How to use
Renovate old or deteriorated drains and sewers from DN32-300 (1¼-12") diameter with the Picote Xpress Coating System. The coating applied provides a corrosion resistant, wear-resistant and non-corrosive lining. Several coats can be applied within the same pipe. Renovate entire piping systems for example apartments or blocks of flats with minimal disruption, avoiding costly excavation. Suitable for internal renovations and external projects such as waterspouts/downpipes, pool lines etc.
This product has been created to renovate drains, sewers, water pipes, electrical conduits, heat and a/c ducts and more in concrete, PVC, fiberglass, clay, copper, cast iron, ductile iron, and steel pipes by brush casting a coating. The specially formulated coating resin forms a corrosion resistant or semi-structural repair inside the original pipe (depending on # of coats applied) that is a tested, safe and environmentally friendly product. The new pipe is corrosion resistant, anti-static, wear-resistant and non-corrosive. Thanks to a high breaking stretch, it also withstands shocks and bending.
USES/BASIC METHODOLOGY:
• Extend the life span of the original pipe: The resin can be used to prolong the life of an existing pipe. Clean the pipe well. Apply 2 or more (1mm/coat) layers of the Xpress resin.
• The new slick inner surface will increase the flow inside the pipe minimizing the risk of blockages.
• Create a new semi-structural pipe: Apply multiple coats of the resin (use design calculator based on pipe diameter found in the manual or later in this document) to form a seamless new pipe with a 2-4mm wall thickness depending on the pipe diameter. Estimated 30-50 year design life when using Semi-Structural Design Specifications based on pipe diameter.
BENEFITS FOR CONTRACTORS: Extend the service life of a pipe, stop corrosion, create a new pipe, ”patch” on top of CIPP liners and fortify connections*. Apply to small areas or all drains in multi-story buildings. The Picote Coating affordable, practical and easily fits in tight places.
BENEFITS FOR PROPERTY OWNERS: System is Customers can stay at home or keep business open during drain renovation. A greener alternative eliminating the need to destroy existing walls, gardens or sidewalks, the no-dig solution reduces waste produced at job sites. Interruptions to traffic are also minimized. All materials used are non-toxic.
HOW LONG WILL THE PIPE BE OUT OF SERVICE?: Dry to touch in 3 hours with ambient cure. Return to Service/Light Wear: 4 hours. Final Hardness: 24 hours. Full service can be restored 4 hours after last coat has been applied (24hrs for potable)
TYPES OF PIPE: Suitable for concrete, PVC, fiberglass, clay, copper, cast iron, ductile iron, and steel pipes. Preparation of the coating surface is dependent on the material of the pipe. Please see corresponding Picote Operation & Safety Manual.
*Ensure that materials are compatible and the surface is properly prepared
