Acoustic Plaster Colours

BASWA Colour Chart

BASWA Finishes can be integrally tinted to match any design intent by adding BASWA Colours Tint Additives. Given the porous properties of BASWA Finishes, each colour recipe is visually compared with the original colour swatch by the BASWA Techinical Department. One vial of tint additive, supplied by BASWA acoustic, is added to each pail of finish coat material and pails are batched to ensure a consistent finished colour.

What Acoustic Plasters Will Do for You:

Our acoustic plasters quieten your space by absorbing noise. This sound-absorbing plaster draws in and envelops loud and harsh sounds, giving you the silence you need to concentrate, relax, or hear your own music clearly. If you’re plagued by the sounds of traffic from outside, muffled conversations among your upstairs neighbours, or other distracting sounds, our acoustic plasters can finally give you some much-needed peace and quiet. From internal wall soundproofing for your flat's bedroom to soundproofing ceilings and exterior walls to cut down on the distraction of noisy neighbours, our acoustic plaster is perfect for a variety of applications.

Acoustic plasters will add privacy to your space by preventing sound from escaping. With our acoustic plaster noise insulation for walls and ceilings in place, those outside will not be able to hear what is happening inside. You are free to have conversations without fear of being overheard, play loud music without worrying about complaints from neighbours, or otherwise go about your business without worrying that the noise you are making will invite unwanted intrusions to your privacy.
