We use SBR for every plastering job

In this article we cover why we tend to use SBR instead of PVA when plastering.

What happens when you use PVA and then paint?

PVA forms a silky layer that prevents paint from adhering to the wall. If you have sections of a wall that has been treated with PVA it can be very difficult to remove before painting the wall. It’s essential to remove the PVA by sanding and breaking down the sealing barrier before painting, as the paint will crack and flake off.

SBR

Whether it’s a modern statement wall or a timeless heritage look, we can bring your vision to life with our plastering service. We work on a variety of walls and treat each wall with SBR before plastering.

  • PVA is good and so is SBR. We just find it easier to use SBR as a go to for platering work. It’s easier to apply and comes ready mixed.
  • SBR is easy to roll on with a short pile roller and brush.
  • SBR provides good adhsesion and also helps to controll the suction.

How we use SBR before platering

Here’s how we deliver a professional plastering finish every time.

Step 1: Consultation and surface assessment

Good wallpapering starts with good preparation. We begin by discussing your vision to find out whether it’s bold geometrics, subtle textures, or classic florals. Then we assess your walls for imperfections such as moisture issues, or peeling wallpaper that need removal. Our wall assessment ensures that we get the correct paper and application for lasting wallpaper that looks great.

Step 2: Wall preparation

Before we can apply your new wallpaper, we will remove old wallpaper or loose paint. Where walls have cracks uneven surfaces we will fill cracks or even quote for plastering where required. Once the walls have been prepared we apply primer or lining paper in some cases. After ensuring that the walls are clean, dry, and dust-free we will apply wallpaper adhesive to the wall or paper depending on your option and required coverage. Our wall preparation provides a smooth sruface that provides lasting wallpaper.

Step 3: Measuring and cutting

We measure your walls precisely cut each strip with care. It’s often better to start in the middle of a wall and work towards the corners. Our measuring accounts for pattern repeats and tricky areas like corners, sockets, or coving. By allowing for a neat and tidy line without gaps between the seams.

Step 4: Adhesive application

Depending on the wallpaper type we will (paste-the-wall or paste-the-paper), we use the correct adhesive and technique to avoid bubbling and peeling. It’s essential to get even coverage, allow for soaking time and make sure the wallpaper face and skirting are clean at all times.

Step 5: Hanging and smoothing

Each wallpaper strip is aligned and applied with precision before cutting along the ceiling and skirting boards. We use smoothing tools to eliminate air bubbles and ensure tight seams. Our prefered tool is to use a self-levelling laser to indicate (green laser lines) that the paper is correctly hung before smoothing to the wall. This helps us to match patterns perfectly.

Final step: Inspection and clean up

We inspect every detail, tidy the room, and leave your home ready to enjoy your newly decorated walls. You’ll provide some care tips to keep your wallpaper looking fresh for years.

Allow at least 7 to 10 days for skim or multi-finish plastered walls to fully dry. This allows the moisture to fully evaporate and the surface to cure fully before wallpapering. Don’t rush as wallpapering over plaster too soon will result in bubbles, peeling wallpaper.
