How thin can you pour a concrete overlay?

In these cases, I would use fine sand mixed with Portland cement. The typical thickness acceptable to many contractors is between ¼ and 2 inches thick. Technically, concrete overlays can be as thin or as thick as desired. However, the best thickness to work with may depend on the type of overlap you choose to work with.

The polished concrete coating is poured on site. The recommended floor area between expansion joints ranges from 6000 to 7000 mm maximum. The angles of the expansion joints are approximately. Consult your Covet concrete coating specialist to discuss your project requirements.

The minimum thickness for pouring concrete onto concrete is 1.5 inches. In most cases, I don't like pouring new concrete less than 2 inches thick. For concrete floors that require repair, a layer of concrete means tackling repairs to the substrate and covering it with a cement-based layer that does the following;. The beauty of a concrete coating system like X-Bond is that you can still achieve a concrete-looking aesthetic on your floor, a finish that is more uniform, consistent, and can have the right shade of gray you expected.

Serious structural problems in the original slab will eventually affect the new concrete layer as well, and you will need to replace the new concrete along with the old one. Covet polished concrete cover is a super hard concrete surface installed on a solid concrete substrate. The coating material can be a simple mixture of sand and cement or, in fact, it can be a real concrete mix that includes small pieces of stone or even large stones, depending on the thickness of the coating. When thinking about making a concrete screed, you need to understand that its durability and the appearance of cracks depend solely on whether you performed the repairs of the concrete floor correctly.

There are many things that could have gone wrong that likely caused the concrete wear surface to fail, but the good news is that there is a repair method that will produce beautiful, long-lasting results. When you pour your new concrete onto Weld Crete, it activates it and binds the new concrete to the old one. On the contrary, if all repairs and corrective problems in the substrate are properly addressed, the concrete layer will not crack for many years. If you have a concrete floor or wall that looks drab and needs repair, concrete screed could be the solution that will solve your problems.

The most common reason for concrete fragmentation is that water was sprayed onto the concrete during the finishing process. I have personally poured hundreds of new concrete floors, slabs and patios, onto existing concrete that was rough, cracked, pitted, or with an incorrect slope. This involves pumping concrete into the cracks and under those sunken areas of a slab to level the surface.
