THOMSIT TF 310 is an alkali-resistant glass fiber mat for the reinforcement of THOMSIT leveling compounds when used on:

• Substrates with cracks and dummy joints up to 3 mm width where little movement is expected
• Substrates at risk of cracking
• Slightly vibrating substrates or substrates at risk of vibration damage, e.g. boarded floors, chipboards (P4 to P7) and OSB boards (OSB/2 to OSB/4)
• Mixed substrates

In combination with recommended THOMSIT leveling compounds, TF 310 can also be used to produce heavy-duty floors in commercial and industrial facilities.The fibers are bound with a special binder, which dissolves on contact with suitable THOMSIT fillers. As a result, the individual fibers are optimally coated by the filler and strengthen the leveling layer, thereby increasing the flexural strength of the composite system and reducing shrinkage stresses. THOMSIT TF 310 can be used in combination with THOMSIT TF 320 glass fiber strands for repairing cracks up to 5 mm width.
