Plasterboard & Plastering Supplies: What Else You'll Need

In depth

Plastering is rarely just about the plasterboard itself. Achieving a professional finish requires a range of ancillary supplies that often get overlooked during initial purchase. While most kits contain the basics – some adhesive, a few application knives – it’s crucial to assess what else you'll need to achieve your desired result and avoid costly last-minute additions. Let’s consider the common categories and what might be missing from standard starter packs.

Firstly, there's the issue of surface preparation. Even seemingly smooth walls often have imperfections: small holes, uneven patches, or ingrained dust that will telegraph through the newly applied plaster. A decent selection of filling materials is vital. You’ll need a good quality joint compound – typically in both a ‘skin coat’ formulation for initial smoothing and a thicker ‘batt’ mix for larger areas requiring more support. Don't underestimate the volume needed; a single 25kg bag rarely covers a substantial area, especially when multiple coats are involved. Alongside this, you’ll need a variety of application tools – detailing knives in different widths (10mm, 18mm, 38mm) and a larger smoothing trowel for achieving a level surface. Consider investing in a small, dedicated ‘pointing’ knife for precise filling of gaps and corners; these are invaluable for a clean finish. Furthermore, a wire brush or sanding sponge will be necessary to scrupulously remove any loose particles before applying the first coat, preventing it from pulling away.

Next, consider protection – both of your work surface and the surrounding areas. Plastering creates a significant amount of dust and debris. A good quality drop sheet, ideally one that’s easily cleaned or disposable, is essential to protect flooring and furniture. You'll also need masking tape in various widths for creating clean lines and protecting adjacent surfaces. Don’t forget detailing sealant; this pliable material is used to seal around edges, corners, and fixtures like light switches and door frames, preventing plaster from migrating into these areas – a common issue if not addressed properly. A good quality brush or roller will also be required for applying the sealing compound, ensuring a consistent and professional finish.

Then there’s the question of finishing and repair. Even with careful application, imperfections are bound to occur. Having a selection of fine-grit sandpaper in various grades (120 grit, 240 grit) is crucial for smoothing out minor blemishes between coats and for final surface preparation before painting or decorating. A small sanding block will provide support and ensure even pressure. Additionally, you'll need some plaster mixing buckets – plastic ones are best as they’re easy to clean – along with a mixing paddle to thoroughly combine the plaster powder with water. Accurate measuring is key to achieving the correct consistency, so having a decent sized measuring jug or cup is also recommended.

Beyond the immediate application process, don't overlook tools for cleaning and maintenance. A stiff-bristled brush will be invaluable for removing excess mortar or plaster dust from walls and tools. A damp sponge and clean cloths are necessary for keeping your work area tidy and preventing the plaster from drying out too quickly. Having a dedicated container for rinsing sponges and brushes is highly recommended to avoid contaminating other areas. Finally, consider investing in a small toolkit containing essential items like pliers for removing nails or screws from walls before starting, and a utility knife with replacement blades for cutting masking tape or drop sheets.

Finally, think about longevity – particularly if you're undertaking a larger project. Having extra bags of joint compound readily available is sensible, as it’s easy to underestimate the amount required, especially when working on uneven surfaces. Furthermore, consider purchasing a small container of plaster levelling mortar; this can be used to address significant height variations in walls before applying the final coat of plasterboard. A good quality adhesive for securing the plasterboard to studs or joists is also important – ensure it's suitable for use with plasterboard and compatible with your chosen fixing method. Remember, thorough preparation and having the right tools on hand will significantly improve the quality of your work and reduce the risk of costly mistakes or rework.
