How to Screed an Uneven Floor with Belzona 4131

This video demonstrates how Belzona 4131 (Magma Screed) can be used to quickly and easily restore the damaged top layer of uneven concrete floors.

The Problem:
Impact, wear and chemical attack – these are just some of the reasons why concrete floors deteriorate. The surface takes the brunt of these damage mechanisms, resulting in chipping and cracks that create an uneven floor and accentuate any problems further.

Of course, a like-for-like concrete screed repair can be the first option for many, being both a cheap material and readily available. However, this serves only as a temporary barrier for the aforementioned issues – one that they can easily overcome, returning the floor back to its damaged state and negating the “cheap and easy” maintenance method.

The Solution:
In comparison, polymeric mortar repair materials are a proven alternative for screed applications on to an uneven floor. Not only is their ease of use and excellent adhesion an advantage, but additional benefits in the form of chemical, impact and abrasion resistance combat the root of these issues. 

How-to Guide:
Step 1: Prepare the surface  using a grinder and remove any loose debris and dust.

Step 2: Mix and apply Belzona 4911 (Magma TX Conditioner) to the repair area with a stiff bristled brush in a thin layer.

Step 3: Mix and apply Belzona 4131 (Magma Screed) with a steel trowel. The minimum thickness for Belzona 4131 is ¼ inch/6mm, and the maximum thickness is 2 inches/50mm.

Step 4: Level the screed to the desired height.
