Osmo WR Base Coat 4001 is a clear oil based primer basecoat for use on external timber prior to finishing with an oil based finish such as Osmo UV Protection Oil.
It is extremely water repellent, penetrates deep in to the wood and prevents shrinkage or swelling.
Softwoods in particular require additional protection from water and insect damage.
Osmo WR Base Coat has a very low odour and is completely odourless when dry, it contains biocides and will protect against insect attack, rot and staining.
It is not a finish in its own right, always overcoat with a suitable external finish such as Osmo UV Protection Oil within 3 months.
The original Osmo Base Coat 4005 has now been replaced with this improved oil based 4001 version giving even better protection.
For an interior version of this product, please see the Osmo 4006 Wood Protector, the same excellent water repellent properties but without additional biocides.
