Plastering a wall can be a very rewarding experience when completed properly. There is much more to plastering a wall than you would expect. If done improperly, even the best looking results can be made to look amateurish and poor. Luckily for us, there are many people out there that have worked with plastering walls before and have written about their experiences online for other people to follow in their footsteps.

The techniques below were taken verbatim from various sources found on the internet and combined into one source for easier reading and understanding by myself, as well as anyone else who needs help with how to properly plaster a wall. I do not claim ownership of these techniques or any credit towards them – they were put together simply so no one has to search the web for hours trying to piece together all of this info on their own.

The following 4 steps are very general guidelines that can be followed in order or individually for any plastering task. The best way to learn is through repetition so it’s good if you have some spare time and/or money to practise these techniques yourself until they become second nature to you. I would recommend practising the proper technique on a few old sheets of drywall before moving onto real material. Plaster can be unforgiving when handled improperly, so there isn’t much room for error when applying it right the first time around.

Step 1: Prep Work

Before you get started, always make sure that there’s no furniture or anything else nearby that you don’t want getting dusty or damaged from plastering materials such as broken glass and little rocks (especially in outdoor projects).

Make sure to use drop cloths or plastic sheeting to cover up all nearby surfaces which might come into contact with any of the plastering materials down the road. Check every few hours for any leaks and fix them immediately if necessary since these particles could settle anywhere they’ve been allowed to just before finishing. This should include any other work you’ve done in the area recently.

Step 2: Rough Scraping

After ensuring that everything is covered, begin rough scraping off old plaster using a wide blade utility knife or paint scraper until it’s relatively smooth but still has some texture – don’t worry about completely removing all of the texture yet since it helps to give your plaster something extra to grab onto. If there are any loose areas it’s best to cut them out rather than trying to scrap them off since this will cause much less dust in your home or workspace when cutting into it with a blade.

Step 3: The Coats  

Once you’ve got everything roughed up, test out several different types of plaster mixes to find the perfect coverage when applied. For this step, just add water according to the instructions on the back or side of the package and stir well – these usually require 1 part powder mix to 2 parts water although experiment with anywhere between 1-3 parts water depending on how thick you’d like your coats to be.      

For even better results consider using additives such as latex paint (which helps the material stick to the wall better and shrinks less), plaster fortifier (helps to harden it and prevents cracking) or mesh (which you can use for finer textures such as smooth stucco).

You should always apply about 3 coats of plaster evenly in order to get a nice, even coat with no thin spots that might crack later on if too much stress is put on them. You don’t want any single spot to be thicker than another since this weakens the overall structure which could cause it to break off under pressure later on when people walk around above it.  

Step 4: The Final Coat    

After allowing each layer to dry overnight, add one last thin coat throughout the entire surface until you’ve achieved a nice smooth look to the wall. To get a really nice finished product, sand off any rough areas after drying and add a little texture if desired. For example, you could use a sponge for a rough stucco effect or even create an interesting design on your wall with tape before adding plaster.   

To keep your coat from cracking later down the road you should always avoid using pipes for anything run through the walls – these put too much pressure on them when weight is applied which causes them to weaken and eventually break off in chunks over time.
