PreparationIf it's an old wall, proper preparation is necessary to remove dirt, grease and dust. You can begin by washing the surface with water and detergent. Get rid of the moss, mildew, lichens and paint flaking patches. A power washer does a great job of cleaning pebbledash walls. Look at the wall thoroughly to make certain it doesn't have any defects. Use a filler to patch up cracks in the wall. In case of chalky or powdery walls, apply a stabilising primer for sealing.
First CoatApply the initial coat with a masonry brush. The Hamilton Performance Masonry Brush is an excellent choice due to its hard-wearing bristles. Start at the top, work downwards and around the edges. Ensure that the paint gets into the little undulations and pits. If it's a new build, be aware that the walls will suck in that first coat.
Second CoatFor the second coat, the Hamilton Perfection Extra Long Pile roller comes in handy. A long pile roller ensures that you get to parts of the wall that the brush couldn't reach. This stage is less challenging and may not take as much time as the first coat. The door frame, window sills and gutters are some of the areas that weather fast, so apply two or three coats around these sections.
Dedicate enough time to paint pebbledash exteriors because you have to be meticulous. A well-done paint job of a pebbledash exterior can last between 10 and 15 years. However, a painter must know the right techniques, tools and products to use for the best results.
