Does the thought of tape and joint plasterboard to the ceiling intimidate you? Don’t worry! Jérémy Poupart, our technical advisor at Beissier, will guide you step-by-step on how to apply jointing strip to a plasterboard ceiling using Prestonett J8h, a normal-setting powdered joint treatment compound.

Here are the answers to the essential questions you might have about ceiling plastering!

1 – What materials should you use?

Plastering requires some essential tools. Here’s what you’ll need:

• Stepladder
• Tarp
• Putty knives (one 20 cm and the other 10 cm will suffice)
• Vacuum cleaner
• Utility knife and/or drywall shears
• Joint tapes
• Powdered or ready-to-use paste compound for joint treatment (the choice depends on the project size, temperature, and speed of execution)
• Sandpaper with 150-180 grit (preferably use an electric sander to reduce fatigue).

2 – What are the key steps before plastering a ceiling?

Applying plaster requires preparation. Always ensure to thoroughly assess and recognize your surfaces. Ensuring that the site is healthy, clean, dry, and non-powdery is crucial for wall adhesion. The preliminary steps for plaster application depend on your surfaces: plaster, concrete, reinforced cement boards, previously painted surfaces… Follow the expert advice of Jérémy Poupart to properly prepare the surfaces before applying the plaster.

3 – What about the finishing touches?

On horizontal surfaces like ceilings, the working time will be longer. Jérémy Poupart advises using a slow-setting compound like Prestonett J8h, which is smooth, easy to sand, and simple to prepare, ensuring excellent adhesion. Follow the steps in our video to see the full application process!
