How to Use a Laser Level

How to Use a Laser Level

A laser level is a key piece of equipment used in measuring and levelling jobs. They automatically project a straight, even 360-degree line onto your walls, floors, and other solid surfaces, which can be horizontal or vertical.

They’re commonly used for construction and building work. But you may also need to use one if you’re doing some home improvement, such as fitting panelling and need to ensure every panel is in line and straight, or if you’re creating a feature wall and want every picture frame to be in line.

They can also be used to fit dado rails, install kitchen cabinets, or level a concrete or patio floor which is uneven or contains dips.

Using a laser level is much easier than a tape measure or spirit level, as they are freestanding and can project a level line with no additional work from you. You also don’t need to use a level or plumb, as the laser beam does the job for you.

They can be used on a tripod if you need some additional height and are often controlled by just one or two buttons. Most tripods are usually adjustable in height, too.

When using a laser level, follow the instructions specific to your model. In general, the guidance is the same. Below is a guide on how to use a laser level.

Using a Laser Level

Laser levels can give off quite bright lights, so ensure you’re wearing protective eyeglasses and avoid looking straight at the source of the light.

Before carrying out your DIY job, ensure you wear the correct PPE required, which can be purchased from Speedy.

1. Position the laser level

It is a good idea to put the laser level in the centre of the room. This way, the laser can go right round the room.

If you’re using a tripod, ensure the tripod is even using the built-in levelling bubble. The legs of the tripod are usually adjustable, so you can even use the laser level on an uneven floor if you don’t have a flat surface.

2. Calibrate the laser level

You can calibrate the laser level by making sure the bubble is aligned in the vial. This is usually done by adjusting small screws until the bubble is in place.

A self-levelling laser will do this itself if you give it time.

3. Make the necessary measurements

Once the laser level is turned on and showing the light, you’re free to do the work required.

This could be fitting screws, hooks, or dado rails around a room, or fitting panelling in a straight line. You can also spot any uneven sections on a wall or detect dips in the flooring for levelling a floor.

Determine your desired height for the job and adjust the laser so it lines up. If levelling a floor, determine the desired height until you have enough reference points to fill the area completely.

If using the laser level outdoors

If you are using the laser levels outdoors, it may make it more difficult to see the lines or lasers in brighter light or direct sunlight.

You can use reflective material to mark slight increments of the level, such as a metal ruler or even tin foil.

Wear sunglasses and use the Daylight mode if your model has it; this will give you a dimmer, often pulsing light which is easier to see.

Some laser levels also allow you to choose between a red or green light. A green laser level beam is often easier to see in high light, as it is up to 50x brighter than red lasers.

You can also use a laser detector, which pulses when it comes into contact with the laser, although this will come at an additional cost.
