MB FL 2K

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 and pore-free substrates.

Absorbent mineral substrates, not self-compacting concrete (SCC), may be slightly damp.

Remove projecting seams and mortar remains.

Break off or chamfer corners and edges.

Prime absorbent mineral substrates with Kiesol MB.

Create a scratch coat using the product as a contact layer and in order to prevent blisters.

If necessary, use suitable products to level out any sloping (e.g. Betofix R4 EM).

Waterproofing:

Reinforce connection areas such as floor-to-ceiling doors and window elements, internal corners, floor-to-wall connections and transitions to balcony edge profiles with joint tape from the Tape VF series.

In interior areas:

Interiors: calcium sulfate screeds must be sanded then vacuumed.

Residual moisture CA/CAF screed heated < 0.3 CM-%/ unheated <0.5 CM-%.

Prime gypsum-based substrates (Primer Hydro F).

Waterproofing:

Apply at least two coats of the product to the prepared substrate in accordance with the regulations.

The total dry layer thickness must be ≥ 2 mm.

Connection details/building element joints

Reinforce internal corners and connection joints, as well as connections to non-mineral building components with joint tape from the Tape VF series.

Apply the product, embed Tape VF over the entire surface, ensuring that there are no bubbles or creases.

Laying the tiles:

Existing waterproofing layers must be completely dry before further work is carried out.

Apply the product as a thin-bed mortar using a suitable notched trowel, and lay the covering material in the fresh mortar bed before a skin forms.

In outdoor areas or when laying large-format tiles and slabs, application using the buttering floating method is recommended.

Immediately remove any soiling / mortar residue on the surface of the covering with water, keep the joint area free of mortar residue.

Grouting tiles:

The joints must be completely dry to avoid trapping moisture in the joint. Apply MB FL 2K grout to the joints with an epoxy grouting scraper in sections. If necessary, the consistency for use as a grout can be adjusted by adding max. 300 ml clean water (to 6.67 kg material). Wipe surfaces promptly with a sponge and wash clean with a sponge float and water. After complete drying, residues/adhesions can be cleaned with Remmers Clean FL.

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).

Clean tools with water while the material is still fresh.

Any material that has already begun to dry can only be removed mechanically.

Dry, adhering material can be cleaned with Remmers Clean FL.

If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 9 months.
