DESCRIPTION: Water based fire retardant

APPLICATION: Fire retardant system for timber substrates that require euroclass B and euroclass C spread of flame fire protection.

FEATURES: Without colour or odour. Fire retardant properties will remain active for the lifetime of the substrate. Ecologically friendly. Non-toxic. For internal and external use, cannot be washed out of the substrate once applied. Not broken down by water or humidity. Does not leach. Final finish can be left natural or over-coated with certain stains, varnish and paint. (Contact us for details of coatings that would be suitable) A triak coating is always recommend.

This product is classified Xi - Irritation: Irritates eyes and skin.

DIRECTIONS FOR USE

Substrate: The substrate must be clean, dry and free from contamination; existing coatings must be removed by stripping or sanding.
Wood moisture content should be 20% or less.
It is recommended that a sample of the substrate is coated to establish both absorbtion properties and possible colour change.

Application: Approx 3 coats depending on applicator, coats should be applied at intervals of minimum 1 hour giving a total coverage of minimum 270 m/l m2.
Do not mix with other solutions, stir well.
Use brush, roller, spray (use appropriate mask when spraying), dip, or vacuum method.
Minimum temperature for application 5 degrees C do not apply to frozen substrate.
Coverage will depend on a number of factors, including timber species, surface condition,moisture content, method of application and climatic conditions during application.

Drying Times: Drying time 24 hours at + 20C/65 relative humidity. Maximum fire retarding capabilities will be achieved after 7 days.
Note: Drying times are dependent upon absorption of substrate and drying conditions. At low temperatures and/or conditions of high relative humidity, drying times will be extended.

Storage and Transportation: Supplied in sealed containers and should be stored at temperatures above zero. The warranty period of storage is 36 months.

Protection Period: Fire retardant properties tested to NT 053 & NT 054 on a 20 year accelerated Weathering Cycle.

Disposal: It can be safely disposed of as a household product.

SPECIFICATION: Hr-Prof is a patented product. Pack sizes: 1L, 5L, 20L and polymeric tanks of 200L and 1,000 litres.

Final finish: Natural or over-coated with certain varnishes, stains and paints
