Sika Pyroplast Wood P forms a carbon char when affected by heat as it uses a water based fire protection coating intended for internal use.
Coverage = 2.86m2 per 1kg
Sika Pyroplast Wood P slows the inflammation of natural wood by-products and is comprehensively worked on to ensure protection against flames spreading.
Sika Pyroplast Wood P contributes a beautiful option to architects, builders and end-users, all while accentuating the interior composition of timber arrangements.
Lessens the combustibility of hard- and softwood > 10 mm thickness and other timber by-products, such as plywood, chipboard, fibre insulation board, hardboard and also on veneering > 12 mm thickness.
Shields against heat, checks fire, restricts the generation of fire and spread of flame and reduces flue-gas temperatures.
Sika Pyroplast Wood P should not be used in areas of high humidity, heat sources or on surfaces where significant physical impact is likely.

Intumescent coating, Sika Pyroplast Wood P
Topcoat, Sika Pyroplast Top W
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 rubbed 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 rubbed down completely. Timber substrates with wetting difficulties should be roughened thoroughly with abrasive paper.
Pre-Treatment with Wood Preservatives:
If resistance to wet rot, fungi or insect attack is requested, we recommend using commercial preservative agents based on oil alkyd resins provided they are compatible with the Sika Pyroplast fire protection system. Apply Sika 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.

Preparation of Material:
Stir thoroughly, free of lumps.
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 an 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 application method will provide the requested results.
- Material shall be applied undiluted
- Airless spray equipment with pressure ratio ≥ 30:1
- Filters should be removed
- Hose diameter not below 3/8 “
- Whipline 1.5 – 2 m, NW 6, may be used
- Recommended nozzle size for Sika Pyroplast Wood P Primer: 0.27 – 0.34 mm or 0.011 – 0.017 “

Sika Pyroplast Wood P Primer, Sika Pyroplast Wood P and
Sika Pyroplast Top W: Object temperature not below + 10° C, to max. +40° C*
Relative humidity max. 80%
Application temperature shall be at least > 3 K above dew point.
In case relative humidity exceeds 80% special measures must be taken to prevent the condensation forming while application.
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.
*If higher temperatures occur, please consult the Technical department for further assistance.
At approx. + 20° C temperature and 60% relative humidity.
Sika Pyroplast Wood P Primer:
