The Wykamol Eco System
To prevent further rain penetration through the exterior wall, pointing should be made good and an application of DrySeal Masonry Protection Cream is essential. With up to 29% energy savings, not only does DrySeal prevent any further dampness coming through the outer leaf of the cavity, but it could save the homeowner almost the same amount of money on their energy bills as promised by CWI companies (up to 33%). This product allows the walls to continue to breath, encouraging the CWI to dry out while preventing any further water ingress.
Interior plaster finishes must be removed, as they will have been contaminated and dampened by the bridging of the cavity. The walls will need to be dried out and an application of Wykamol’s Renovation Plaster applied, which effectively controls the migration of damp and harmful salts. It also has insulating properties which will help improve the energy efficiency lost by the failed CWI.
For particularly saturated masonry however, we may recommend an application of DampStop Mesh Membrane, which can be applied directly on to wet walls, saving time and money.
After finishes have been applied, the system is completed with an application of ThermalDry Anti-Condensation coating, a unique product in the market which utilises micro-technology to prevent condensation and black spot mould from forming on any remaining cold spots on the walls. Where CWI has been poorly installed, gaps can be left uninsulated, causing spots on the interior walls to become significantly colder than the surrounding area, and condensation will occur as a result of this. Walls treated with ThermalDry avoid condensation for up to 60% longer.
