Product Information

Full details

The Evo-Stik Frame Silicone Sealant (Clear, 290ml) is designed for builders and DIY enthusiasts seeking a durable, weather-resistant seal for interior and exterior building applications, particularly around frames. Its key benefit is direct adhesion to various construction surfaces without priming, saving time. A caveat is its specific use case for frames and high movement joints, not general-purpose sealing.

FAQs

Can this sealant be painted over?

Silicone sealants, including the Evo-Stik Frame Silicone Sealant, are generally not paintable. Paint will not adhere well to the silicone surface.

What is the expected lifespan of the seal?

The product offers performance durability of up to 25 years in demanding environmental conditions.

Is this sealant suitable for use in bathrooms or kitchens?

While it offers weatherproofing, it is specifically formulated for frames and building joints. For wet areas like bathrooms and kitchens, consider a mold-resistant silicone sealant.

Do I need a special tool to apply it?

You will need a standard cartridge sealant gun for application. This is not typically included with the cartridge.

How long does it take to cure?

Tack-free within approximately 30 minutes and fully cured within 24-48 hours, depending on bead size and environmental conditions (temperature and humidity).

Can I use this sealant on exterior wood frames?

Yes, it is compatible with hardwood frames and provides lasting weatherproofing for exterior applications.

What is 'low modulus' and 'neutral cure'?

'Low modulus' means the sealant is very flexible and can accommodate significant joint movement. 'Neutral cure' indicates it releases a non-acidic vapor during curing, making it safe for use on most building materials without causing corrosion or damage.

Troubleshooting

Sealant is not dispensing from the gun.

Ensure the cartridge's inner seal is pierced and that the sealant gun's trigger mechanism is fully engaged with the cartridge plunger.

Poor adhesion to the surface.

Verify that the surface was clean, dry, and free from dust, grease, or previous coatings. Ensure the product was applied to suitable materials as per compatibility guidelines.

Uneven or messy sealant bead.

Practice applying a consistent bead on a scrap surface. Ensure the nozzle is cut correctly for the joint width and that the sealant gun is operated at a steady speed. Smooth the bead immediately after application.

Sealant remains tacky after extended curing time.

Ensure application occurred within the recommended temperature range and that excessive amounts were not applied in a single layer. In very humid conditions, cure times can be extended. Check the product's expiration date.

Setup, Compatibility & Care

Setup:

  1. Ensure the surface is clean, dry, and free from dust, grease, and loose material. Remove any old sealant or debris.
  2. Cut the nozzle at an angle to achieve the desired bead size. Pierce the inner seal of the cartridge.
  3. Load the cartridge into a standard sealant gun.
  4. Apply a consistent bead of sealant along the joint, holding the gun at a steady angle.
  5. Smooth the bead immediately using a wet finger, spatula, or smoothing tool for a neat finish.
  6. Clean up any excess sealant with a damp cloth before it cures.

Compatibility:

This silicone sealant is compatible with a wide range of building materials including:

  • Blockwork
  • Brick
  • Concrete
  • Masonry
  • Aluminium frames
  • Hardwood frames
  • uPVC frames

It is suitable for both interior and exterior applications.

Care:

Once cured, the sealant is low maintenance. Clean the sealed area gently with a damp cloth. Avoid using abrasive cleaners or solvents, as these can damage the cured silicone.
