Product Description

Mapei Mapewall GPR is an easy to apply on suitably prepared masonry substrates general purpose render for internal and external use.

Best Uses

Mapei MapeWall GPR is suitable for rendering and levelling internal and external masonry substrates, in thickness's up to 15 mm per layer, up to a overall maximum thickness of 40 mm. MapeWall GPR is a grey powder composed of cement, selected aggregates and special synthetic resins, which when mixed with water provides a render that is easy to apply on suitably prepared masonry substrates. MapeWall GPR can be applied by hand or with a rendering spray machine.

Mapei MapeWall GPR enables surfaces to be finished in one of the products from the Mapei range of coatings. Mapei MapeWall GPR is ideal for smoothing walls, dubbing out mortar, render only with sponge finish and render only with silicone and mineral finishes.

Application

Preparing the substrate
The substrate must be compact, free of dust, oil, grease and paints. If in doubt please contact Promain's technical dept. MapeWall GPR can be applied to damp substrates; however the drying time will be extended. Highly absorbent or poorly keyed surfaces must be dampened down or a suitable primer applied.

Preparing the mix
MapeWall GPR should be mixed with clean water and stirred until smooth using a mechanical paddle mixer. MapeWall GPR is suitable for application with rendering spray machines. One 25 kg bag of MapeWall GPR should be mixed with between 5.0 and 5.5 litres of clean potable water and the mixed product remains usable for 1 to 3 hours.

Applying the mix
Apply by trowel or machine. Uneven substrates may require a first coat to build out the thickness required. Level off with a straight edge or darby. The system can be reinforced with Mapei Mapetherm Net to help prevent cracking.

It is inadvisable to apply in direct sunlight or when the temperature is below +5°C and falling or above +30°C. The render can be finished with products from the MAPEI range, allow sufficient drying time before application. This will be dependent upon relative humidity at the time of application.
