• Resistant to salt solutions
• Resistant to most alkali solutions
• Resistant to most acid solutions
• Resistant to most alcohols, petrol, oils, fats

Cellular PVC may expand or contract due to changes in temperature. You should allow for this movement when fastening Rajvi PVC foam board/sheet.

Any product that is acrylic or urethane based will adhere to Rajvi PVC foam board/sheet. Common fillers, caulks and exterior grade spackle with titanium dioxide work well. Be sure to use a filler that is a good match to the white color of Products should you decide not to paint.

Nails: Use corrosion-resistant, smooth-shank, screw, annular-threaded or spiral type nails, and long enough to penetrate substrate by at least 3.8cm (1.5"). AVOID large-head nails and ring-shank nails due to excessive...

For longer lengths of foam boards/sheet, begin at one end and work to other end or at middle and fasten outwards. NEVER fasten from both ends toward the middle, which can create stress and expansion problems. Fasten at 40cm(16") intervals along the length, and keep nails and screws a...

To prevent joint separation of any foam, fill all joints (whether butted tight or with a gap) with a urethane acrylic sealant (which expands and contracts at the same rate as the product). When sealing a butt joint, apply sealant only to one butt end,

Amount of gap required depends on various factors; the length of piece (a piece of foam board or sheet) being installed, the overall range of temperatures experienced over the year, exposure to the sun, and the temperature at the time of installation.

• - Contact adhesives using synthetic rubbers (such as Neoprene based systems)
• - Adhesives films
• - Pressure sensitive adhesive tape

Rajvi pvc sheets and section can be manipulated using any of the above fixing methods. Like most thermoplastic materials, the influence of thermal expansion must be taken into account. To ensure that dimensional changes relative to ambient temperature are calculated at the fixing stage.
