Has your exterior wood been pre-treated by the manufacturer?

Promotion: Get FREE Sample Pots when you buy our Wood Preserver ++

If you are installing a new log cabin, summerhouse, or garden office, how is it protected? In the UK’s wonderfully varied climate your outside wood needs to be protected from the wet weather, rot fungi and possible attack by wood boring insects. Some buildings come pressure treated, this is a process where preservatives are forced into the timber under high pressure, after all the air from the timber’s cells has been vacuumed out. This leaves long-lasting protection against rot and decay. Pressure treated timber is usually a light greenish/brown colour and your building suppliers will say if it comes treated this way.


Some buildings come untreated, if this is the case we recommend applying our Wood Preserver ++ as a primer to any of our great top-coats that will add colour and weather protection. In fact, many of the UKs top timber building suppliers, that have used Protek for many years, recommend that you do just that.

Add Wood Preserver ++ to your basket then choose your free sample pot(s) these will be discounted at the checkout for you.

Some buildings come untreated, if this is the case we recommend applying our Wood Preserver ++ before applying one of our top coats.

If No, WHY Wood Preserver ++?
All our products offer great protection for your wood, but they are not classified as wood preservatives. Under very strict legislation governing wood preservatives these products must not only have minimum impact on their environment they must be effective. If your wood has been treated with a wood preservative, it will protect it from rot and prolong its life.


Our Wood Preserver ++ is a highly effective wood preservative that is water-based with low VOCs and odourless when dry. It is effective against moulds, wood destroying and wood discolouring fungi as well as against wood boring insects. It has excellent penetration into the layers of the wood and leaves an adhesive surface ready for our top coats.


So is my timber now fully protected?
No, you also need to protect it from the weather with a top coat.
