ColourPicker Explained

In general we sort colours for products into 2 main groups - ‘Ready Mixed’ and ‘Tinted’.
Tinted colours will always be more expensive than Ready Mixed colours as they need to be produced at the time of order using a tinting machine dispensing colourant into a base*.
During busy periods, this means that tinted colours could take longer, for example – a ready mixed colour ordered on a 3-5 day delivery might arrive within 3 days, however a tinted colour might take the full 5 days to arrive.

To find Ready Mixed colours, search "ready mixed" or select the Ready Mixed 'colour chart'. To see Tinted colours select a colour chart such as RAL, BS, NCS, etc. or search for a colour/hue to see available or related options.

To ensure fair pricing, we split colours into ‘Price Bands’ to group together similar priced colours. If you wish to search for the cheapest tinted colours, always select Price Band 1.

We make every effort to list all available colours, however we also offer a colour match service which can be accessed by contacting our Technical Team on 0113 245 5450 (option 2) or emailing [email protected]

*Colours are sold in the nearest tin size but actual paint volume per tin may vary up to 10% depending on colour

Colour reproduction of the Products on the Site is limited by the technology used to deliver web pages and by the colour representation of Customer’s own monitor and computer set-up. We have made every effort to display as accurately as possible the colours of our Products but we cannot guarantee that the colour shown on Customer’s monitor’s display will accurately reflect the colour of the Product on delivery. We recommend that Customer first purchases the smallest Product available or access an industry standard colour chart in person (and not digitally) to ensure that the colour is acceptable for its purposes.

Application Information

Consumption	1 × 120 g/m² Pyroplast Wood P Primer (depending on wood surface) 1 × ≥ 350 g/m² Pyroplast Wood P 1 x 120 g/m² 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 s1 SMOGRA ≤ 30 m2 / s2 and TSP600s ≤ 50 m2 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 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 on 0113 2455450 (option 2) or send a message to [email protected] where we will be happy to discuss your project.
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 ‘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 %. 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 of Pyroplast Wood P 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 Sika 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.
