POLYMER CEMENT COATING
Treating a damp wall
Treating a damp wall
Injecting or treating a damp wall is usually a very time-consuming job. Sometimes you have to wait months before you can finish the wall completely.
With WP7-501 Basement + Wall Waterproof you can do this considerably faster. It immediately forms a moisture-resistant barrier, which allows you to plaster or paint over the wall immediately after curing.
STEP 1: PREPARATION
Mark the zone to be treated. Do this up to 25 cm above the damp zone.
Remove all the plaster with a hammer and chisel or with a rotary hammer.
Remove dust.
STEP 2: PREPARING AND APPLYING PRIMER
Prepare the primer in a ratio of 1:1 with water.
Bring both together in the supplied spray bottle.
Apply the primer generously on the wall to be treated, also moisten the corners.
STEP 3: PREPARING COATING
Measure the correct amount of water and pour it into the mixing bucket.
Now add the polymer cement in steps and mix it thoroughly with a cement/paint mixer.
Repeat this until you have processed the correct amount and you obtain a homogenous mass.
Respect a rest period of 2 minutes, then mix again.
STEP 4: APPLYING THE COATING
Apply the first layer of WP7-501 Basement + Wall Waterproof of +/- 1mm on the wet primer, using a stiff brush.
The humidity during application and curing should be between 50% and 80%.
After application of the first layer, allow 2 to 5 hours for curing.
The first layer must feel cured before you can apply the second layer.
Apply the second layer in the opposite direction of the first layer.
After curing of WP7-501 Basement + Wall Waterproof you can immediately proceed to the finishing. Make sure there is good air circulation to speed up the curing process.
Always consult the technical data sheet for the full instructions.
