped air is removed and adhesive seeps through perforations at edges of the strip. Where joint movement exceeds 25% of the joint width, form a “loop” in the FLEXIBLE SEALING TAPE of sufficient size to accommodate the extent of movement (contact your local GCP representative for further guidance). Where possible, the loop should protrude above the joint, not into the joint, to avoid pinch damage with joint movement.

SILCOR Primer BS is used for substrates with maximum moisture content of 5%. For moisture content less than 10%, use SILCOR Primer BW Clear/EPOCOTE F100W Clear.
Apply one coat directly from container using brush, roller or spray. Allow primer coating to become tack-free before applying waterproof membrane. Only apply primer to substrate that will be membrane coated within 24 hours.
Apply the selected SILCOR polyurethane waterproofing product in strict accordance with product instructions.
Any primed area not coated with membrane within 24 hours must be first wiped with Xylene. As soon as xylene has dried, reprime with a light coat of SILCOR Primer BS at a rate of approximately 0.15kg/m2. Any applied primer that has not been coated with membrane within 72 hours of application, must be fully removed by diamond grinding and re-primed.
What is SILCOR® liquid waterproofing?
SILCOR® is a high performing seamless, liquid waterproofing system for podium decks, green roofs and terraces. Based on advanced chemistries, SILCOR products are fully adhered, elastomeric waterproofing barriers offering design and application flexibility through spray as well as squeegee application.
Design flexibility with waterproofing confidence
For architects, SILCOR® liquid waterproofing removes several constraints. SILCOR® is truly seamless and will conform to nearly any surface. As such, SILCOR® will accommodate almost any design without compromising waterproofing performance, while being fully compatible with GCP's other waterproofing products and air barrier solutions.
Build faster without sacrificing water protection
SILCOR® liquid waterproofing also proves its usefulness on the job site. There's no longer any need to halt construction due to strong odours or an obstructed surface. Most importantly, SILCOR® is applied without the need for kettles, propane or open flames. SILCOR® liquid waterproofing lets builders instal waterproofing safely and without calling a halt to other construction.
Backed by a world-class reputation
When it's time to invest in waterproofing, invest in a proven technology that comes from one of the world's most trusted manufacturers. GCP has been in the liquid waterproofing business for more than 20 years. SILCOR® liquid waterproofing has been used in projects ranging from Pruva 34 in Istanbul to Crossrail in London.
Finally, GCP offers a technical services and consultation platform that's second to none. Contact GCP for information on the specific products within the SILCOR® portfolio that are best for your building or project.
