How to paint a room
Most rooms are already painted and usually have to be repainted because:
- The colour needs changing.
- The paint has become shabby and dirty.
- The paint may have started to flake.
This is 90% of the total job and is critical for obtaining a top quality durable finish. More work must be spent on preparation than actually painting. At least two thirds of the labour must go into surface preparation. It is the hardest part, but vital for good service life.
- glossy finishes including sheens: light abrasion with scotchbrite, water, using a quality de-greasing cleaner and etching fluid.. Dilute the cleaners according to manufacturer’s instructions. Wash & then rinse with clean water and leave to dry.
This is the safest method to prevent poor adhesion of the new paint.
Matt finishes: wash well and rinse with clean water. Leave to dry.
Flaky paint must be removed using a scraper blade or spatula. Mechanical methods such as a power wire brush tool also helps, but be careful…. The underlying surface can be easily damaged this way!
Flaking usually occurs because there is a weak coating underneath the paint film. This is usually due to gypsum filler or skim coatings. This material is too weak to be a good surface for painting. Sealing it with bonding liquid such as Fired Earth Bonding Liquid certainly helps; but if at all possible, please do not use.
Once all flaking paint has been removed, seal any exposed plaster using Fired Earth Bonding Liquid, leave to dry for 2-3 hours then skim the affected areas with a quality ready-for-use acrylic filler compound. Leave to dry for at least 6-8 hours to ensure good curing before continuing.
Which paints to use:
There are several options here:
Matt finishes hide minor surface blemishes and are useful for uneven walls.
Silk/sheen, semi-gloss and glossy finishes generally have better washability, but highlight any uneven blemishes in the wall or ceiling.
These coatings should be over coated with top quality acrylics. Silk/Sheen coatings highlight the ripple effect. The ripple paints must be applied with the correct roller: an open-celled polyurethane foam roller.

Some very important tips for painting indoors:
1. Make sure you have good ventilation.
- This is good for the paint to dry properly.
- This is important for the paint applicator.
2. Always allow the paint to dry properly before re-coating.
- Acrylics: allow 2 hours minimum.
- Enamels: leave to dry overnight.
3. Make sure the roller; brushes etc. are clean and in good condition before starting.
4. Do not underestimate the importance of surface preparation: it is 90% of the job.
5. When applying paint, always make sure that the paint is applied in a uniform manner: thick and thin films result in sheen or gloss variations and can make the paint coating look like it is striped!
6. When using a roller…
- Use the correct one (mohair for enamels; wool or synthetic type for acrylics).
- Always use a roller tray and ensure that the roller is evenly coated with paint before applying it to the wall.
- Recharge the roller for each strip of paint applied: start each new strip from a different end from the previous (e.g. start at bottom, next strip start from top etc,). Apply 4 strips then spread the paint horizontally before laying off with a light stroke from bottom to top.
- Poor technique will spoil the job.
Painting Bathrooms (and Kitchens)
- These areas are subject to a lot of water and humidity. Fired Earth Non Drip Enamel is highly recommended due to its extra toughness and water resistance.
- The tips already mentioned for painting rooms apply for bathrooms and kitchens as well.
