Break a partition: how to do it?

Breaking a partition is not decided on a whim! Before embarking, a little theoretical and practical preparation is required. Without forgetting to think about the after ...

In a trend of large spaces, tearing down a partition is often tempting. However, breaking a partition is not trivial and requires a little preparation. Finding out about the quality of the wall (whether or not the wall is on it), checking whether there are electrical or plumbing networks are key steps for the theoretical part. On the practical side, protecting the rooms, properly equipping oneself or anticipating a possible catch-up on the floor and on the ceiling are important points for breaking a partition. With the help of Olivier Martinache, Material Product Manager for Leroy Merlin, and Philippe Carillo, the creator of the Interior Designers collective, discover all the information you need to take down a partition at home safely.

1. How to recognize a simple partition of a load-bearing wall?

Break a simple partition or a load-bearing wall do not require the same technique. A partition is easy enough to cut down while the load-bearing wall requires much more preparation. The initial step is to know how to differentiate them. "The first instinct is to look at the thickness of the wall," advises Philippe Carillo of the "Interior Designers" collective, "The finer the wall is, the more likely it is to be a simple partition." Another tip, more technical, knock on the wall to estimate its material. "A plasterboard partition rings hollow and can not be structural and therefore non-load bearing," says Olivier Martinache, product manager for Leroy Merlin.

Even if a partition is not a carrier, in older homes, it can become so over time, especially if the beams are weakened. To ensure that you do not cut down a wall by mistake, it is best to check the house plan or to call in a professional (contractor, architect or concrete engineer) to be well informed.

2. How to know if the partition is empty of all networks?

Another crucial step before breaking a wall is to check if the wall does not hide an electrical or plumbing network, which involves reviewing the entire circuit before cutting the wall. This is primarily a matter of common sense. "If there is a switch, a radiator, electrical wire outlets or a tap, a water supply, there must be an electrical network or plumbing in the partition," says Philippe Carillo. When in doubt, refer to the plan of the dwelling, a safe bet to avoid big problems. "There are also detectors that can be used to check the presence of metal networks," says Olivier Martinache.

3. What are the steps to break a partition?

Once the theoretical verifications are made, place to practice! Beforehand, start by preparing your site and your protection to break a partition. "It's important to dress well with a suit, a mask and protect the floor," says Philippe Carillo. Once the site is ready, do not forget to cut the water, electricity and gas networks. "Arm yourself with courage, a hammer and a chisel to destructure the solid, a saw for plasterboard tiles or an electric saber saw for aerated concrete, recommends Olivier Martinache.The tools vary depending on the composition from the wall." Break the partition starting with the high parts and going down gradually, although we can not wait to see the result. Finally, remember to take rubbish bags, very useful once the site is completed.

4. Can we break a load-bearing wall?

"Any wall is demolishable!" Reassures Philippe Carillo. But the steps are not the same as breaking a wall. Philippe Carillo continues: "You must call on a DPLG architect or a concrete engineer to validate your project.The wall must have been sounded, without risk of weakening the building." Note that a wall can not be broken without agreement of the condo if you live in a collective housing. "Validation is necessary on the part of co-owners to break a wall in an apartment, said Philippe Carillo, they must validate a plan approved by a professional." On the practical side, IPNs (support beams) are needed to reinforce the building.

5. How to make a catch on the floor and ceiling?

Once the partition is removed, there is a good chance that a catch-up is to be made on the floor and ceiling, unless the wall is placed on the floor covering. "In 80% of cases, there is a catch-up to do, warns Philippe Carillo Leave a piece of the partition can often avoid having a smoothing to do." In order to create continuity on the floor or ceiling, some small decorative work is required. "The retrofit requires the installation of a threshold bar a little wide (100 mm minimum) to ensure the link between the two parts to join, advises Olivier Martinache.On the ceiling, a little coating and paint allow catch up. " And if instead of hiding this defect, you play it? Philippe Carillo offers several ideas: "We can also make a style effect if there are two different floors, for example, and have fun with a wooden blade, concrete or a line of color on the floor or ceiling for a very graphic effect.
