Made in the UK with pride

Where it all began

Protek is a family owned and run manufacturing business based in the Mendip Hills in Somerset.  

The business was set up by Eric and Janet Thornborough in 1983 with a vision to sell quality water-based wood stains, decorative timber coatings and preservatives.  They developed products that gave good coverage, were effective and long lasting, yet were kind to the environment.  

Today the business is run by their two daughters, Becky and Harriet, who are fiercely proud of Protek and all it stands for.  


The Environment 
For almost 40 years Protek have been thinking about the environment. 
Whilst everyone else was using harsh and toxic chemicals, such as creosote Protek developed a range using only water-based technology.  
Four years ago, Protek decided to move all of their packaging to metal tins, that could be recycled or even reused.  Where this wasn’t possible they sourced recyclable plastic buckets. 


Colour charts are created as a guide for colour selection and if you need to know exactly what colour a stain will produce on your timber product, sample pots are available for all colours in all of the ranges.



What has changed since 1983
The biggest change is colour.  
When Protek started there was a choice of browns and greens.  Today there are over 100 colours to choose from on trend blacks and anthracite greys to the subtle greens and blues. 

Protek are delighted to be finalists in the Albert Goodman Family Business of the Year category as part of the Somerset Business Awards 2022.
