Fire Test or Assessment Reports

BS476 Part 20 : EN1366-4

Health and Safety

The product does not present any known health hazards during or after installation. Normal good industrial and personal hygiene practices should be observed.

Installation

Always carry out a test to confirm compatibility prior to use. As with all PU foams, it does not bond to polythene, Teflon®, siliconised or wax-like surfaces.

• Protect floor coverings with paper or a plastic film.
• The surfaces must be dry, solid and stable.
• Remove all loose particles, dust and grease.
• A speedier cure can be attained by moistening the substrates if needed.

Shake the canister vigorously at least 20 times.

Remove the protective cap and screw canister onto a PU foam gun.

Direct foam into gap, pressing gently on the trigger to establish the correct flow rate.

Joints should be under-filled to allow for post expansion of the foam.

Fill to approximately 80% of joint depth for optimum results.

On horizontal surfaces always work away from the exuding bead and work upwards on all vertical surfaces.

When filling deep joints apply in layers, waiting until each layer has skinned and partially cured before applying the
next.

Applying a light misting of clean water between each layer before subsequent application will assist adhesion and
cure speed.

Ensure any substrate requiring cleaning is solvent resistant before proceeding.

Cured foam can only be removed mechanically. Excess material may be trimmed off using a sharp knife or sanded down.

Please Note
This foam is not UV resistant and should be protected from sunlight with a suitable opaque sealant, filler or paint.
