R coat 30-36, an aqueous solution is applied in conjunction with woven fiber Glass cloth spreading on the outer surface of insulated GI/Al, ducting, and chilled water piping to provide sealing against air and moisture mechanical impact and resistance to scratches for Indoor application, It is invariably, a must on SA ducting in the space above false ceiling through which return air is being drawn and non-conditioned spaces, chilled water piping, etc. in conjunction with a layer of woven fiberglass cloth It acts as cladding to the insulation material against environmentally hazardous like dust rain, moisture acid vapors, mechanical impacts, Chemicals, and Alkalies, etc. for outdoor application In both the indoor and outdoor application the surface should invariably be finished in two layers of R coat 30-36 over the insulation wrapped with woven fiberglass cloth Invariably an excellent water vapor barrier with low water vapor permeance. This system applies to all types of insulation materials. The product is classified as Class 1 in respect of the Surface Spread of Flame as per BS 476 Part 7.
Method Of Application
The insulation surface should be cleaned thoroughly.
Stir its contents well before use to have homogeneous material before use.
Apply a tack coat with a fully dipped brush and spread it evenly over the insulated surface.
Immediately wrap the Glass cloth smoothly on the wet coating Care should be taken such that the cloth is applied in tightened and straightened position without any wrinkles.
Overlap the seams by at least 50 mm, so no air pockets are formed.
Allow the surface to dry completely.
Apply two finish coats. The first coat must be dried completely before the second coat is applied. Allow the second coat to cure (dry) for a minimum of 24 hours at ambient temperature -30 C px.
Keep the container closed when not in use.
In case of special aesthetic appearance and matching architectural requirements, the last two finish coats, one with plain roller followed by laminated surface rollers fully dipped in both cases.
On an average of 1.5 m2/Kg/coats (with three coats)
