No More Big Gaps Expanding Foam 390g

Selleys No More Big Gaps is an expanding foam, which cures into a semi rigid closed cell foam, making it ideal for filling large and irregular holes or cavities such as around pipes.

• Fast curing. Surface will be tack free within 15 minutes after application. A 3cm to 5cm deep application will be fully cured in approximately 4 hours.
• Expands up to 2.5 times to fill those irregular and large holes around the home. Expansion will vary depending on the conditions and confinement of the space.
• Excellent insulator, and also blocks pests, noise and birds.
• Convenient aerosol can, no mixing required simply spray into the gaps.
• Cured product can be cut, trimmed, sanded and painted.
• Temperature resistance – approximately -40oC +90oC.
• Suitable for interior and exterior use.
• Superior adhesion to a broad range of surfaces, resulting in a lasting finish.
• CFC-free ozone friendly hydrocarbon propellant.
• Use the gloves enclosed in the lid
• Full expansion is not immediate, so don’t overfill the hole.
• Clean up any overspray and spillage immediately while still wet using a dry cloth. Acetone/Nail polish remover will assist.
• Once cured, product can only be removed mechanically by sanding, grinding or
  scraping away.
• If you spray a small amount of moisture onto the surface, or wipe it with a wet rag, it will increase the expansion.
• If using the product outdoors, paint over the application to improve its durability.
• If a hole is greater than 5cm, apply once and allow the product to fully cure, which is approximately 4 hours and then apply for a second time. Allow each layer to fully cure before re-applying. Never apply more than 10cm per layer to allow for maximum expansion.
• Keep a pack of Selleys Sugar Soap Wipes handy to wipe up any spills and for cleaning. They are an easy and effective way to keep clean on the job.
• Note – Do not empty can in one continuous application. Product will not cure in a sealed space without water present. Shallow applications expand more than deep applications. Once cured, product can only be fully removed by sanding, grinding or scraping away. Do not apply below 5°C.
