Surface Preparation:
• Widen the grooves to make a V shaped surface.
• For the Interior surfaces, existing POP or putty must be removed till the plaster surface is exposed.
• Ensure the groove is thoroughly clean, dry and free from all loose dirt, chalk, grease, fungi, algae and flaking paint. This can be achieved by brushing with a wire/stiff coir brush, followed by water jetting if required and use the Dulux Aquatech Pre Treatment Coat to clean up the fungal infested walls.
• Treatments such as sanding, burning off etc. of paint films may generate hazardous dust and/or fumes. Wet sanding/ flatting should be used wherever possible. Work in well ventilated areas. Use suitable personal protection equipment
• If after thoroughly cleaning the surface, the surface still exhibits chalkiness, the surface should be coated with Dulux Exterior Acrylic primer for exterior surfaces or Interior Acrylic primer for interior surfaces.
