“Emex” Waterproof Polyurethane Membrane: Preparation

     The application of the Waterproof Polyurethane Membrane requires preliminary preparation.

     The instructions contained by these pages have only informative purpose. For detailed instructions please read the Data Sheet of the product or ask for special instructions.

     We do not recommend applying by people who have not experience in this area.

     The surface preparation is the main factor in obtaining maximum adherence which ensures the exploitation durability and coating preservation. Therefore:

  1. The product is to be adjusted to the application temperature 24 hrs before the application.
  2. Before opening the cover remove the dust or any other residual materials.
  3. The product is to be mixed in its original packing, using a mechanical mixer in order to disperse any potential deposits.
  4. Filter the product before use.
  5. The density will be established according to the type of application by adding “Emex” Polyurethane Thinner, or any other thinner recommended by the manufacturer (Ex: “Emex” Epoxy Thinner).
  6. The A ingredient is well mixed inside the package using a mechanic mixer then the B ingredient is added according to the Data Sheet reports of the product.

Application conditions:

  1. The optimum application temperature for the product: 15 - 30°C.
  2. Approximate environment moisture max. 65%.
  3. The support temperature will be at least 3°C above the dew point to avoid the moisture condensation on the support, which could decrease the adherence, or could cause blisters.
  4. The products are not to be applied in bad conditions such as fog, rain, snow, wind, in the presence of dust or when the support is covered by water or ice.
  5. The product’s application under 15°C can be done only after notifying the manufacturer, using special materials for this purpose.

     It is mandatory to check the Data Sheet of the products to obtain optimum results.

Waterproof Membrane: Surface preparation for application

     The Waterproof Membrane application on the concrete, mosaic surfaces or any kind of concrete materials used for designing floors will be done only after the necessary preparation of the support, because this stage has a decisive influence upon the quality and durability of the coating. Therefore:

  1. Concretes or new caps (inclusively reparations) require minimum 28 days for hardening and drying before the application (except the auto-leveling caps with rapid dry); if these conditions are not met the product’s resistance will be damaged and will cause exfoliation and blisters.
  2. The cement support has to be intact, without any traces of contaminants such as oil, grease, surface treatments or coatings, etc.
  3. Higher spots on the surface will be removed through polishing and the free particles will be removed mechanically. The existent coatings have to be checked, mechanically cleaned in order to obtain an adequate support with an appropriate adherence.
  4. Before applying the product repair the empty spots or other imperfections, preferably with epoxy lute (Epoxy Plaster “Emex”).
  5. In the case of previous coatings, these will be removed no matter their state (except epoxy paints or epoxy floor varnish in good condition, which will be polished).
  6. Previous epoxy or polyurethane protection coatings, both paints and floors, in good condition, which maintain their polish, will be roughed with the polishing disc tool or abrasive strips.
  7. In order to remove existent particles (others than epoxy) use the “Emex CM Cleaner” Varnish Remover Solution or the “Emex PC Eco” Ecological Varnish Remover.
  8. Old layers can be removed by polishing with mechanical brushes or by burning.
  9. The surfaces to be covered with Polyurethane Membrane will be cleaned and degreased, roughed and the resulting dust will be removed with soft brushes or by blowing with compressed air.
  10. The surfaces have to be smooth, pain and dry to 4% moisture.
  11. Before applying the floor, apply “Emex” Primer Polyurethane Base Coat or the “Emex” Primer Epoxy Base Coat.

     Metallic inclusions will be cleaned using “Emex Rust Stop” Rust Removal Solution and necessarily covered by “Emex” Anticorrosive Polyurethane Base Coat or “Emex” Anticorrosive Epoxy Base Coat.

Waterproof Polyurethane Membrane: Application

     The product will be applied on the support surface only after its preparation according to the instructions in the previous tab, or according to the Data Sheet based on the type and condition of the support.

     The Waterproof Polyurethane Membrane application will be done by casting and dispersing with combs or special pullers, which have the option of setting the teeth level, therefore:

  1. The product is prepared according to the instructions.
  2. The surface is prepared according to the instructions.
  3. Before casting the floor apply “Emex” Primer Polyurethane Base Coat or “Emex” Primer Epoxy Base Coat.
  4. After is has dried (6-12 hours) prepare the Polyurethane Membrane according to the preparation instructions from the previous tab or to the Data Sheet.
  5. Very important elements:
    1. the mixing report is gravimetric NOT volumetric.
    2. mix only the quantity to use only during its feasibility time of the mix (pot-life), approx. 30 min. at 230C.
    3. The pot-life can drop when the temperature rises and the quantity of mixture increases due to the chemical reaction acceleration, at temperatures higher than 23°C.
    4. The product and the hardener agent will mix for max. 3 minutes at low rotation speed.
  6. The Polyurethane Membrane will be cast and dispersed with the puller. The final level is given by leveling the puller’s teeth.
  7. After dispersing, the air from the casted layer will be removed by using pin roles. To step on the fresh floor use only special nail shoes.
  8. “EMEX” Waterproof Polyurethane Membrane has a drying period of approx. 8 hours at 20 - 23°C, period of time which also enables the swelling. If kept at temperatures under 5°C the hardening will be irreversibly damaged.
  9. The endurance parameters, both chemical and mechanical will be done aprox.4 days after application, at a temperature of 20 – 23°C.

Restrictii de aplicare      NOTE: The Waterproof Polyurethane Membrane in contact with water during the preparation stage/ the application will suffer irreversible damage and the resulting quality will be significantly affected.
