For “dot and dab” using the DriLyner system, each bag will fix approximately 2 boards (1200mm x 2400mm). Dabs should be applied in a regular pattern in accordance with BS 8212 and BS 8000: Part 8 to give a minimum area of contact between board and background of 20%.
Please refer to WHITE BOOK Chapter 07 Section 03 Page 14 & Page 16 for more details. Page 16 shows a wall elevation with an example dab pattern. Also please refer to the SITE BOOK.
