How To Sand Trim Before Painting?

The term “painting” is pretty self-explanatory. Putting paint on anything can be considered as painting. But the color needs to stay, or else you will have to repaint your interior repeatedly.

If you want your paint to last a more extended period, you will need to sand the trim before painting. In this segment, we have broadly discussed this topic.

The most important thing to remember here is that your paint will stick depending on how well you have prepared the wall before painting.

So do not be a lazy lad and take this seriously because this little work can save a lot of work in the future.

These are the five steps of How to sand the trim before painting.

First step: Sanding

The first step is sanding.

Sanding is just for removing the shine of the wood. To be more precise, you need to sand to remove the smoothness and provide a surface that can hold the paint.

The sanding does not need to be too much. You need to make sure that the body is rough enough for the paint to stick.

Second step: Using caulk to fill the gaps

Use caulk in trim to fill the gaps

The second step is closing the gap with the help of caulk.

A step that most professionals follow and non-professionals do not. Before that, we told you that you could do a near-professional work by yourself if you have the proper knowledge. This step will give your task a professional look.

Take some caulk and put it in between the gaps of your trims. Caulk will fill the gap giving it a smooth finish.

Third step: Cleaning away all the dust

The third step is cleaning.

Take a cloth and wash away all the dust using some spirits. If you have a dusty surface, the paint will not be long-lasting because your color will sit on the dust and not the body.

So when there is wind or something like that, the paint will fly away along with such things.

Fourth step: Adding a layer of primer

The fourth step is providing a primer coating.

A primer helps to prevent any leakage of paint and make it look more presentable.

Use a decent brush that will cover all the areas adequately and leave no blank spaces. Generally, one layer of primer is enough, but if you notice any colour leakage, add another primer layer to ensure no further spread.

Fifth step: Paint and finalize

Here’s the final one.

Take a good brush and paint the trim that you want. Paint it carefully to make sure there are no gaps. Add two or even a third layer of paint to make sure the quality.

The best way for painting is to use a spray. But a spray can be hard to work with, as you can not dictate the way it moves.

Only use it if you are confident enough in your abilities; otherwise, stick to using a painting brush.
