THOMSIT TF 201 Sheet Membrane is a dimensionally stable separation course, always loose lay, to ensure the reliable installation of PVC and CV sheeting on difficult substrates. These include for example:

• cement screeds up to 6 % CM residual moisture
• calcium sulfate screeds (anhydrite) up to 2 % CM residual moisture
• old stonewood and magnesite screeds

The membrane can also be used on substrates that are not ready for covering but load-bearing, e.g.:

• floors contaminated with wax, grease, chemical residues, old paint or other coats
• floors with residues of sulfite liquor and bitumen adhesives.

Additionally, THOMSIT TF 201 can be used to protect substrates that are worth preserving, e.g. terrazzo slabs or artificial stone floors.
Suitable for use on heated floors if there is no exposure to rolling traffic.

Do not use on subfloors with high-low textures and on mineral oil contaminated floors.

Use THOMSIT T 590 Quick-Lift® for installing textile flooring.
