Excellent product
I used this on the exterior of my shed and was very pleased with the results. The shed looks almost new. Easy to apply and dries quickly. Repels rain water. Does darken the appearance of the wood

Excellent wood protection
8 years ago our house was built with an area of Siberian Larch wood cladding on the outer kitchen wall. We wanted to enhance the grain and retain the colour with additional future protection against UV light, weathering and mould, etc. Our builder initially used 2 coats of this product on the wood and recommended we re-treat it with one coat every 2 years in order to retain the wonderful colour and grain effect. As shown in the picture, it still looks as good as new after exposure to 8 years of Scottish weather. It is very easy to apply and dries quite quickly. The 750ml tin is sufficient for at least 3 applications in our case, so very good value for money. I highly recommend this product.

Impressed with this wood treatment.
Great item, quite expensive. The oil is easy to apply and the wood appears well protected now. Used on new and 50 year old wood.

Quality Woodstain
Perfect protective woodstain and colour for our farm gates. Water does not get in and beads on top. Would buy again.

Really great product, super fast shipping. Price was a little on the higher side for the quantity, but if I don't need to re apply every year than it's money well spent! Let's hope I don't need to do it again!
