Nida BOARDFIX

Plasterboard bonding coat, pre-coated with gypsum-based mineral additives and professional grade additives, characterised by increased adhesion and plasticity. In combination with water, a homogeneous, pink paste is formed, with extended working time and prolonged levelling time, representing the safest solution for the joining of gypsum-based plasterboards.

Further information

Applications:

  • for joining of plasterboard panels to BCA, brick, concrete, plaster surfaces (cement, lime cement, gypsum);
  • for joining insulating panels, repairing cracks or filling joints thicker than 3 mm;

Benefits:

  • very good adhesion to the substrate
  • high mechanical strength
  • long working time

Instructions for use:

The support must be dry, without dust and free of oil stains.

Preparation
NIDA Boardfix is gradually dispersed in the clean water required for the mixture, then it is manually or mechanically mixed until the complete homogenization of the paste.

Application
Before placing the adhesive, check the support flatness beforehand; the opening between the support and the plasterboard should be minimum 5 mm and maximum 25 mm in order to obtain the necessary cohesion.
The first step consists in lining out the future surface contour by means of the lead thread, measuring tape and oxide thread. Apply the adhesive cakes on the back of the board, disposed in 10 points per square meter, with a diameter of 10 cm, at distances of 30 cm on the board width and 40 cm on the board length.
After completing the material application, fix the board on 2 spacers of 1 cm, which will support the board on the mounting. Then fix the board to the support for bonding, taking care to obtain a continuous surface. The flatness is acquired and corrected by means of the straight edge by pressing and slightly tapping the board vertically, horizontally and diagonally.

Handling and storage:

Keep the bags on wooden pallets, in covered and dry placed, protected from atmospheric factors.
In case of partial use, close the bag carefully for further use.
