1 × ≥ 350 g/m² Pyroplast Wood P

1 x 120 g/m² Sika Pyroplast Top WB (optional)

Consumption rates are based on fire performance according EN 13501-1

B EN 13823 FIGRA ≤ 120 W/s und LFS < edge of specimen and
THR600s ≤ 7,5 MJ
and
EN ISO 11925-2 Exposure = 30 s Fs < 150 mm within 60 s

d0 No flaming droplets/ particles in EN 13823 within 600 s

(As entire coating system. If no Topcoat is applied, classification Bs2d0 is met!)

If consumption rates for alternative standards are requested, please consult the Technical Department at 0113 2455450.

Relative air humidity

Max. 80 %, application temperature shall be at least ≥ 3 K above dew point.

During application and drying of the total Pyroplast Wood coating system including Pyroplast Top WB, as well as transportation, special protection measures must be taken against weathering.

Substrate temperature

Object temperature not below + 10°C, to max. + 40°C*

* If higher temperatures occur, please consult the Technical department for further assistance.

Substrate moisture content At high moisture content of the timber (> 15%), the coating is unlikely to dry satisfactorily and blooming may result. Therefore the moisture content of the timber should be, as near as possible to the level it will stabilise at in
use.
Waiting time to overcoating

Pyroplast Wood P requires a minimum of 24 h drying prior to application with itself.

Overcoatable with topcoat Pyroplast Top WB after approx. 48 hours.

A complete drying of the fire protection coating prior topcoat application is highly recommended. Through-drying of Pyroplast Wood P can be checked by a ‘finger-nail test’. Prior to further applications possible contaminations must be removed.

Drying time

At approx. + 20°C temperature and 60 % relative humidity:

Touch dry after ~6 h

Overcoating after ~24 h with itself

Overcoating after ~48 h with Pyroplast Top WB

Different temperatures, different relative humidity and different fire protection coating thickness 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


Pre-Treatment:

Substrate must be dry, free from dust, oil, wax, grease, dirt, resin, etc.; Existing coatings with poor adhesion have to be completely removed, e.g. with solvent-based paint stripper or to be sanded down. Surfaces that have been treated with non-acid resistant coatings or release agents such as emulsion paints containing lime, chalk or lithopone should be sanded down completely.

Timber substrates with wetting difficulties should be roughened thoroughly with abrasive paper. The moisture content of the timber should be below 15 %.

If resistance to wet rot, fungi or insect attack is requested, the manufacturer recommends using commercial preservative agents based on oil-alkyd resins provided they are compatible with the Pyroplast fire protection system.

Apply Pyroplast fire protection coating system only after the preservative treatment is completely dry. The moisture content of the timber should be below 15 %. Sika Pyroplast Wood P Primer may be used to allow sufficient adhesion or avoid diffusion of wood ingredients on resinous wood.

Mixing:

Stir thoroughly prior to application, ensuring the product is 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 that the selected ap- plication method will provide the requested results.

Brushing & Rolling:

  • Material shall be applied in supply viscosity
  • Load natural fine bristle brushes or short pile lambswool rollers are recommended
  • Application of two coats of Pyroplast Wood P to a load of 175g/m² each coat is recommended

Airless Spraying:

  • Material shall be applied undiluted
  • Airless spray equipment with pressure ratio ≥ 30 : 1
  • Filters should be removed
  • Hose diameter not below ⅜ "
  • Whip line 1.5 - 2 m, NW 6, may be used
  • Recommended nozzle sizes:
    • Pyroplast Wood P Primer: 0.27 - 0.34 mm (0.011 - 0.017 inch)
    • Pyroplast Wood P: 0.34 - 0.64 mm (0.017 - 0.025 inch)
    • Pyroplast Top WB: 0.27 - 0.56 mm (0.011 - 0.023 inch)
  • Hoses must be used for water-based products only

Above data shall be used as a guideline with variations being made to suit local conditions. Immediately clean equipment after use with water.
