During application and drying of total Sherwin Williams Firetex Concrete WB-120 coating system
including Sika Unitherm topcoats special protection measures must be
taken against weathering.

Furthermore, proper ventilation is recommended.

Surface temperature

Object temperature not below + 5°C, to max. + 40°C.

If higher temperatures occur, please consult our technical department for further assistance.

Waiting time to overcoating

Prior to further applications possible contaminations must be removed.
Sherwin Williams Firetex Concrete WB-120 requires a minimum of 12h drying prior
to application with itself.

Sherwin Williams Firetex Concrete WB-120 requires a minimum of 24h drying prior to application of overcoating.

Drying time

Approx. 24 h after application of last coat at + 20°C object temperature and 60 % relative humidity.

Different temperatures, different relative humidity and different coating
thicknesses have an influence on drying time.



Ecology, Health & Safety


User must read the most recent corresponding Safety Data Sheets (SDS) before using any products. The SDS provides information and advice on the safe handling, storage and disposal of chemical products and contains physical, ecological, toxicological and other safety-related data.





Application Instructions


Substrate Preparation:

Surfaces to be coated must be brushed off and vacuum cleaned afterwards. They have to be solid to support any loads, free of sludge, dirt, oil, grease, wax, water-repellent agents and other contamination. Residual humidity in the concrete must be below 4 % according to CM-humidity measuring instrument.

In case of existing coatings, a compatibility test with the fire protection system is mandatory.

Any damage or imperfection (impact, corrosion, etc.) should be repaired prior the coating with the adequate repair mortar.

Mixing:

Stir thoroughly with slowly turning mechanical stirrer, free of lumps.

Application:

The method of application has a major effect on achieving uniform thickness and appearance. Spray application will give the best results. The indicated dry film thickness is easily achieved by airless spray. In case of application by roller or brush, additional layers may become necessary to achieve the required coating thickness, depending on type of construction, site conditions, colour shade etc. Prior to application a trial on site may be useful to ensure the selected application method will provide the requested results.

Airless spraying:

  • Material shall be applied undiluted
  • Airless spray equipment with transmission ratio > 45 : 1
  • Screens and filters must be removed
  • Hose diameter not below ⅜ “
  • Whip 1.5 - 2 m, diameter 6 may be used
  • Nozzle size 0.46 - 0.61 mm (0.019 - 0.024 inch)
  • Hoses must be used for water-based products only

Brushing / rolling:

  • Material shall be applied undiluted
  • Load natural fine bristle brushes or short pile lambswool rollers are recommended
