The Everbuild 700T Contract Silicone in White is designed for trade professionals and DIYers needing a reliable sealant for PVCu and roofline applications. Its key benefit is a fast, neutral cure and excellent mould resistance, ensuring a durable and clean finish. A potential caveat is its specific formulation for exterior applications, meaning it may not be the ideal choice for all interior sealing needs.

It is specially formulated for the PVCu and roofline industry, ideal for perimeter pointing of window and door frames, sealing plastic roofline areas, and general weather sealing.
While its mould resistance can be beneficial, it's primarily designed for exterior applications. For interior wet areas, specific interior-grade silicones might offer a better aesthetic or performance profile.
The cure time can vary depending on temperature, humidity, and bead thickness. Typically, it skins over in minutes and can be handled within a short period, but full cure may take 24 hours or more.
No, silicone sealants are generally not designed to be painted over. Painting may lead to poor adhesion and peeling. If painting is required, consider using a paintable sealant.
Wipe away any excess uncured sealant immediately with a damp cloth. For stubborn residue, use a cloth dampened with a suitable solvent, following safety precautions.
Acetoxy cure silicones release acetic acid (vinegar smell) as they cure and are good for general-purpose sealing. Neutral cure silicones, like the 700T, release alcohol or other non-acidic compounds, have low odor, and are often preferred for sensitive materials like PVCu and metals.
An unopened cartridge typically has a shelf life of 12-18 months when stored correctly in a cool, dry environment, away from direct sunlight and frost.
Ensure the cartridge is properly loaded into the gun and the release trigger is engaged. Check that the inner seal has been pierced.
Ensure the surface is clean, dry, and free from dust, grease, or old sealant. For porous surfaces, a primer may be necessary (consult product data).
Practice applying a consistent bead on a scrap piece of material. Ensure the nozzle is cut correctly for the desired bead size and maintain a steady speed and pressure with the cartridge gun. Smooth the bead immediately after application.
While the product resists mould, excessive moisture or inadequate ventilation in the area can still lead to mould. Address the underlying moisture issue and ensure proper airflow.
Setup:
This silicone sealant requires a standard cartridge gun for application. Cut the nozzle tip at a 45-degree angle to achieve the desired bead width. Pierce the inner seal of the cartridge before loading it into the gun.
Compatibility:
Everbuild 700T Contract Silicone is specifically formulated for use on PVCu, painted surfaces, brick, concrete, aluminium, glass, and other common building materials. It is suitable for perimeter pointing of window and door frames, sealing plastic roofline areas, and general weather sealing. It is not recommended for use on or adjacent to asphalt, bitumen, or certain plastics where it may cause staining or degradation. Always test on an inconspicuous area if unsure.
Care:
Store cartridges in a cool, dry place, away from direct sunlight and extreme temperatures. Once opened, ensure the nozzle is capped or sealed to prolong the product's shelf life. Clean up any excess uncured sealant immediately with a damp cloth or appropriate solvent (check product data sheet for specific recommendations). Cured silicone can be difficult to remove and may require mechanical means or specialized removers.
