The Dryzone Drygrip Adhesive is a salt and damp resistant adhesive glue. It is intended for use when fixing plasterboard directly onto a masonry substrate, as its adhesive capabilities ensure a strong bonding strength. The adhesive is highly resistant to moisture and so is generally used after the wall has been treated for rising damp using the Dryzone Damp-Proofing Cream, although it can also be used as a general adhesive.
Even after treatment, rising damp can still have an effect due to the presence of residual damp. This can damage any new render systems that are installed, and so it is important to safeguard the new finish against the risk of damp. Dryzone Drygrip Adhesive is designed to function within a drylining system, reducing the need for materials that are susceptible to damp. The adhesive safely secures plasterboard directly to the substrate without the need for timber battens, but still leaves an airgap between the plasterboard and the wall to allow for the wall to dry out fully without affecting the new render.
What is Rising Damp?
Rising damp is a common problem in older properties where a DPC hasn’t been installed, or in properties where the DPC has failed. Rising damp is caused when water is drawn from the base of the wall upwards by capillary action. It causes problems within a structure as it can result in structural instability as well as persistent damp patches on the internal walls and floors. The only true solution to rising damp is by installing a DPC, however this is difficult to do retrospectively. This is why the Dryzone range is so effective at putting a stop to rising damp.
Applying Dryzone Drygrip Adhesive
- Before using the Dryzone Drygrip Adhesive, the substrate should be clean and free of plaster, dust or paints.
- Rising damp should be treated using the Dryzone Damp-Proof Cream.
- Prime the wall using the Dryshield cream – apply in a single coat using a soft brush.
- Prepare the plasterboard by measuring and trimming to size. A gap of 12mm should be remaining between the base of the board and the floor.
- Insert Drygrip Adhesive into the applicator gun, cutting it open. Trim nozzle to 10mm diameter size hole.
- Dab Drygrip Adhesive directly to the plasterboard using a dryzone high viscosity gun.
- Allow for even and regular spaces between adhesive dabs – 1-2 Drygrip tubes per sheet of standard size plasterboard.
- When application is finished, remove nozzle cap and clean gun of all adhesive. If adhesive is left over in the gun, the nozzle should be covered over with tape.
- Fit the plasterboard to the wall, allow an airgap of 10mm.
