Product Information

It does however have a few pitfalls, not the least of them being thermal bridging where the cold temperature of the masonry is transferred, via the plasterboard adhesive, to the inside of the plasterboard wall. This downside however, is nowhere near as common as the problem of trying to fix heavy objects such as large flat screen TVs and kitchen cupboards to a dot and dab wall. Remove any dust or debris from the hole before gently tapping the Corefix plug into place until the flange sits against the plasterboard.

Originally designed to safely secure wall hung kitchen cabinets Corefix fixings are now used to support any heavy loads on a hollow cavity wall including: Using a 4-inch wall plug, with the main body of the plug at a 10mm diameter, the Corefix wall plug is pushed into a 10mm hole. It is not pushed through the plasterboard however as the lip at the head of the plug will prevent that happening. It’s no secret, we love them! This hideous problem that has plagued us (and many many others) for many many years has now magically gone away thanks to Corefix. The diagram shows what Corefix can hold and 250kg is almost 39.5 stone or 3/4 averagely built people – That is very impressive indeed. How and Where do I buy Corefix?A screw, in this gap, is not supported and any heavy load applied to the end of it will cause the screw to bend. We will discuss this, and the wonderful advantage of Corefix a little further on. First, take a look at the video above where you will see just how powerful the Corefix dot and dab plasterboard fixings are. Why is Fixing to Dot and Dab Plasterboard a Problem? Corefix can be bought from most high street DIY stores today including B&Q, Screwfix and the similar.

We know the problem with fixing to dot and dab is the unsupported length of screw between the wall and the board. Corefix decided to keep it very simple and say that the solution is obviously to find a way of supporting it! And boy have they done that! Because it is bent, the downward force of the attached object starts to tilt outward as the image above shows. This stops the force being 100% downwards and moves it to an angle which, after time, starts to pull the screw out of the wall. If you need to secure deeper fixtures, then we recommend the Corefix 120 Dot and Dab Wall Fixing, which has a 120mm screw length. In 2017 statistics show that almost 80% of people are installing TV’s which range between 40 and 55 inches (Source Statisista.com). Drill a hole through the plasterboard and into the solid wall behind, ensuring the total depth is a minimum of 100mm.This is the number one problem with using ordinary plugs and screws to a dot and dab plasterboard wall.
