Painting Venetian Plaster

By Mike Cupit


Venetian plaster is becoming more and more popular with many different styles and colours available. The issue is venetian plaster is pre-finished, so if it becomes damaged for whatever reason, you often end up having to plaster whole walls again.

This can cost a fortune and is not always practical. Painting your venetian plaster walls is a much more cost-effective way of doing things and can look stunning. You’ll certainly get them looking like new again. Not just that, but you can even change the colour if you’d prefer something different.


The Paint


What you must remember is Venetian plaster often contains lime which is alkali. Normal vinyl or polymer-based paint simply won’t stand up to it. There are a couple of solutions! You should really contact the manufacturer of the Venetian plaster to see which products they recommend, but the paint I stand by is called MATHYS Paracem Deco Ultra Clean Extra Matt. This is a specialist emulsion paint designed to withstand alkali and allow the surface of your wall to breathe.


You’ll find it easy to apply, opacity and spread rates are good and the overall finish is fantastic. It is also available in white, black or any British Standard colour. You can buy this product online, or from the Paint Shack by calling 01276 582321 .


A Recent Project


I thought I’d take you through a job I completed recently using the Ultra Clean Matt, just so you can see the impact you can have by painting Venetian plaster. The pictures below are of  a bar area with two different types of Venetian plaster on the walls. The plaster wasn’t too bad to be fair, but there was a couple of small repairs to do and to be honest, the whole lot had started to look a little bit tired.


The grey needed to be painted, however the smoother white plaster was fine. So the first thing I did was take mask white stuff off using frog tape This helped me to achieve nice crisp lines.


I then did the repairs using normal Easi-Fill and gave all the grey plaster a dust off. After that, it was simply a case of applying two full coats of Ultra Clean Matt in the specified colour. I diluted the paint slightly to make it easier to apply to the textured wall.


The job looked fantastic, it was inexpensive, and my client was chuffed to bits. We were in and out in two days, but this included painting the ceiling and all the wooden trim work.


I have included a few photos taken with my phone, however they don’t do it justice.
