Patch Plaster Repairs

Patch plaster repairs are common in UK homes, particularly in older properties where wear and tear or previous repairs have failed. Whether a small dent in the wall or a larger area of damaged plaster, using suitable materials ensures a lasting and professional finish. In this guide, we’re using Dryzone Hi-Lime Renovation Plaster from Safeguard Europe, a versatile and breathable plaster ideal for patchwork in traditional and modern homes.

Hi-Lime Renovation Plaster is particularly suitable for UK properties with solid walls that require a breathable repair material. Traditional gypsum plasters can trap moisture, causing damp issues in heritage buildings or walls that need to "breathe." Hi-Lime, on the other hand, is a high-quality lime-based plaster that accommodates the needs of these walls while delivering a smooth finish.

Preparing for the Repair

Start by removing loose or damaged plaster from the area, ensuring the repair edges are neat. Clean the substrate to remove any dust, grease, or contaminants. If the underlying surface is highly absorbent, dampen it slightly to prevent the plaster from drying too quickly.

Applying Hi-Lime Renovation Plaster

Mix the Hi-Lime Renovation Plaster according to the manufacturer’s instructions, ensuring a consistent, lump-free texture. Apply the plaster in thin layers using a plastering trowel, pressing firmly to achieve good adhesion. Build up the plaster in layers for deeper repairs, allowing each one to dry partially before adding the next.

Finishing Touches

Once the plaster has dried, it can be sanded lightly to blend seamlessly with the surrounding wall. Because Hi-Lime is breathable, it’s an excellent base for finishing with breathable paints or lime washes.
