How to Joint a Patio or Paved Area
The video begins by showing the preparation needed before applying the jointing compound, which is a material used to fill the gaps between paving stones. This step is key for all newly laid or existing paved surfaces. It guarantees a strong bond and a lasting finish. The footage clearly shows the required joint gaps. These need to be four to six millimetres wide with a minimum depth of 25 millimetres to hold the compound. Workers are shown checking that the paved area is level, dry, and clean before installation. They use a stiff-bristled brush, a brush with firm, coarse bristles, to sweep out any loose soil, stones, or debris from the gaps. This is critical for a successful application.
The jointing compound comes ready-mixed and pre-packed. It is unsealed and poured directly onto the wet paved surface. The Geo-Fix Paving Jointing Compound (Buff and Grey) is shown spread across the area. A soft brush is used to work the material across the surface, pushing it into the gaps at a 45-degree angle. The process is shown in small working areas of about two to three square metres. Excess material is moved onto the next patio section. Once the bag is opened, use it fully. This prevents premature hardening and wasted material.
To finish and guarantee strong joints, the compound must be firmly compacted after the first application. The footage shows a pointing tool pushing the material fully into the joints. This consolidates the bond for weather resistance. After this, any leftover material is brushed off before the compound sets. The finished area is then left to harden. Curing takes a few hours, depending on temperature and weather. This clear process creates pavement that resists weed and plant growth.
