Many people wonder if they can paint their siding? The answer is yes and it is a relatively cheap way to update the exterior of your home to a more modern look. It is important to note that you must use a "vinyl safe" colour and product though. In the past, most deep colours were made with a black tint which absorbed the sun and caused vinyl to warp when painted. However, paint companies like Sherwin Williams and Dulux have create products and tints that will work on vinyl with deeper colours. Go by your local paint store to find out what colours and products can be used. The siding does need to be thoroughly washed with TSP to remove any direct and residue. Then the finish coat can be applied with brush and roller OR for a factory finish using a sprayer.
