Can construction adhesive replace screws?

On cornice, skirting, panels and decorative elements, yes — high initial grab holds the piece as it is placed. Structural and heavily loaded fixings still need mechanical fasteners.

Which surfaces can it be used on?

Timber, concrete, plaster, plasterboard, metal and most plastics. If neither surface is porous, choose a moisture-curing (hybrid or polyurethane) product.

How is a chemical anchor applied?

Drill the hole, clear it completely of dust, inject the resin from the bottom up, and set the stud with a twisting motion. Not cleaning the hole is the most common error and lowers load capacity.

How long until full strength?

The grab is immediate, but full strength can take 24 hours or more depending on thickness and conditions. Support heavy pieces for that period.

Construction adhesive and chemical anchors

A high tack adhesive grabs hard enough to hold the piece the moment it is placed, replacing screws and nails on cornice, skirting, panels and decorative elements. At least one surface should be porous, or the product should be one that cures on moisture.

A chemical anchor injects resin into the hole to bond the stud chemically to the substrate; applying no expansion force, it suits small edge distances and perforated brick.

The surface must be clean, dry and free of grease.
Support heavy pieces temporarily until cure.
Clear the anchor hole of dust completely.
Between two non-porous surfaces, choose a moisture-curing product.
