The flat was poorly done up, laminate bosrd of stopped short of skirting board.. I'd already got the rockwool sound panels against the wall to dampen noise from below. I went around all the skirting boards to seal all gaps. The rockwool sound panels absorbed way more sound as can be expected. However doing this led to a 15%sound reduction. This may not sound very significant but it reduced the reverberation of their voices and noise and so softened some of the noise to a muffle. Review: Sealent - Nice sealant, dries cream not white, dries quick and smooth ready to paint ## Features - Contains sensitizing substances.

V easy to apply and very effective acoustically. Really notice a difference. Unfortunately the tube itself split and leaked the sealant into the applicator - will order another tube in hope this was just a one-off! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reduced some noise from flat below, needs rockwool panels for proper effect *by E***N on 11 June 2023* I bought this when I lived in a flat with noisy neighbours.
