It can be applied on various smooth building substrates such as timber, OSB boards without additional surface treatment. The surfaces must be dry, free of dust and solvents such as grease or oil. We recommend the use of PRIMER for rough surfaces such as rough OSB boards. After the separation film has been partially separated, the tape can be applied easily and precisely at the corner point without further corrections. The sealing is completed by separating the remaining film and adhering the tape to the support. Once the tape has been applied, it is recommended to use the special roller RLL45 to obtain a perfect application.
