When it comes to laying concrete, there are many factors to consider to ensure a successful outcome. One of the most important factors is the use of a concrete bond breaker. This article will cover everything you need to know about concrete bond breakers and how to use them properly on your next concrete project.
A concrete bond breaker is a substance used to prevent adhesion between two surfaces. In the context of concrete, a bond breaker is applied to the bottom of a concrete slab to prevent it from bonding to the base material beneath.
The main reason to use a concrete bond breaker is to allow for movement of the concrete slab without causing cracking. Concrete expands and contracts with changes in temperature, and if it is bonded to the underlying base material, this movement can cause cracking in the concrete.
Another reason to use a bond breaker is to facilitate the removal of the concrete slab if necessary. If the slab is bonded to the base material, it can be difficult and time-consuming to remove.
There are several types of concrete bond breakers available on the market. The most common types include:
Chemical bond breakers are liquids that are applied to the surface of the base material in the form of a spray or roller. Once applied, the liquid dries and leaves a thin layer of film on the base material surface, which prevents the concrete slab from bonding to it.
Tape bond breakers are adhesive tapes that are applied to the base material prior to placing the concrete slab. The tape prevents bonding between the two surfaces and is removed after the concrete has cured.
Mat bond breakers are made from a non-stick material and are placed between the concrete slab and the base material before pouring the concrete. The mat prevents bonding between the two surfaces and is removed after the concrete has cured.
The process for using a concrete bond breaker depends on the type of bond breaker being used. In general, the following steps should be followed:
Using a concrete bond breaker is an important step in ensuring the success of your concrete project. With the information provided in this article, you should be able to choose the right type of bond breaker and use it properly to prevent cracking and facilitate the removal of the concrete if necessary.
