With Botament building boards uneven substrates are quickly, easily and efficiently made level. Substrates that have been levelled with Botament building boards, are ideal for receiving subsequent tile covers.
In dry areas joints should be reinforced with joint reinforcement tape GS 12 and filled with M 21 Classic.
On even substrates building boards can be laid by bonding across the whole area.
On uneven substrates building boards that are less than 20 mm thick must additionally be secured with dowels as well.
