Will you take the ecoSEAL challenge?

With the help of a number of well-known faces from across the construction industry we have launched the ecoSEAL Challenge.

Part of a six-month campaign to encourage those in the trade to reduce their plastic waste, we’re offering you the chance to try the innovative ecoSEAL system yourself – for free! 

A number of trade influencers have already taken the challenge, including Julian Perryman, Roger Bisby and Wayne De Wet. See what they had to say about the product and then sign up to give it a try.

If you would like to try ecoSEAL for yourself, all you need to do is fill out the form below and we will send you the products to try. You will be able to choose from Painters Mate, DOWSIL ecoSEAL 785+, DOWSIL ecoSEAL 796, DOWSIL ecoSEAL 799 or Geocel ecoSEAL THE WORKS PRO Sealant & Adhesive – and you’ll also receive a free ecoSEAL sleeve.

Once received, film your own product review and share it to our social media channels for a chance to win a £500 voucher. We’ll be selecting a new winner every month.


Our ecoSEAL sleeve can be used an average of 75 times and can be recycled at the end of its usable lifespan. In addition, once empty, all of our ecoSEAL foils are eight times smaller than traditional cartridges, meaning less waste is sent to landfill, ultimately reducing disposal costs on larger projects.


Currently available in foils are:
