The Thin-joint System is widely used across the UK and is the preferred method of building in much of Europe. It is designed for speed of build and air-tightness, whilst reducing cost, build time and waste on site. So, it is no surprise that knowing how to use this modern method of construction is a valuable skill to have.
Here are my top tips to get you on your way:
- -
- Use the correct tools
-In order to achieve the best results using the Thin-Joint System you need to use the correct tools. In doing so, you can prevent any irregularities or imperfections should they occur. - - Mix Thin-Joint mortar correctly
-Celfix Mortar should be added to water in a clean bucket; full guidance is given on the bag. Mix using a power tool with a whisk attachment, set at a low speed, to achieve the thick smooth consistency required for the Thin-Joint System. Celfix Mortar should be applied using a scoop, or a sledge for solid walls, to suit the block thickness in order to provide a consistent 2mm joint thickness. - - Concentrate on your cutting
-There are a number of ways that H+H aircrete blocks can be cut. The traditional method is to use a hand saw. However, depending on the size of the project and particularly when cutting larger blocks, more efficiency can be gained by using mechanical tools such as reciprocating hand saws, circular and band saws. Mechanical saws are particularly useful when there is a need to cut several blocks so as to achieve floor or plate height. - - Tidy up
-Make sure you tidy the back of the wall taking away excess mortar. If there are any holes in the joint, fill with the mortar to ensure the wall is nice and tidy on both sides. - - Practice
-If you have never used the Thin-Joint System, or you are beginning to learn, my advice would be to stick with it. The system has many benefits and learning how to use it is a great skill to have.
