With the Soudal professional adhesive trowel B11, you create a solid foundation for your parquet installation. When bonding large wooden floorboards and parquet formats larger than 60 x 300 mm, an even adhesive bed is essential to prevent hollow sounds and voids beneath the floor. Thanks to the coarse B11 notch pattern, you consistently achieve the correct adhesive bed height and reliable back-coverage, even on sand-cement or anhydrite screeds. Its practical 18 cm working width gives you full control for smooth, accurate and efficient spreading across any subfloor.
