This Buff 380ml cartridge of Everbuild Tecnic Silicone 825 offers a warm, neutral tone that blends seamlessly with sandstone, light brickwork, limestone and beige building materials. The buff colour is particularly popular for heritage restoration projects and traditional building applications where a natural, unobtrusive finish is required. As a low modulus, neutral curing silicone sealant based on a filled alkoxy curing system, this product is specially formulated to provide extra tool downtime on longer joints. It excels at expansion joints to stone, brick, concrete and composite panels, perimeter pointing around window and door frames, and weather sealing for external applications. Features and Benefits: • Buff colour ideal for matching natural stone and traditional brickwork • Low modulus formula accommodates building movement without cracking • Extended tooling time allows for neat finishing on longer joints • Conforms to ISO11600 class F25LM and G25LM standards • Neutral cure system won't corrode metals or stain substrates • 380ml cartridge compatible with standard sealant application guns *Nozzle NOT included* Specifications: Colour: Buff Size (ml): 380

It’s a lot paler colour than the name suggests, it’s more of a cream colour than buff.

Works well

Easy to apply but harder to get a smooth surface than using ordinary silicone. Blends well with the coping joints and goes a long way too. Now I just need something else to seal before the remains go off!

Highly recommend, used in new build construction

Great tooling ability, nozzle can fill large perimeters fast, tube goes a long way, would be great if toolstation stock the fullbcolour range. Since changed its name to Sika 825 incase anyone gets confused when ordering

Good quality sealant.

This product is the best I've used, it's the perfect consistancy and sticks without dragging off the surface meaning a good finish. I used this for a brick expansion joint and should be ideal due to the flexibility stated in the data.

No quibble exchange of incorrect product

The first sealant tube was approx’ 2” too long for a standard calking gun, but there was no problem with changing it at the St Helens branch where the sales assistant was as always very helpful. 1 star for the first product, but 5 stars for the replacement

Shocking
