site conditions
pyroplast-HW100 is suitable for internal, weather tight environments only. The product must only be applied in temperatures above 10°C and a maximum relative humidity of 70%. Low temperatures and/or high humidity will cause prolonged drying times and may lead to surface defects.

surface preparation
pyroplast-HW100 is suitable for application to internal timber surfaces. It is not suitable for application to artificial timber or pre-finished timber surfaces. All timber surfaces to be treated must be free from surface moisture and any contamination such as dust,
grease, wax, and resin. Oily or resinous timbers should be washed with methylated spirits and allowed to dry thoroughly.
Existing coatings must be completely removed by stripping or sanding. pyroplast-HW100 is not suitable for application to surfaces which are likely to be subject to high levels of abrasion e.g. doors, stair treads and risers, and hand rails.
The moisture content of the timber must be no more than 15%. pyroplast-HW100 is not suitable for high humidity or wet environments i.e. kitchens, bathrooms and swimming pools because the high levels of moisture in these environments are likely to cause a breakdown of the coating.
Off site application of pyroplast-HW100 is not recommended because of the risk of damage to the applied coating during transport to site.

preservatives
pyroplast-HW100 may be applied over most commercially available preservatives provided that they are allowed to dry out thoroughly and do not seal the timber surface.

stains
When a stained timber finish is required, only penetrating wood stains must be used. One single thin coat only must be applied to the timber and allowed to dry out thoroughly. Water based stainswill normally require at least 24 hours to dry out and solvent based stains will normally require at least 72 hours. Exact time for thorough drying will depend upon the environmental conditions. The stained surface should be lightly sanded before application of the pyroplast-HW100 to ensure adequate adhesion.

application rates
pyroplast-HW100 clear
