How to Plaster Home Walls This Christmas – A Quick Guide!

Ever thought what happens to your walls before you paint it or put up your flowery wallpapers? You gusseted it right, plastering. It is the process of covering rough and exposed surfaces with plaster; a combination of lime or cement concrete and sand. This is done to protect the surface against rain water and just makes it look better. It is usually done before decorating the wall with paint or wallpaper.

  1. Get everything ready

Get all your equipment ready first. You would want to cover the floor with dust sheet in case some of the plaster falls down. Further, if there are any holes, gaps or cracks in the wall, make sure you cover it up before applying the plaster. You may also want to keep a bucket of fresh water ready before you begin.

  1. Use PVA on the wall

Applying PVA (Polyvinyl Acetate) before the plaster makes sure that the plaster will dry out evenly. You need to dilute the PVA before applying. The ideal PVA to water ratio is said to be around 1:4. Cover the entire wall with PVA and then start with the plaster right away.

  1. Mix and apply the first coat

One thing to remember is to mix the plaster into the water, and not vice versa. The water must also be cold. Keep mixing the two until you get a smooth mix without any lumps. A strong mixer may be used for the same as the plaster may be thick. The plaster will come with instructions you can follow to avoid anything from going wrong.

Next, use your hawk to collect the plaster and then a float to firmly spread it onto the wall. It is a thick mixture, so you will need a bit of a force. It might not be as easy as it looks so you will take a while to get used to it.

  1. Smoothen it out and scrap if required

Have your plaster dry out a little before this step. Use a trowel to smoothen out the plaster now. Get rid of all the unevenness and extreme bumps. Target the corners and edges as well. Scraping the wall is optional and can be done before applying the second coat.

  1. Apply the second coat

Now comes the second coat. Before you do so, dilute the plaster further as this coat needs to be thinner than the first. And then leave it to dry on its own.

  1. Polish your work

After the second coat has dried slightly, you may begin your finishing touches. Apply water to the surface and then use a trowel to flatten out the unevenness. Sand paper comes in handy after the plaster has dried completely to take out the excess parts. It is important to give the plaster a fine finish.

  1. Paint your wall

Finally, the plaster is ready to be painted over. It is recommended that you seal the surface before doing so. You may use one or two coats of adhesive to prime and seal the surface.
