What Can MSL Timbercheck Treat?
MSL Timbercheck has been proven to provide effective fire retardation for untreated, uncoated wood in tests. Coatings (paint, varnish, etc.) should be removed by sanding or stripping before treatment.
What Regulations Does MSL Timbercheck Comply With?
MSL Timbercheck has passed BS EN 13823 and BS EN 11925-2 Single Burning Item Euroclass B-s1-d0 (s1 Smoke Production – d0 Flaming Droplets), which is equivalent to the UK “Class O” Building Regulations.
Euroclass certifications have been formally incorporated into UK building regulations. Regulators in the UK are legally required to accept them in lieu of national test methods (though these are also accepted.)

How Does MSL Firecheck Work?
When you apply MSL Firecheck to absorbent materials, it creates an invisible, fire retardant layer. The non-flammable properties of MSL Timbercheck become part of the substrate, which works to restrict ignition, slowing the spread of flame and potentially restricting the area affected by the fire.
MSL Timbercheck will not wash out from the surface of the substrate once dry and will not be converted into smoke when exposed to high temperatures. Any carbon char is restricted to the immediate area.
If treated material is exposed to temperatures of up to 1700 C it is subject to charcoal forming, which severely restricts the spread of flame.
Is MSL Timbercheck an Intumescent Varnish?
No. Timbercheck does not require an additional protective finishing coat.
Can MSL Timbercheck Treat All Types of Wood and Timber?
Wood moisture content should be 20% or less – typically the case for kiln-dried or seasoned wood. Timbercheck can treat all types of wood. We recommend testing a small sample or an inconspicuous area to establish absorption properties, variations to grain, texture, and possible colour change.
How Much Will I Need?
We recommend three coats. 270ml will give you a 3-coat coverage for approximately one square metre. Each coat should be applied with at least an hour apart.
- Our 1 Litre Trigger Spray covers 3.7 square metres
- Our 5 Litre Container covers 18.5 square metres
- Our 20 Litre Drum covers 74 square metres
- Our 100 Litre Drum covers 370 square metres
How Do I Apply MSL Timbercheck?
The treatment is supplied ready for use. You can apply it with a brush, roller, or by spray. (A mask should be worn while spraying.) MSL Timbercheck can also be applied through a dip or vacuum method, but the complete instructions should be read before beginning treatment.
Is MSL Timbercheck Corrosive?
Once dry, MSL Timbercheck does not react with galvanised steel (zinc), stainless steel, brass, gun nails, or zinc coated screws.
Where Can I Find a COSSH Safety Data Sheet?
You can view and print the Timbercheck COSHH Safety Data Sheet here.
Will I Be Able to Detect the Treatment Once Applied?
MSL Timbercheck is colourless and odourless. It should be practically undetectable.
How Long Does the Treatment Last?
MSL Timbercheck’s fire retardant properties are tested to NT 053 and NT 054 on a 20-year accelerated weathering cycle.
Can I Store the Product I Have Left for Use in the Future?
The product has a shelf life of several years. It should be stored upright and at temperatures above zero. If stored for more than six months, we recommend a gentle shake before application.
