What Is Plasterboard Joint Filler? 

Plasterboard joint filler, also known as drywall compound or joint compound, is a paste-like substance specifically formulated for filling and concealing joints, gaps, and imperfections in plasterboard installations. 

It is applied over the joints between adjacent plasterboards to create a seamless surface ready for further finishing treatments.

Plasterboard joint filler is primarily used to create smooth, seamless, and even surfaces on walls and ceilings before painting or wallpapering. 

This material has a wide range of applications in building construction and offers several benefits that make it a popular choice among builders and contractors.

We stock solutions from big names such as Gyproc (a joint filler which is designed for bulk and secondary filling of plasterboard joints) among many others.

Frequently Asked Joint Filler Questions

How Do You Mix Joint Compound?

Make sure to read the instructions on the label of your Joint Compound to determine the appropriate amount of water required for mixing.

Using too much water can make the compound too diluted and ineffective, while using too little water can result in a thick and pasty compound.

What Is The Working Time of Joint Filler?

Joint filler typically has an extended working time, allowing users to apply and manipulate the material before it sets. 

The working time may vary depending on the specific product and environmental conditions, so it's essential to follow the manufacturer's instructions for best results.

The compounds used to fill the joints during construction are typically products that harden through a setting process, rather than relying on humidity. 

These fillers are applied manually (hand application) and have minimal shrinkage as they harden.

Is It Necessary To Sand Joint Filler After Application?

Yes, sanding joint filler is typically required to achieve a perfectly smooth and uniform surface. 

Once the joint filler has dried, it can be sanded using fine-grit sandpaper or a sanding block to remove any excess material and create a seamless result.

Does The Weight of Joint Filler Impact Its Application or Drying Time?

The weight of joint filler is generally not a significant factor in its application or drying time. 

The consistency and composition of the filler are more important considerations. It's crucial to follow the manufacturer's instructions regarding mixing ratios and application thickness to ensure optimal results.
