How does msl Timbercheck work?

Treating absorbent materials with msl Timbercheck creates an invisible, fire retardant layer. msl Timbercheck has non-flammable properties, which become part of the substrate, restricting ignition and the spread of flame. It will not wash out from the surface of the substrate after drying, it is not converted into smoke when exposed to high temperatures, and carbon char is restricted to the immediate area. Materials treated with msl Timbercheck when exposed to temperatures of up to 1700 C are subject to charcoal forming, severely restricting the spread of flame.

Is msl Timbercheck an intumescent varnish?

No, unlike intumescent systems it does not require an additional protective finishing coat.

Can msl Timbercheck treat all types of wood and timber?

Timbercheck can treat all types of wood. Wood moisture content should be 20% or less. We would recommend testing a small sample or inconspicuous area of the substrate to establish both absorption properties, unwanted variations to grain, texture and possible colour change.

Are there any types of wood and timber msl Timbercheck will not treat?
