Below are some ideas on the DIY projects you can do with an Oscillating Multi-tool.

1 - Trimming Door Casings With Oscillating Multi-Tool

Do you want to trim the bottom ends of your jambs and door casings to fit them properly with your new floor installation?

If yes, an oscillating multi-tool is an ideal tool to handle this kind of job without the help of a repairman.

All you need to do is to attach a flush-cutting wood blade to your oscillating tool, place a piece of your new flooring on the subfloor very close to the door casing and turn it upside down.

This will help to prevent scratching the good side of the flooring while helping you to determine the height to which you need to cut.

Now, hold the tool firmly with its blade flat against the piece of flooring you placed on the ground and cut directly into the door casing and then from one end to the other.

Your new flooring should now slide under the door casing soon after you trim and remove the severed piece of wood.

2 - Removing Old Paint With Oscillating Multi-Tool

No doubt, painting is one of the best home improvement projects to embark on using a DIY approach. It can yield a good visual improvement if it is carried out properly.

But when it comes to painting any surface, old, worn, loose and blistered paints can mar the quality of the task.

They, therefore, have to be removed before spraying or applying a new coat of paint to get the best result.

Removing old, worn, peeling or blistered paint on a surface can be very demanding, but it’s a lot easier with an oscillating tool.

To do this, fix the steel scraper blade to your oscillating tool to scrape off the loose, peeling and blistering paint.

Then change your tool accessory to a sanding pad and sand the surface down to the shiny metal underneath or to expose the wood.

You can start your sanding activity by using coarse-grit sandpaper and gradually progress to finer abrasives until you attain the degree of smoothness that you wanted.

Oscillating tools are equipped with one of the most useful attachments that are specially made for removing cracked, stained or old tile grout.
