A Beginner’s Guide to Quality Plastering: Why a Professional Finish Matters

Think a 'glass-smooth' finish is best? Think again. We explain why over-polishing causes paint to peel and why we strictly use the British Gypsum two-coat method for a durable result.

Introduction

Most people have a specific image in their head of the "ideal" plastered wall. They imagine a surface that shines like a mirror, polished to a glass-like finish. It looks impressive in photos, and to the untrained eye, it screams quality.

But here is the uncomfortable truth: A "glass-smooth" finish is actually a nightmare for your decorator.

There is a massive difference between a wall that is consistently flat and a wall that is over-polished. When a plasterer over-works the material to get that super-shiny, reflective look, they are effectively sealing the surface shut. They close the pores of the plaster entirely.

Why is this bad? Because paint needs something to grip. If the surface is sealed tight, your expensive emulsion paint will just sit on top rather than bonding with the wall. It becomes a struggle to get good coverage, and in the worst cases, the paint can peel or flake off months later because it never truly adhered.

The Abode Standard: Flat and Matte

At Abode Plastering, we don’t aim for glass; we aim for Flat and Matte.

A professional finish should be consistently flat and smooth to the touch, but with a matte texture that provides just enough "tooth" or suction. This ensures your paint bonds correctly, the colour looks deep and consistent, and the finish lasts for years.

The Process – Why We Use the Two-Coat Method

One of the biggest shocks for a beginner is discovering that plaster doesn't just "dry" like paint—it "sets" chemically. Once the water hits that powder, a countdown clock begins that you cannot stop.

At Abode Plastering, we strictly adhere to the British Gypsum two-coat skim method. Many DIYers (and even some rushed tradesmen) try to get away with a single thick coat to save time. This often leads to uneven drying, "slumping," and a poor finish.

We do it properly:

The First Coat: We apply the initial layer to create a flat, consistent base. We then flatten this down before it sets.
The Second Coat: Before the first coat is fully hard, we apply a second, tighter coat to fill in any minor hollows and create a dense, uniform surface.
The Trowelling Up: This is where the skill lies. We don't just rub it once; we work the plaster through specific stages of firmness to compact the surface.

It’s Not Just About the Trowel

A common misconception is that if you buy a plastering trowel, you can plaster a wall. But that is like saying if you buy a scalpel, you can perform surgery.

First, there is the equipment itself. You cannot achieve a professional flat finish with a cheap £10 trowel from a DIY store. At Abode Plastering, we use specialist tools from industry leaders like Nela and Refina. These are precision instruments designed to flatten walls without dragging or warping the surface.

Then, there is the "muscle memory." Plastering is physically demanding, but it requires a delicate touch. It’s about pressure control.

Too much pressure: You rip the surface or leave "tram lines."
Too little pressure: You leave "chatter marks" (ripples) or air bubbles.
Inconsistent angle: You end up with a wavy wall that looks terrible under artificial light.

The Abode Plastering Standard – Cleanliness is Part of the Job

There is an old stereotype that plasterers are messy. And sadly, with many tradespeople, it’s true. But at Abode Plastering, we believe that respecting your home is just as important as the finish on the walls.

We don’t just walk in and start mixing. We treat your property as if it were our own.

First Layer: We lay down heavy-duty, waterproof tarpaulins to secure the flooring.
Second Layer: We top this with dedicated absorbent cloth coverings to catch any fine dust or minor splashes.
