Using Fillers – One of the cheapest and economical materials to use in carrying out small scale repairs to walls is an interior filler. This is a very fine powder that is simply turned into a paste by adding water.

The outcome from using this paste is that it bonds remarkably well to plaster and plasterboard surfaces. It also dries really quickly and can then be sanded into a smooth finish.

A little trick for mixing your filler is to use a small bowl and literally trickle the appropriate amount of water into the bowl with the powder in it stirring the solution as you go until it turns into a paste of a thick mouldable consistency. The filler will harden as soon as it turns into a paste so time really is of the essence to get it on the wall! You’ll have around 30 minutes before the filler goes completely hard.

You can also buy pre-mixed filler just make life a little easier, the same principal discussed below applies! A great supplier of pre-mixed filler is Wickes DIY.

Filling Cracks – As well as the power or pre-made filler solution you”ll have to make sure you possess a filling knife or something similar.

One you are prepared and you have our filling knife to hand and your pre-mixed filler solution and your ready to fill some cracks (we’re sure there’s a joke here somewhere) you’ll need to use the corner of your knife to rake out the crack on the wall and rough the area up a bit in order to get a good key for your filling solution to bond to. Getting an old paintbrush is also handy to remove and dirt or debris from the crack, again preparing the wall in such a way will give you a better finish.

Once the crack is clear from debris and has a good key you’ll need yo wet the crack with a little water. You can apply the water with your old paintbrush that you used to initially clean the crack with. Now, with the crack a bit wet, apply some of your filler buy using your knife to the crack being as even as you can, use the knife to remove any excess filler. You’ll now have to let the filler harden for about an hour and then use the fine sandpaper to smooth the filler on the wall bringing it to an even finish. You should be aiming for a finish that is consistent and smooth.

Filling Holes – We are all aware that holes can be a big problem on walls. Those little screw or nail holes soon add up and can turn your room into a bit of an eyesore. We treat holes in walls very similar to filling cracks in walls buy firstly removing any unwanted dirt or debris from the area to be treated, use your old paintbrush for this.

With your filling solution at the ready you’ll start off buy cleaning the area as mentioned above and then filling the hole(s) in question. You’ll first need to wet the hole as this prevents the filler from hardening too quickly and cracking in the hole. You’ll then get some filler on your filling knife (or similar) and then literally pressing the filler into the hole using small chunks of filler until the hole is completely filled. Fill the hole in the wall and work the filling solution until it’s smooth with the wall, i.e. you can’t see the hole any more just filling solution that is flush with the wall.

If you have a large hole in the wall that you need filling then the best advice is to complete this in two applications. Doing so will prevent any thick layers of filler slumping or dripping down the wall. Simply let the first layer harden and then apply the second laer to complete the job.
