Bona U310 is a polyester spunbond fleece that reduces the stress transferred to the subfloor when laying prefabricated parquet, solid parquet and laminate on old parquet or other critical sub floors.
Hairline-/shrinkage cracks in mineral sub floors can be bridged up to a width of 0.5 mm. Due to its high tear resistance the decoupling fleece reduces tensions from the sub floor and keeps them away from the subsequent top layer.
KEY BENEFITS• Easy to cut • Stress relieving • Suitable for use with various Bona adhesives • DIBt approval
