Plastering a wall may seem like a straightforward task, but achieving the perfect smooth finish can be a challenge. Have you ever wondered just how smooth your freshly plastered wall should be? This intriguing question goes to the heart of the matter, as the level of smoothness can dramatically impact the final appearance and quality of your plastering work.
According to the first source, you can’t start painting new plaster directly and instead have to take steps to seal the plaster so you can get the colourful finish you want. The very first thing you need to do when painting new plaster is to let it dry. A week should be long enough to let it completely dry out and for all damp patches to disappear. Once the plaster is dry, it should be light with no dark spots and a consistent colour and appearance throughout.
The second source mentions that the plasterer may have put the plaster on old and potentially uneven walls (old house with old plaster that had lots of cracks and dents but wasn’t crumbling) with no plasterboard, which could be the reason for the uneven areas and bumps that became visible after painting. The third source suggests using an angle headed scraper with a razor sharp blade to run over the surface and then touching up with Polyfilla to address any trowel lines or raised areas.
Preparing the Wall for a Smooth Finish
The first step in achieving a smooth wall surface after plastering is to let the plaster dry completely, which can take up to a week. During this time, it’s crucial to put down dust sheets and use tape to protect any fixtures and fittings, as applying a mist coat can be a messy process.
The mist coat, which acts as a primer to help the topcoat adhere properly, is made by mixing three parts emulsion with one part water. This mixture should be applied using either a roller or a paintbrush, working in smooth upward motions until the entire wall is covered. It’s important to address any drips or streaks immediately to prevent them from drying and ruining the finish. Once the mist coat has been applied, it should be left to dry for 24 hours before the topcoat is applied.
Plastering Techniques for a Smooth Wall Surface
For those seeking a smooth wall surface after plastering, the third source suggests utilising an angle-headed scraper with a razor-sharp blade to run over the surface. This technique can help address any trowel lines or raised areas that may have occurred during the plastering process, thereby achieving a smoother finish and ensuring an even surface when painting.
Furthermore, the first source emphasises the importance of protecting the surrounding area while the plaster is drying. It recommends placing dust sheets and using tape to safeguard any fixtures and fittings, as applying a mist coat can be a rather messy endeavour. The mist coat, a mixture of three parts emulsion and one part water, serves as a primer to enhance the topcoat’s adherence. This coating should be applied using either a roller or a paintbrush, employing smooth, upward motions until the entire wall is covered. Any drips or streaks should be addressed immediately to prevent them from drying and compromising the final finish.
