Installation Guide
A step-by-step guide to treating rising damp with StopDamp+ — from removing contaminated plaster through to a dry, paint-ready wall.
Everything needed to carry out a complete StopDamp+ installation, from injection through to replastering.
Follow each stage in order. Skipping ahead — drilling before checking for services, or replastering before the injection line has been treated — compromises the whole system.
Remove all loose, damaged and salt-contaminated plaster from the affected area, exposing the masonry sufficiently to carry out the treatment.
Identify the appropriate horizontal mortar course for the treatment. Before drilling, check for concealed electrical cables, water pipes and other services.
Measure and mark the drilling points 100 mm apart along the selected mortar course, using a level or straight edge to maintain a consistent horizontal line.
Using a 12 mm drill bit, drill the holes at the marked points — into the mortar course, not through the sandcrete blocks.
Thoroughly remove drilling dust and loose debris using the dust/debris removal tool. Debris left in the hole can prevent adequate penetration of the cream.
Readiness check: every hole should be clear, clean and ready to receive StopDamp+ Injection Cream.Using a caulking gun or applicator gun, inject StopDamp+ Injection Cream into each prepared hole, working systematically along the mortar course so that every hole is treated.
Apply StopDamp+ Baseshield below the injection line and down to the floor, ensuring continuous coverage across the required area.
Mix 1 bag of StopDamp+ Cement Mix with 1 bag (50 kg) of Portland cement. StopDamp+ Cement Mix is an antisalt additive for replastering — combine with plastering sand and water as specified, and use the resulting mix to replaster the treated wall.
Allow the treated and replastered wall to dry thoroughly. Do not paint while the wall is still damp — confirm the surface is dry before proceeding.
Once the wall is sufficiently dry, paint the replastered surface to complete the treatment.
Treat the moisture pathway. Restore the wall.
