GUM GUM SPRAY bag version

RESILIENT SOUND-IMPEDANCE LAYER WITH PREMIXED RUBBER GRANULES

GUM GUM SPRAY is a resilient impact sound layer made directly on site from pre-mixed SBR rubber granules and selected binders (Part A, 24 kg bags), mixed with a liquid additive (Part B, 4 L packs) and water.

Sprayed with the GUM GUM MACHINE (or spread by hand), it follows every shape and covers pipes and services without a levelling layer: ideal for low-thickness floating screeds in renovations, and for stairs, wall cavities and acoustic bridges that a roll cannot reach. 89% recycled material.
