Our top tips

  • Our first tip that any plasterer worth their money will tell you, is any surface waiting to be plastered needs to be clean and any previous bits of wallpaper need to be removed to ensure a secure, smooth finish.


  • It’s vitally important you check out and then appropriately manage the suction of the wall as it can make all the difference between the right result and a poor finish.


  • Exceptionally porous masonry will cause the plaster to dry out too fast, which can lead to potential issues with the finish as you probably won’t have time to flatten out. If this is the case, wet the wall before you start to safeguard against the plaster falling away.


  • Low suction walls won’t suck the water particles out the plaster very quickly meaning the use of a bonding agent is required such as PVA diluted with a bit of water. Sand can also be added to the mixture to give added adhesion. The exact mix varies from plasterer to plasterer but 4:1 is a general rule of thumb.


  • Apply two coats of backing mixture and ensure it is flat. The skim finish can be smooth, but the backing mixture needs to be flat for this to happen.


  • Ensuring your surface is ready to be plastered; plaster won’t stick to just any surface and you don’t want it to start falling away.


  • We’ve said this before and we’ll say it again, “keep everything clean”! It makes all the difference as you don’t want your plaster to go off due to dirty buckets, trowels etc.


Plastering tips for the skim coat

As a general rule of thumb, there are six stages to applying the skim coat.

  • start with an even layer / coating of around 2mm.

  • When this coat has gone ‘tacky’, or when you cannot remove the whole covering with your hand, just a little bit, then run your trowel over flattening all the ridges and bumps that stick out over the original 1-2mm.

  • Next, apply a second coat of as close to 1mm as possible.

  • After that’s applied, trowel it so it’s nice and smooth and when ‘tacky’ go over every hole/dent and to get it as smooth as you can.

  • Leave it for a while and as the plaster starts to harden most of the ridges/trowel marks will even out on their own.

  • If there’s any issues such as blistering as the plaster drys they should sort themselves out.

Dry lining and Rising Damp

drywall mold

We often get asked about dry lining a wall where rising damp has previously been treated with a damp proof course. The relationship between dry lining and rising damp is one to be carefully considered, as salts dragged up from the ground become present in the masonry and plaster. These salts increase the ability of the wall to absorb water, which can be worsened by other effects such as condensation and humidity.

The below information may help answer some common questions around this:

The issue of damp is a complex one. When completing dry lining, you may regularly find a damp proof course has been used to treat damp. Damp exists in buildings when moisture enters the structure; predominantly through humidity / condensation, rain penetration and rising damp, and can lead to masonry or plaster smelling.


Humidity and condensation is borne out of a lack of ventilation within a property, resulting in water vapour becoming trapped within porous walls, known as interstitial condensation. This can usually be spotted through steamed up windows. If condensation and humidity is causing walls to look damp, a dehumidifier should be installed to combat the problem.


Rain penetration occurs most often in single-skin walls. It can also happen in cavity walls, too, through the process of tracking across wall ties, so keep an eye out. Brickwork with cracked pointing, and any exposed porous stones and bricks can all lead to issues. A simple re-pointing of the external walls can fix this.


Indoor moisture commonly starts at the base of walls, potentially from defective ground and surface drainage, however this can also be caused by heightening ground levels and the failure of ground drainage systems. Leaks and flooding from defective drainage and plumbing are also sources of moisture occurring on the base of walls in buildings.

When confronted with the issue of having to dry line a previously damp wall, after a damp proof course has been used to treat damp, double check the masonry to make sure the damp proof course is doing its job. After this, you can use our Gyproc plasterboard along with our Thistle Multi Finish plaster to ensure a good finish.

Frame Fixings vs Hammer Fixings: The Pros and Cons.

Are you unsure of the difference between frame fixings vs hammer fixings#? Don’t worry, we’ve got you covered! To begin with though, let us remind you of the benefits of through fixing more generally. The biggest and most important reason for through fixing is that removes any worry of damaging the chosen surface. Plus, it removes the need for marking and re-positioning.

Hammer fixings are specifically designed to have the screw hammered in. The threads share some similarities with one way valves, they fold over when the fixing is hammered in but spring back when the trough is detected in the thread. The minor screw on them is only on there to aid removal.

The positives are that it’s quicker to fit as hammering is a lot quicker than screwing in, and there’s no damage done to the thread. No screwdriver is needed either and when you’re onsite this is always a bonus. The cons are that they are more widely seen as

Frame fixings are more heavy duty and often used for attaching uPVC, wood and metal frames to wood or PVC masonry. There seen as a relatively stress free spacer assembly screw for wood metal and plastic window frames.

How to spot a Frame fixing

Always wanted to know how to spot a frame fixing? Well here’s the answer! A through fixed frame can usually be identified, as the head of the fastening will usually be visible on the surface of the frame. This is often referred to as the visible fixing. Otherwise, you can’t spot a frame fixing as the head of the fastening is hidden behind a strip which is set into the face of the frame section. This is known as concealed fixing.
