The JACKOBOARD® washers are used to fix JACKOBOARD Plano boards to substrates in many applications. No surface preparation is required. If the washers are used in a wet area, then sealing of the screw penetration will be required. This can be done with our wet fleece tape or by using our Boardfix and flattening off with a pallet knife.

Due to the JACKOBOARD® versatility, the construction boards can be used in a variety of applications. • The washers are designed to be used on stud walls, ceilings and timber floor applications • Stud wall application – washers to be screwed into stud at a minimum of 8 fixings p/m2 • Washer to be tightened/hammered home until the surface starts to crush the cementitious coating so not to be sitting proud and provide correct torque to fix the construction board • Washers are to be used with JACKOBOARD® 4mm diameter screws • Galvanised washers are suitable for dry and wet areas • Timber floor applications – screw washer fixings are used to help aid any expansion/contraction within the floor construction. • BBA tested to hold 100kg p/m2.
