About this item
  • IDEAL FOR USE IN HIGH-MOVING JOINTS – The flexible and non-slump formula means it can be used in joints up to 50mm wide where there's a chance of expansion, such as pointing around doors and windows.
  • INCREASED TOOLING TIME – It has a long skinning time of between 30 and 45 minutes, which gives you more time to smooth and create a professional finish.
  • SUITABLE FOR EXTERNAL USE – Once cured, it is completely weatherproof with excellent UV resistance, meaning you can use it as an external sealant.
  • MULTIPURPOSE – The neutral cure sealant adheres well to a wide range of materials, including PVCu, plastic, copper, zinc, glazing, aluminium, masonry and more.
  • CERTIFIED – Conforms to ISO 11600 class F25LM and G25LM for low modulus, flexible sealants.
  • AVAILABLE IN A RANGE OF COLOURS: Available in anthracite, beige, black, brown, brick red, buff, dark anthracite, bark grey, limestone white, magnolia, mid-grey, Portland stone, and white.
  • REBRANDED – Previously known as Everbuild Tecnic 825.
Product description

Product Description Need to fill or seal an expansion joint between two different materials? Everbuild Tecnic 825 Silicone Sealant is a low modulus formula designed with a long skinning time to give you a longer tooling time and the flexibility you need to finish the job. It's neutral cure and odourless, so you can feel confident using it indoors, and it's weatherproof for external use, as well. The adhesion is top tier as it suits both porous and non-porous surfaces, including brick, PVCu, glass and more. Simply clean the surfaces, check the joint width is no larger than 50mm wide and 25mm deep, and apply. Also available a range of colours.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
