Description
The 825 silicone comes in limestone white, white, black, mid-grey, brick red, brown, buff, anthracite, magnolia, portland stone, dark grey and dark anthracite.
PVCu/wood/powder-coated aluminium can be sealed internally and externally with this sealant. It seals and adheres to PVCu, plastic trims and components, and also soft metals like lead, copper and zinc. From weather sealing and joint sealing to pre-formed panels and curtain walling, glazing sealing and draught-proofing and much more.
The density of this product is 1.33 – 1.37g/cm3. Everbuild recommends storing the product in original unopened containers between +5°C and +30°C. Storage
outside these parameters may dramatically reduce shelf life.
Using a Primer with 825
On most common surfaces, 825 does not require a primer, but adhesion tests should be conducted before full-scale application. SIKAFLEX PRIMER 3N or EVERBUILD SILICONE PRIMER P1 should be used if the joint will be immersed or adhesion is poor (especially on porous surfaces). If necessary, prime non-porous surfaces with Sika Aktivator 205 or EVERBUILD SILICONE PRIMER NP2 (recommended for aluminium).
