Application Methods

GROUTPAINT® is a water-based acoustic anti-vibration adhesive paint. Different from the conventional damping materials, GROUTPAINT is a low-density product, which has a high damping performance on the premise of its low weight. The product is a key choice to reduce air noise and reverberation time, ideal for use on large surfaces for environments with strict additional weight requirements, such as plasterboard and concrete surfaces, constructions structures and building ceilings, yachts, vehicles and trains, etc. It provides a quick drying performance, environmentprotection, performance and fire resistance. GROUTPAINT is a 95% recycled compound. This product can be applied on almost all surfaces by spraying, either using a pressure tank spray machine or an endless screw spray machine system gun.

GROUTPAINT® should be diluted with water (10%). It is advisable to apply a thin coat of ® (800g/ sq.m) as a primer to enhance adherence and to let it dry out completely before the next coat is sprayed. After that, you can apply more 2 or 3 coats, reaching 15mm maximum thickness. The product effectively reduces the reverberation time, the resonance effect and the transmission loss is increased. Obviously it controls the resonant frequency of the raw base material, caused by micro vibrations, improving the noise reduction rate.


10Kg bucket, Water-based, easy to use and clean, 95% recycled compound.
Main composition: Cellulose, textile, Rockwool fibres and inert mineral fillers.
Fire Class: A2-s1,d0, Non-Flammable (similar to old M0, French Norms CSTB). .
Absorption coefficient: 0,41/m² 12 to 15mm thickness
Application: any pressure tank spray machine or an endless screw spray machine using a large nozzle, from 8 to 12 mm.
GROUTPAINT should be diluted with water (10%). It is important to keep the same dilution during the whole job in order to ensure a continuous final look. DO NOT FORGET to add the small bottle of additive before application with an electrical mixer. This additive increases air entrainment and facilitates spraying application.


GROUTPAINT is fully compatible with all concentrated aqueous Paints used as colorants. Add the dye in the mix with an electrical mixer and make the color test before applying.
Drying: 24 to 36 hours (allow enough ventilation)
Coverage: 4kg/m² = 5mm to 12 Kg/m² = depending on required sound absorption.
