Wood impregnator is a versatile treatment designed to protect both internal and external timber. Internally, it is commonly applied to loft rafters and roof timbers to help reduce moisture absorption caused by condensation within roof spaces, supporting long-term timber health. Externally, it can be used on garden decking and other exposed timber, where it causes water to bead on the surface and run off, helping to protect against moisture-related wear. In both applications, the treatment remains breathable, allowing moisture vapour to escape while helping preserve the strength, appearance and condition of the wood.
