• Apply with a roller, brush or spray


Preparation of surfaces for applying PolyureCoat

Ensure all surfaces to be waterproofed are thoroughly cleaned, dry and free of any rust, mould or contaminants such as oil or grease. Loose stone chippings must be removed and any cracks and splits with the substrates made good prior to the application of the system. For all applications to concrete or single ply systems please contact Easy Trim Technical department for further information.


Application of PolyureCoat

Work out the area to be covered by each tin before commencing the application. Apply the accelerated product using a roller, in a single coat application, at a nominal rate of 1.7kg/sqm min. over the entire main field area.

Upstands, joints and de-bonded laps must be reinforced using the Easy-Trim GFR 225 in a wet-wet application. Apply a coat of Polyurecoat at 1.5kg/m2 over the upstand, joint (ply or OSB deck joints must be tapped over) into which bed the Easy-Trim GFR 225 (available in 150mm and 250mm widths). Pull through the Polyurecoat using a roller or brush across the matting, add a further 0.25kg/m2 whilst still wet to fully encapsulate the GFR matting. Ensure this detail is continued on all the upstands.

The curing time of accelerated Polyurecoat is rapid, so ensure the required application standard is achieved before moving on. The whole roof area must be coated in Polyurecoat at the specified coverage rate for full product guarantee. When applied without the accelerator, Polyurecoat must be applied in 2 thin coats with a coverage rate of no more than 0.8kg/m2/coat.

Mixing: Mix the product for about 2 mins before adding the accelerator. Carefully pour the accelerator into the tin of Polyurecoat and slowly mix with a paddle mixer at slow speed until the accelerator is visibly mixed with Polyurecoat.

Mix the accelerator at the exact same ratio as supplied with the Polyurecoat. Not adhering to the prescribed ration could lead to incorrect mix and the product not curing correctly.
