Everbuild Tecnic Silicone 825 – Limestone White 380ml (Box of 25)

Uses

The Everbuild Tecnic Silicone 825 – Limestone White 380ml (Box of 25) is a unique, low modulus, high viscosity non-slump silicone. It provides fantastic adhesion, perfect for perimeter pointing internally and externally.

Not only does its incredible adhesion achieve perfect perimeter pointing, but it is also outstanding as a general adhesive. Everbuild's scientist brewed this product with amazing adhesive properties but also superb resistance to weathering and water. Application this product excels at include;

• Perimeter pointing internally and externally around wood, PVCu and powder-coated aluminium
• Used for sealing and as an adhesive onto PVCu, plastic trims and components.
• Ideal for sealing soft metals such as lead, copper and zinc
• Weather sealing and joint sealing to pre-formed panels and curtain walling, glazing sealing and draught proofing
• Suitable for glass-to-glass and glass to aluminium sealing. Parapet and roof weather sealing applications.
• Perfect for expansion joint sealing

Preparation

Clean all substrates thoroughly before starting the application. Remove all contaminants such as dirt, dust, oil, and grease to ensure strong adhesion. For large-scale projects, carry out preliminary compatibility tests between the product and the surface.

Some surfaces can be difficult to bond to, so follow these specific preparation steps:

• Glass, aluminium, light alloys, and stainless steel – Degrease with alcohol or MEK.

• Other metals – Lightly abrade the surface, then degrease with alcohol or MEK.

• Wood – Lightly abrade the surface and remove any dust.

• Plastics – Degrease using an agent recommended by the plastic manufacturer.

• Concrete and other alkaline surfaces – Brush the surface clean and remove all dust.

• PPCA – Clean the surface with a dedicated cleaner, then apply an activator.

Application

1. Cut the top of the cartridge, taking care not to damage the threaded screw
2. Cut the nozzle at a 45° angle to an opening which you require
3. Place the cartridge into a standard sealant applicator/gun
4. For adhesion, you should apply this to one surface and then bring the two together
5. For perimeter pointing, apply one continuous bead along the whole gap
6. Tools down using an applicator tool
7. When doing perimeter pointing, you should smooth the sealant before the skin starts to form

Limitations

• Do not use this in conjunction with bitumen, asphalt, neoprene and certain organic elastomers
• Do not use this in the manufacturing of aquariums
• This product is not suitable on surfaces that bleed oils or plasticisers
• Not recommended as a mirror adhesive
• Do not use it on food-grade applications.
