How to use a Laser Level?

A laser level is a construction tool. It’s a modern tool that uses line laser modules for many application, such as measuring the width of the room.

Steve Orosz invented light beam leveling technology in 1996 for acardiac monitoring application (U.S. Patent 5836081). Engineers and Scientists have explored how to apply the technology to different fields, such as how to use a laser level. The result was found that this is used in large construction and civil engineering sectors the most.

A laser level is a modern tool that uses line laser modules for many application, such as measure the width of the room. Also, laser levels could be used to make sure that whether the measured object is leveled and plan from the roof or from the floor.

In the past, people used to take a lot of steps to mark several points on the wall from floor to the top and take the measurement several times to guarantee the accuracy of the result. But by using a laser level, it is very easy and simple.


How to use a Laser Level?

To use a laser level, first of all, you need to set the laser in a place maybe in the center of a room. Then switch on the laser which is a straight horizontal or vertical line directed onto the wall. The height of the laser line is adjustable as well.

The laser line is always horizontal or vertical. Also, you can do the measurement and settlement with a free hand. It is very useful in the settlement of the furniture. There are some situations when you need to set some cabinets at the top of the kitchen or in the room. For this application, you can use a laser level.

When you are in a room, take a look at the whole house. If there are any places that you think you need to change or plumb, you could do it by yourself with the help of the laser level. It is an easy operation. And to fix the house, it would become an easy and time-saving job for you.

In many other projects, laser level could also be used. The traditional leveling work will cost a lot of human resources, time and money. By using this one, it would save your money and human resources at the same time. Also, the accuracy of the work could be upgraded. And there is no special need to maintain the laser levels.



Different Sorts of Laser Levels with the Usage

You still might be wondering for what purposes you are going to use a laser level? Do you intend to work only indoors, only outdoors, or both? These are the question that will define the features you will want to look for and buy.


Indoor Application of Laser Levels

♦ Align and plumb your walls

♦ Leveling floors

♦ Easily check door or window heights

♦ Installing  drop ceilings

♦ Install chair rails and wainscoting in your home

♦ Align shelves, Cabinets, and trim

♦ Any type of basic surveys

♦ Lasers easily check and level posts and beams on decks land elevation

♦ Masonry alignment

♦ Site layout

♦ Easily check land elevations

♦ Lasers with a slope capability can set grade for proper drainage and irrigation

♦ Align fences, posts, and decks

♦ Establishing grades

♦ Contour framing or drainage

Now it’s time to discuss different kinds of laser levels that are available in the market.

Automatic Rotation or Rotary Laser Levels

A rotary laser line of light is projected with the use of a laser and the use of mirrors. And the colors of laser lights used mostly are red or green.

If you have a line drawn on the wall with the laser with a uniform level, this would be definitely helpful when you need to get a precise level across the whole room. This is great for skirting, dado rails, leveling, windows, doors and other openings- there is no shortage of uses! To set up a laser level on a tripod you need to erect the tripod first. Most modern tripods come with a leveling bubble built in and individually with adjustable legs.

This process will be repeated on the laser leveling device once it is positioned on the tripod. More expensive models of the laser level will come with a fully automated leveling system.  These levels are used when an accuracy is required. It is advisable to buy or use a device with a built-in self-leveling action.

The most common use of a Rotary Laser Level is to find a set of constant height around a room for a vertical measurement to be taken from the illuminated laser line for the use of constructing level floor surface or suspended ceilings.  specific spots can be created on wall surfaces or other particular points while the laser is projecting.

Automatic Rotation Laser Levels can be expensive, and they are a little more complex to set up, but they can save a huge amount of time and ensure your success for your projects.


Optical Levels

An Optical Level surveying tool which you look through ( once leveled) to mark a level on a batten or “ staff” as it’s called. The staff is then moved to another part of the site and when the level is trained on the staff in its new position.

You can then compare the point B and point A and how low or high they are from each other. These are tools that are less likely to be used by the DIY but more likely to be useful for the self-builder. On the whole, when you employ a professional surveyor as this is a skilled job and require a great deal of accuracy, this might help.


Horizontal Lasers

A horizontal laser will only emit a single beam from its beacon.


self-Leveling and Automatic-Leveling Lasers

A self-leveling laser automatically finds and maintains a level within a specified range.



How to use this tool for installing tiles on the floor?

When installing tiles on the floor, you have to take care of one important aspect and that is, the right alignment and placement of tiles.

In a specific corner, place the tile laser level or laser square or square laser level and switch it on. Through the laser lines, you can make the positioning of tiles between zero to ninety degree. With a notched trowel,  spread the mortar evenly over a small area. Then, following the line of level, place the ceramic tiles over the mortar and press it in the required place.

Place another tile next to the first one. Use plastic spacers to keep the joints of the tiles uniform. Repeat the process again and again. Always keep the alignment in mind before laying the tiles.


Mount Laser Level on a Tripod

Most laser levels have a threaded hole on the bottom that accepts a standard ¼ in tripod mount. Some laser levels come with a tripod. But if yours doesn’t, it’s worth buying one. A tripod allows you to easily adjust the laser to the best height and levels it on uneven ground.

But you don’t need a tripod that’s designed for lasers. If you already have a camera tripod,  it all probably work just fine with your laser since the threads are usually the same size. Or buy a cheap one wherever cameras are sold.


Final Words

Since the laser is harmful to human being’s eyes. It is much better to wear the safety glasses when you do the jobs. Safety glasses could protect you from being harmed by the laser. In sunlight, the laser is not clear, so it is better to wear the safety glass.

I’ve tried to give clear ideas on the types of laser levels and how to use them properly on different aspects. Hope this article has helped you get through the instructions on how to use a laser level.
