Description

Thermoguard Fire Varnish BS Class 1/0 & EN Class B s2 d0 System

Thermoguard Fire Varnish BS Class 1/0 & EN Class B System is a clear fire retardant varnish for interior and exterior timber surfaces. These packs have been created to help users ensure they are purchasing sufficient product for their project. Each pack contains the correct amount of basecoat (Fire Varnish Basecoat) and topcoat (Fire Varnish Overcoat) to ensure protection is achieved inline with the manufacturers recommendations to the respective area in question.

The Thermoguard Fire Varnish system is specially formulated to provide a tough, durable finish to internal and external wood. Clear or stained finishes enhance the natural beauty of the wood while fire protecting surfaces. The Fire Varnish Overcoat in Matt or Satin finishes provide protection against UV and wear.

When exposed to fire, the Thermoguard Fire Varnish system expands to create an insulating barrier, protecting timber surfaces from flames, heat and oxygen and suppressing emission of deadly smoke & gasses.

Previously Varnished and Stained Surfaces or Wood Preservers

The Thermoguard Fire Varnish System can be applied over firmly adhered standard clear varnish. For existing stained varnishes, stain coatings, old fire coatings or if in doubt, contact our Technical Department on 0113 2455450.

  • If preservatives are required, use rapid drying clear non water repellent grades*.
  • For tanalised or other preservative treatments, contact our Technical Department.

*Allow adequate time for stain or preservative fluids to escape before applying the Thermoguard Fire Varnish System.

Application to OSB/Sterling Board

This is a board made of chips of wood glued together to form a hard non-decorative board. If it needs fire coating, Thermoguard Fire Varnish or Timbercoat System can be applied to it. However we first recommend a test is carried out by applying a small amount of the proposed coating to the board to check for "cessing" / "cissing" (where coating gathers together in lumps and may leaving bare patches between). If this occurs the board should be degreased/cleaned and allowed to dry before testing again - if this still does not provide a satisfactory application please contact our Technical Team for further advice on 0113 2455450 (option 2) or send a message to [email protected].

Fire Test Standards and Certification

  • EN Class B s2 d0
  • BS Class 1 and Class 0

questions James on 2019-05-23 22:27:28
Question: 

Can this be applied over Polyx oil or Wood Wax Finish?

Answer: 

No, neither can be used, see notes below on existing coatings before the use of Thermoguard Fire Varnish BS Class 1/0 & EN Class B System;

Recommended: Penetrating Wood Dyes / Spirit Stains based on low flash solvents (eg Xylene, Toluene, Alcohols) Benefits are – Quick drying, do not seal wood.

Acceptable: Penetrating Wood Dyes based on Water (not water repellent). Precaution - wait for all water to come out of wood before overcoating.

Usable with Caution: Nitrostain, White Spirit Penetrating stains (single coat of matt only). Precautions - Allow to dry thoroughly (up to 2 weeks for white spirit), degrease with warm detergent solution necessary with some sanding required if a solid film has been formed.

Not Recommended: Stains containing Water Repellents, Waxes, Oils, Coal Tar Distillates / bye-products, satin or gloss woodstains or other stains which seal the wood or stains that deposit a weak film of underbound pigment. “Home recipes” combining stains and lacquers. Note: Consult the Technical Team if these have been applied already or if in doubt.

Compatible Pre-Existing Coatings: Long oil Varnish, Yacht Varnish or Polyurethane Varnish - Require thorough sanding to give a “key”, non water-repellent organic solvent preservative (provided thoroughly dry). For others please consult the Technical Team.

Incompatible Surfaces: Photographic faced hardboard, CCA “Tanalised” or water-repellent grade preservative treated timber. Emulsion paint, old “1st generation” type clear fire coatings*

Paints: Paint should be overcoated with Thermoguard Timbercoat BS Class 1/0 & EN Class B System in your chosen BS or RAL colour. Paints cannot be successfully coated with a clear fire varnish because – adequate abrasion of hard or smooth paint damages the colour, while softer emulsions & acrylics cause varnish to craze or shrivel.

*If these may be present, contact Technical Team for specific advice, tests etc.
