5 Top Tips for Painting New Plaster
So, you decide you need a little makeover for your home. You think a great way of going about it would be to repaint your walls. You have plaster meticulously applied over your walls to make them smooth and flat. Now what? Confused about the best way to paint over the plaster? Well, you are in luck. Today we discuss 6 top tips for painting new plaster. These tips will help you avoid common DIY mistakes and ensure your paint job goes perfectly!
Tip #1: Be patient
Before you proceed with painting, you need to make sure that your plaster coat is dry. That is important for ensuring a good paint finish. If there are no dark patches on your plaster coat, it means that it has completely dried. You will see the new plaster change to a deep brown colour a few hours after it is applied, it will stay this colour for two days before patches start to change to a light pink. When the whole area is light pink – it’s ready.
The waiting time depends on your wall material, the weather and the ventilation in the space.
Generally, it is recommended that you wait a week before painting. If you want the drying process to move along faster, make sure the room is well ventilated but not too hot which can cause the plaster to shrink and crack.
Tip #2: Seal it
After drying, it is important to ensure that the paint adheres well to the wall. You don’t want too much paint to get absorbed by the dry plaster too quickly. One of the more common ways to help get a nice paint finish is to seal the plaster with a ‘mist coat’. This is basically a watered-down emulsion.
You can use a cheap white emulsion and water it down 2-1 and apply a light coat to seal the plaster.
Tip #3: Deal with problem walls
These days most of the walls in a home are made out of plasterboard which is a breeze to paint over. If your walls are made out of the more traditional lath and plaster, then you may have problems with cracking over time. Areas of plaster appear to have hairline cracks which may show through the paint. To rectify this, use an all-in-one basecoat emulsion. It will fill in the cracks and also seal the plaster.
Tip #4: Get to the root of the problem
Sometimes, the moisture will not go away no matter how long you wait for the plaster to dry. If you have walls made out of bricks, then there may be a deeper problem. Often brick walls get damp and hold moisture for a long time. Wall paper can hide this so you may not notice prior to having new plaster. Check for signs of a problem outside of the property like a leak in your guttering or foliage growing against the wall and holding moisture. Alternatively you may need to consult a damp proofing specialist.
Tip #5: Take care of the tray
Once you’re done painting, make sure you wash the tray completely. Do not let the paint dry in the tray, or it will contaminate the fresh batch that you pour in it. Alternatively, you can make a tray liner out of aluminum foil and just toss it away when you are done.
