Application

Make good cracks and structural defects. All surfaces must be clean, dry and free from algae, lichen & other growths. Any faults in the substrate/structure, particularly those that can lead to moisture penetration, must be rectified or can affect the finish quality. Any existing crazed or flaking paint, dirt, grease or other surface contaminants should be removed. For optimum performance apply to a substrate that has been primed with Wethertex ST1 Quick Dry Stabilising Primer. Scaffolding must be independently tied to allow for uninterrupted application.

Stir the product thoroughly and do not contaminate. For application by hawk and trowel apply to 1-2mm thick and texture using a High Build application roller, or other texturing rollers or tools. For spray application, prime all areas to be decorated. For best results in terms of finish, coverage, speed of application and low over spray the following set up is recommended. Use a GC 200/24 2HP compressor or larger that can continuously deliver a maximum of 80psi at 4-5 cubic feet per minute on a 3 metre (max) length air-line to the spray gun. A GC 330 hopper feed spray gun with a 3mm air cap and tip size of 3-4mm. Apply at 40psi air flow/spraying pressure with an 18” (450mm) distance from gun tip to the surface being coated. Cover areas not to be sprayed with masking tape and wet strength masking paper or film. Spray using a ‘cross hatch’ method, i.e. horizontally & vertically to achieve a full, uniform and even texture overall. Clean the tip and air cap frequently during use to prevent blocking. Apply all products in accordance with BS 6150: 2006 Code of Practice for painting of buildings and BS 8000: Part 12: 1989 Code of Practice for decorative wall coverings and painting.
