Application Description 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. Finishing: • Check the depth and width of the crack and choose the right filler • For Worm crack, use a cutter to widen the same and use 20MM Crack Filler • For hairline crack which is not very deep, widen it with the V groove blade and use 5MM Crack Filler • For cracks around doors and window frames which have varying widths, from hairline to 10MM, use 10 MM crack filler • Thoroughly apply Dulux Aquatech Crack Filler such that it penetrates the surface & level off using a putty knife. • Press the Crack Filler firmly into the crack to ensure full contact with the surface and level the surface properly. • Fill properly and care should be taken to avoid any air pockets or void formation. • Sponge the surface after the sample is touch dry condition to remove any excess of materials adhering to the sides of the cracks. • Leave the surface for drying for at least 3-4 hours. • Protect repair from rain and frost until completely dry. • Paint the surface with further systems as required as per normal painting application practice for interior and exterior surfaces. • Clean the application tools with warm water.
