Fixing To Plaster Board

There are a selection of fixings available specifically for plasterboard including: the Redidrive; nylon toggle fixings; hallow wall anchor plasterboard fixings; rubber anchor nuts; spring toggle of butterfly plasterboard fixings and simple lightweight plastic fixings for plasterboard.

You cannot use ordinary wall plugs for this as they expand as you screw them. The plasterboard is soft and widens the hole you screw into. In no time this will come loose.

Self drive plasterboard fixing

The Redidrive – one of the strongest plasterboard fittings.

A pilot hole is drilled (2 to 3mm) and the Redidrive bottom section is screwed into the hole. This is without the screw top section as the Redidrive has a slotted head.

You don’t have to drill a pilot hole as the screw has a pointed shaft, however there is a chance that it may hit a piece of timber or something. If this does happen the redid rive will snap and leave you with an unwanted hole.

Drilling the small pilot hole will prepare you if there is anything behind the board, it will also prevent an movement in the Redidrive when you insert it.

We advise that for plasterboard, you use one of the fittings from the above list and do not use ordinary wall plugs.

FIXING TO MASONRY WALLS

Masonry includes brick, stone and block walls or concrete (anything that a mason puts down)

Drilling into masonry:

If masonry is in good condition the surface will be hard, to et through this surface you will need an electric drill with hammer action (no less that 500W). These are available to hire or to buy. Discuss the job with your hire shop and they will be able to advise the best tool for you to use. You will also need to buy masonry drill bits of the correct hole size.

Drill bits designed for concrete or brick will have a flat cutting section at the end which is slightly wider than the shaft of the drill bit. You can see in the below image that the top drill bit has this flat cutting section at the end compared to the bottom one.

This allows the drill bit to cut its way through the masonry or concrete and the excess can escape through the grooves back to the opening of the hole. Cheap drill bits will blunt very quickly and it’s much more advisable to go for good quality!

If you have a very hard surface and you would like to drill a large hole, it’s much better to drill a smaller hole first and then increase the size. This will be a lot easier on all of the drill bits and will save you from burning out your drill.

Fixing to masonry:

You cannot screw directly onto brick walls, block walls or stone so you must first of all drill a hole and then insert something that can be screwed into and will hold it in place.

The best way to fix on all masonry that is in good condition is by using plastic wall plugs. They expand against the wall inside the hole that you’ve created to ensure a nice tight and secure fit.

Plastic plugs are indeed the best and easiest was to  his things onto perfect walls that are drilled easily, firm, strong and thick.

Colour coding for wall plugs

Wall plug sizes are usually sorted by their colour, brown, blue, yellow and red. You will also see many grey and other coloured plastic plugs on the market and each has a job to do, but for the purposes of this project and to assist you in getting a good fixing to a brick, block or concrete wall or ceiling, we will just deal with the four major wall plug colours.

Bricks

With bricks we would say that it’s best not to screw into the same brick more than once or maybe twice. Try to always place the item (bracket or flange) so that it’s lying across two or three bricks and spread the screws out between them. This is so not to put too much pressure on one brick, causing crumbling or weakening. Make sure you avoid drilling onto the mortar and try and drill directly onto the brick as it is slightly stronger.

Problems and issues

Occasionally you will have a wall that is in not so good condition, the bricks could possibly be crumbly ect.

With crumbly bricks the best thing to do is use resin anchors and resin fittings. These are a fantastic way of fixing to masonry.

The basic idea is you can drill a hole, clean it out and then fill it with injection resin, put the stud in and then leave it to set. All of this assumes that it’s compatible with your type of fixing though!

Because resin fixings do not rely on expansion force, they can be used in places where traditional fixings that rely on expansion cannot be used such as close to the edge fixing or crumbly walls!
