For a DIY plastering job, you’ll need to make sure that you have the right equipment and materials to ensure that the finished project looks good and has structural integrity. Suppose you have invested some time and resources into getting the right tools and materials, what are some tips to guide you through the process? Here are some helpful hints for novice plasterers undertaking a DIY project.
Don’t rely too much on your trowel
The purpose of your trowel is to help you apply plaster in the correct amount and thickness. A trowel is not meant to achieve a perfect and smooth finish. The straight edge is the tool that will eventually help you smooth out all the rough edges. However, note that the straight edge will not be able to do its job if the plaster is too thin. Ideally, you should apply plaster at least 5mm in thickness.
Before you apply plaster, you initially have to apply a layer of basecoat. Depending on the type of plastering project, you may or may not need to do so. In cases when you do have to apply a basecoat, roughly apply this to the entire area. You don’t need to work too much to smoothen it out. You can also use a straight edge for this. Before applying any type of render or Parex render over the basecoat, you need to allow it to set property first to avoid getting blisters.
Dealing with uneven surfaces
There are different kinds of rendering materials for use in most plastering jobs. For example, there are plastering materials such as Monorex GM and Monorex GF by Parex that are ideal for indoor walls. It is important to make sure that you are getting the right kind of materials suited for the job.
In case you encounter uneven surfaces, you need to pack and level the surface before you start skimming. If there are cracks, don’t forget to add scrim tape before packing in your preferred plaster material such as Parex Paraguard. To avoid the sagging effect when dealing with joints, place a small amount of plaster material into the spaceand push it into the joints. Repeat this process for all joints and spaces before starting the skimming process.
Rough or textured surfaces
The skimming technique is also helpful when dealing with rough or textured surfaces. But when the difference is more than 5mm, you may need to start with a basecoat instead of skimming with plaster. You can also use a bonding coat instead of a basecoat before proceeding with the skimming process.
These are only some of the pointers that can help you succeed in your DIY plastering project. Again, there are other techniques you can use depending on the surface and type of Parex supplies you are using. You can always research instructional videos and guides to help you through the process. It is important that you are using the right kind of material and applying it with the proper technique to guarantee good quality results.
