Preparation
-
Substrate requirements
The substrate must be clean, dry, flat and capable of bearing a load, and free of dust, oil, grease and release agents.
Roughen non-mineral substrates.
-
Preparations
Remove projecting seams and mortar remains.
Break off or chamfer corners and edges.
In coves, embed Tape VF series into the material and smooth to < 20 mm.
Alternatively, use a suitable mortar to produce a sealing cove.
Close indentations > 5 mm with a suitable filler or with MB 2K mixed with suitable quartz sand (MR of between 1:1 and 1:3).
Roughen the surface of plastic pipes with sandpaper; clean and, if necessary, sand metal pipes.
If necessary, provide damp proofing.
Prime absorbent mineral substrates with Kiesol MB.
Apply a scratch coat (approx. 500 g of MB 2K/m²) with the product itself as a contact layer and in order to prevent blisters.
-
-
Preparation
-
Combination container
Mix the liquid component (component A) with a suitable mixing tool.
Pour the loosened powder component (component B) completely onto the liquid component.
Mix for approx. 1 minute before suspending the mixing process to allow the air that has been stirred in to escape.
Remove the powder adhering to the side.
Mix again for approx. 2 minutes.
Keep the mixing tool near the bottom of the bucket while mixing.
-
Application
-
Application requirements
Temperature of the material, air and substrate: from min. +5 °C to max. +30 °C.
-
Vertical surface waterproofing
Apply the product in two layers on the previously prepared substrate.
Horizontal surface waterproofing
Apply the product in two layers on the previously prepared substrate.
After the waterproofing has dried thoroughly, place two layers of PE sheet over the waterproofing before the screed is laid.
At the edges, the waterproofing layer is applied up to the upper edge of the floor or up to the horizontal barrier.
Horizontal waterproofing in and underneath walls
Apply the product in two layers on the previously prepared substrate.
Connection details/building element joints
Use the joint tape system to bridge corner and connecting joints, as well as connections to rising components (e.g. full-length windows, doors).
Apply the product, apply Tape VF over the entire surface and embed so that it is crease-free.
Pipes passing through walls
W1-E: seal passing-through pipes by using the product to form a cove around them.
W2.1-E: use a suitable loose/fixed flange to integrate pipe lead-throughs in the waterproofing material. Alternative: use Remmers pipe flange.
Use Remmers Pipe Flange in cases where the water load is "pressing water".
Plinth render
If render is to be subsequently applied, an additional layer of grout should be spread on to the last layer of waterproofing. SP Prep can then be thrown over the entire surface of the fresh layer of grout.
Work can be continued with compound mortar and reinforcement mortar after approx. 4 hours without an additional layer of grout/preparatory mortar.
Follow-up work and coverings
After 4 hours, work can be continued with adhesive mortar, filling
mortar or reinforcement mortar.Coating
Direct coating with binder-rich dispersion coats.
Always set up a trial area/trial areas first.
-
Application instructions
-
In the case of liquid-applied waterproofing materials, direct sunlight and/or wind exposure can cause accelerated skin formation and accompanying blistering.
Do not use in direct sunlight.
Do not use on untreated aluminium.
The scratch layer does not as a rule count as a waterproofing layer.
The maximum total wet coat thickness must not exceed 5 mm.
Moving the material (e.g. by stirring) in the mixing bucket can prevent premature skin formation.
Mortar that has already set cannot be made workable again by adding
water or fresh mortar.Protect the fresh waterproofing layer from rain, direct sunlight, frost and condensation water.
Once dry, protect from mechanical damage.
Add a further load-distributing layer if using the product for waterproofing under raised floor supports.
Ensure sufficient ventilation when applying the product in closed areas (wear respiratory protection if necessary).
Please contact Remmers Technical Service (phone +49 5432 83900) before applying with machine processing.
