Thin-Joint: How to use the Tools
The H+H Thin-Joint System is designed for speed of build and air-tightness, but in order to achieve this you will need to use the correct tools and materials.
You will need:
- Celfix Mortar
Supplied as a dry, pre-mixed powder in 25kg bags, which is then mixed with 4.5 litres of water.
- Mortar whisk
Most commonly 100mm to 140mm diameter with 3 blades.
- Notched proprietary scoop or sledge
Celfix Mortar should be applied with a notched proprietaty scoop or sledge that is the correct width for the block you are using. For example, if you are building with 100mm Celcon Blocks Standard Grade, you will need to use a proprietary scoop or sledge that is 100mm wide.
- Bed joint reinforcement
Metal is recommended for all applications, though glass reinforced plastic is acceptable in some situations.
- Wall ties
Dependent on the type of build, there is a large number of wall ties to complement the Thin-Joint system from restraint ties to movement joint ties.
- Block and sanding rasps
Used to eliminate any imperfections in the block work that may occur during the construction process.
- Block saw with tungsten carbide teeth
One of the great benefits of using Celcon Blocks is that you can cut them on site. However, it is important to get your measurements correct because Celfix Mortar sets quickly; meaning mistakes are less easily corrected.
- Block cutting saw guide
Most commonly 200mm or 250mm in diameter.
Notched scoops may be supplied by H+H if a structural masonry package is purchased. Otherwise, I recommend tools from Tackburn Ltd. It provides a full range of scoops and sledges, hand tools and power tools to complement the Thin-Joint System.
