Start by sanding your wooden shed with a 150/180 grit sandpaper. Make sure to wipe off any dirt, residue and resin between one board and another with a dusting brush and a dry cotton or microfiber cloth.
Now you need to use the IMV impregnating agent! This product, available in different colors, from gray to brown, protects well the wood surface, penetrating into its pores. Our tip: when opening the can, mix the product well for at least one minute to reduce its high density.
The application of the IMV wax-like metallic water-based impregnating agent is a key step. Follow the wood grains along the boards, paying special attention to hidden parts and intersections. Once applied the first coat, wait at least 1-2 hours before proceeding with the second coat.
