Zeroflame Wood-S
Zeroflame Wood-S is a waterborne intumescent coating that is designed to prevent the spread of fire on internal surfaces.
Best Uses
Zeroflame Wood-S has been successfully tested to European Standard EN13501-1, achieving B-s1, d0 on wood and wood based substrates with a minimum thickness of 8mm and density ≥338kg/m³, and on any substrates having fire class A1 or A2-s1, d0 (non-combustible substrates) with minimum thickness 6mm and density ≥338m³.
- Waterborne
- Dries to a matt white finish
- Can be overcoated with Zeroflame Topcoat W
Application
The recommended application method for Zeroflame Wood-S is either by brush, roller or airless spray. Roller or Airless Spray are the most appropriate methods for covering large flat areas.
Ensure that the surface to be coated is clean, dry and free from any oil, grease, or dust prior to application. If you are overcoating existing paint, any evidence of delamination between the exisiting coats, or between existing paint and the substrate, indicates that the surface is unsuitable for overcoating, and would therefore require all existing coatings to be removed.
Existing coatings that are found to be suitable, should be thoroughly abraded and all dust and debris removed.
Resinous timbers should be primed with a thin coat of Zeroflame Wood-S in addition to the full specification.
Zeroflame Wood-S should not be used on surfaces exposed to external conditions or to frequent exposure to moisture. If there is a risk of moisture penetration from the untreated side of the substrate, the reverse side should be sealed with a moisture resistant membrane. Adhesion and performance on anything other than untreated timber cannot be guaranteed.
