FAQs
What is the main benefit of the 700T silicone sealant?
Its main benefit is its high flexibility (25% movement capability) and superior adhesion to a wide range of surfaces without the need for priming, combined with excellent weather resistance.
Can this sealant be used on UPVC window frames?
Yes, the Everbuild Everflex 700T is ideal for sealing UPVC window frames due to its good adhesion to plastics and its weatherproof properties.
How long does it take for the sealant to cure?
The sealant typically skins over in about 20-30 minutes and fully cures in approximately 24 hours, though this can vary depending on temperature, humidity, and bead size.
Is this sealant suitable for exterior use?
Yes, it is suitable for both internal and external use and offers excellent weatherproof and UV resistance.
Can I paint over this silicone sealant?
Silicone sealants are generally not paintable. For areas that need painting, consider using a non-silicone sealant like Everbuild's 450 or 705 range.
What does 'neutral cure' mean?
Neutral cure means the sealant releases a non-acidic vapour (alcohol-based) as it cures, making it safe for use on sensitive materials like metals and plastics without causing corrosion or damage.
How should I clean up uncured sealant?
Uncured sealant can be wiped away with a damp cloth. For more stubborn residue, a suitable solvent might be needed, but always test first.
Troubleshooting
Sealant not adhering properly
Ensure surfaces are clean, dry, and free from dust, grease, or old sealant. For porous surfaces, a primer may be beneficial, though typically not required for this product.
Sealant is skinning too quickly in the cartridge
Ensure the nozzle is securely sealed after use. Store the cartridge upright in a cool, dry place.
Difficulty achieving a smooth finish
Tool the sealant immediately after application using a damp finishing tool or cloth. Practice on a scrap piece to get a feel for the product's workability.
Sealant appears weak or crumbly after curing
This may indicate application in temperatures outside the recommended range or inadequate surface preparation. Ensure application within the specified temperature range and that surfaces are suitable.
