Screed reinforcement mesh

Reinforcing mesh for floor screed is used to ensure the strength of the entire floor surface and serves to distribute the load. Reinforcement allows you to level the floor before laying the floor, giving it the necessary strength and resistance to various loads. The device of floors using a grid for reinforcing screeds eliminates the risk of cracking the base, maintains its shape during operation, not allowing it to collapse. In addition, reinforcement has a positive effect on the basic properties of the concrete coating.

The main types of reinforcing mesh

Screed is a transition layer that connects the main surface of the floor with the final coating. It is carried out not only for hardening, but also to ensure properties such as waterproofing, thermal insulation and soundproofing of the room. To reinforce the concrete surface, most often, two types of mesh under the screed are used:

• Metal;

• Plastic

The mesh under the screed is laid at a height of about three centimeters from the floor, after which it is poured with concrete mixture. Here you need to make sure that it does not touch the subfloor, remaining in the very thickness of concrete.

Reinforcement of the floor screed with a metal mesh ensures maximum strength of the base. This material is used for layer thickness pouring no more than 80 mm. It is best to use a metal mesh in rooms exposed to fairly high loads - an entrance hall, a kitchen or when organizing a floor heating system.

The metal mesh can be made of individual wire elements that are twisted together. It may also be a welded product.

Plastic structures for concrete floor reinforcement are made of modern material - polypropylene. Due to their excellent elasticity, they are widely used for reinforcing floor surfaces in new homes. After all, they undergo strong shrinkage, and the elastic mesh prevents splits and cracks. Plastic mesh for floor screed, unlike similar products from other materials, does not corrodes, has a long service life, low weight and is characterized ease of installation. In addition, it is able to withstand very strong loads, both in longitudinal and in cross section.

Modern way to arrange screeds

Reinforcement of floor screed can be carried out not only by laying the net. Dispersion reinforcement, which uses fiber from glass, steel or other materials, is gaining great popularity today. However, such a reinforced screed is not suitable for rooms with increased loads, and therefore in some cases it is used as an addition to the first method of hardening the floor. Fiber fiber provides the most rapid ripening of concrete and the manifestation of a property such as plasticity.

The use of fiber for concrete floor reinforcement is a new, modern method. It allows you to reduce concrete consumption during pouring and does not allow it to crack.

How to lay a grid?

• A metal mesh for durable reinforcement of the floor screed is laid on a concrete floor cleaned from dirt and dust. Thoroughly clean the base of debris, dirt and even stains of paint.
• In order for concrete to adhere to the rough surface in the best way, it is necessary to prime the base with a special composition.
• Metal or wood installation lighthouses along the upper border of the grid will provide you with an even bay.
• To soundproof the room you will need penofol, which must be attached to the wall.
• The mesh under the screed is laid, and the solution is poured into the resulting distance between the beacons, after which alignment is performed.
• As soon as the concrete dries a little, about thirty minutes after pouring, the surface needs to be wiped.
• Beacons are removed somewhere about seven days after the bay, and the voids are sealed with a solution.
• To prevent drying out of the surface and cracks, the screed should be regularly wetted with water.
• It will take a month for the concrete to dry completely.
• Maintain a constant temperature during work and drying of concrete at twenty degrees Celsius. Avoid drafts and try to lay in one day a grid for a coupler of a floor of one level.

Nets for floor screed make it possible to significantly reduce the thickness of the concrete layer and make it stronger, more stable. It is especially indispensable for organizing floors in wet rooms, as it is able to maintain their shape even when completely filled with water. To make the floor even more even and smooth, after drying the composition, make an additional layer, applying self-leveling mixture.
