We requested samples to be sent back to the UK so that Wykamol's laboratory technicians could undertake testing for water content and salt determination.
After rigorous testing and analysis at our Head Office in Burnley, Lancashire, we proposed that all the plaster be removed and that a coat of HydraDRY applied.
HydraDRY is a BBA and WRAS Approved, cementitious compound designed for application to the internal surfaces of walls and associated solid floors, which could be subject to penetrating dampness.
Next, we advised the addition of Renovation plaster to a depth of 5-7 mm, followed by a finishing plaster.
Finally, a layer of ThermalDRY, an Anti-Condensation Coating which is both thermally insulating and water repelling. It increases the wall temperature, therefore preventing the formation of condensation and mould growth.
Furthermore, some walls had been re-pointed with a very hard mortar, and we suggested using a lime-based grout to replace the hard grout to allow the wall to breathe.
