SUPERLATEX

Polymeric Additive for Mortar and Concrete

Description

SUPERLATEX is a formulation consisting an aqueous emulsion of a flexible copolymer, emulsifiers, stabilizers and additives. SUPERLATEX, once added to a sand/cement mortar, greatly increases its anchoring capability, flexibility and waterproofness.

Usage field

As a binder for:

  • concrete slabs to be anchored to the bottom;
  • cold shuts;
  • new plaster on old walls;
  • new plaster on concrete surfaces;
  • installation of covers and thresholds made ​​of marble, granite, etc..

As a substantial modifier of Portland cement mortars to make:

  • repair mortar for maintenance patching;
  • mortar for the restoration of deteriorated concrete;
  • thin mortar for highly adhering skim coating;
  • plasters with very low water absorption rate;
  • coves at corners to allow subsequent waterproofing treatments

As an additive on osmotic concrete to reduce its drying speed and increase its flexibility.

Packaging

NORDLATEX is available in 1 - 5 and 25 liters containers.

Application

Taking into consideration that, to achieve good results, film formation should be carefully avoided, working with SUPERLATEX must be carried out "wet on wet".

SUPERLATEX is applied in different ways depending on the type of intervention required, e.g.:

Adhesive for anchoring screeds and cold shuts

  • soak until fully saturated;
  • apply a first coat of SUPERLATEX diluted with two parts water;
  • add to the SUPERLATEX and water solution, prepared according to the previously explained procedure, cement and water until a grout is obtained for scratch rendering the surface.;
  • apply the grout with a flat brush or a scrubbing brush to the area to be treated a few minutes before casting.

Plaster adhesive

  • make the surface wet;
  • apply a first coat of SUPERLATEX diluted with three parts water;
  • add to the solution of SUPERLATEX and water (prepared as mentioned above) sand and cement to obtain a grout for the surface scratch coat.

Installation of covers and marble thresholds

  • soak the surface;
  • apply a first coat of SUPERLATEX diluted with one part water;
  • add to the solution of SUPERLATEX and water (prepared as mentioned above) sand and cement to achieve a mixture suitable for making the mortar bed for the chosen material.

Repair mortar for maintenance patching, mortar for repairs of deteriorated concrete and thin mortar for highly adhering skm coating

  • soak until fully saturated;
  • apply a coat of SUPERLATEX diluted with three parts water;
  • prepare a mortar with sand and cement using, instead of water, the solution of diluted SUPERLATEX, you previously used as a primer.

Renders with very low water absorption

  • soak the surface;
  • apply a first coat of SUPERLATEX diluted with two parts water;
  • add to the solution of SUPERLATEX and water (prepared as mentioned above) one part cement and three parts sand.

At angles coves for subsequent waterproofing treatments

  • soak the surface with a coat of SUPERLATEX diluted with three parts water;
  • prepare a mortar with one part cement and three parts sand by using, instead of water, the solution of SUPERLATEX and water, prepared as above mentioned. The same mixture can be used to cover any cut tie rods on concrete walls before waterproofing.

Warning and informations
  • Do not use lime in the mix.
  • There are certain rare types of "salted" sands with high salt content that may not be compatible with SUPERLATEX.
  • Do not apply at temperatures close to 0°C.
  • Avoid direct contact with copper and manganese.
  • Shake the packaging before use.
Preservation

Store in a covered place at room temperature between +4 and +30°C. Stable for over two years.
