What is dry lining? – A Comprehensive Guide

What is dry lining?

Let’s start with the basics! Dry lining is a type of internal insulation, which involves attaching ready sheets of plasterboard to a wall. The process doesn’t require the use of water, so it’s considered a quicker, cleaner and easier solution.

What is the dry lining process?

• Choose the right materials: Plasterboard comes in different sizes, so your dry lining contractor will have to pick the right thickness first. Then, it’s a question of calculating how much plasterboard you need.
• Identify the right technique: Dry lining is usually applied to bricks, but it can also be added to wooden or metal walls. Depending on the area, a decision will have to be made as to whether it’s best to use glue, screws or nails.
• Evaluate the need for added insulation: If you are looking into dry lining, you probably want to improve the energy efficiency of your property. Sometimes, adding an extra layer of insulation is needed.
• Secure the plasterboards: One of the trickier parts of the dry lining process is securing the joints with tape and a compound.
• The finishing touches: Once the main body of work is done, a finish is applied and the boards are sanded to even out the surface before you can start decorating.

Popular dry lining techniques

There are various ways to fix plasterboard to a wall. Here are the most popular dry lining techniques used both by professional plasterers and DIY dry lining enthusiasts.

• Dot and Dab: This is one of the most popular dry lining techniques, as it’s less messy and sets more quickly. Basically, the way it works is that dabs of adhesive are placed along the wall as a method of attaching the plasterboard.
• Tacking: This is when nails are used to attach plasterboard to metal or timber walls.
• Screwing: Usually, screws are better for attaching plasterboard than nails and when screws are used the process is called screwing.

Dry lining benefits

If you are wondering if dry lining is any good, here are some of the main benefits of choosing dry lining for your home, office or shop.

• Less time-consuming. Undoubtedly, dry lining is faster to install. Without the drying time associated with wet plaster, it’s a quicker solution.
• Reduces risk of hairline cracking. The process used to fix dry lining to a wall doesn’t require drying, therefore the danger of hairline cracking is smaller.
• Prevents condensation. If done correctly, dry lining can offer insulating qualities. A good professional plasterer will place a thick layer of insulation behind the plasterboard to work as a vapour barrier to reduce condensation. It also helps make your space warmer.
• Better for interior design. Dry lining can be used to conceal those annoying loose wires hanging from the wall. Plus, you won’t have to worry about uneven walls ruining the look of your property.

Common problems with dry lining 

Like any other process, dry lining requires a certain level of skills to be executed correctly. Some of the most common issues you can encounter when dry lining include:

Insufficient framing around corners

In order to fix the edge of the plasterboard, you need the exposed framing around the corners to be minimum 1 mm thick. However, in many cases, it’s non-existent or too small, hence additional framing will have to be put in place.

Plugs not fitting

No matter how carefully you measure your drywall, there is always a chance that there will be a socket that somehow doesn’t fit as it should. If this is the case, adjustments will have to be made before the plasterboard is installed on the wall.

Cracks 

If you install dry lining too close to a door or window opening, this could cause cracks to appear in the future.

Technical difficulties

Dry lining may sound easy but there are many details that you may miss if you don’t have experience with the process. From difficulties placing screws due to bad framing marking to insufficient edge support, installing corner beads the wrong way round and using incorrect measurements when cutting the plasterboard, there’s a whole list of things to take into consideration.

Issues with airtightness

Airtightness or how resistant your house is to draughts is an important part of insulation. When installing plasterboard, you can face issues with maintaining the integrity of the seal around the room, especially when a dry lined wall meets another type of wall. It requires careful planning and designing to get this right.

Don’t let this put you off though! Dry lining is a great solution, used by millions of people across the UK. Most of the issues we discussed can be avoided if dry lining is left to a professional. This is why many people turn to dry lining contractors for help.
