ACS Dry Rot Paint is a specially formulated preservative emulsion coating for control of fungal growth and infection such as Dry rot (Serpula lacrymans) on brickwork, masonry, render and timber. This paint is not a treatment for the eradication of Dry Rot but can be used to protect timbers in proximity to a fungal outbreak or those used in reinstatement after an outbreak. It is a particularly useful treatment for coating the backs of joinery (skirtings/architraves) and concealed parts of window and door framework.

ACS Dry Rot Paint is a high quality water based coating containing just over 1.0% w/w 3-Iodo-2-Propynyl-N-Butyl Carbamate. It has been designed as a highly visible surface biocide and as a sterilising treatment against Dry rot and other decay fungi.


The main uses of ACS Dry Rot Paint are readily identified as:-


1. A surface biocide and preventative treatment against decay fungi on mineral and timber substrates.

2. A fungicidal coating for joist ends, apertures of windows and doors an exposed brickwork between floors.

3. A biocidal barrier under plaster and render.

4. A toxic barrier on the backs of joinery and concealed linings of door and window frames.
