Mortar plates grouted correctly and how it is done

If you want to lay sidewalk tiles in the garden or on the property, you should then grout them properly. Already when laying, you should pay attention to a sufficient minimum distance, in which you can spread joint sand later.

The correct laying of your paving slabs as preparation for grouting

A thorough preparation of the appropriate surfaces and the correct laying of the paving slabs is extremely important in order to be able to grout them correctly later and to achieve the desired work result. The grouting serves to hold the panels in place and prevent them from slipping or shifting. However, the joints should be designed so that no weeds can grow in them. To meet these requirements, various types of so-called joint sand are used for the filling:

  • quartz sand
  • sand
  • rock flour
  • ready mixes from the hardware store

Which joint material can be used for which purpose

Joint sand is so-called bulk material, which exists in different versions. The wider the grooves between the individual plates, the coarser bulk material should be used. The heavier the particles, the better they stay in place. If you use joint sand with larger components, they will not be washed out of joint so quickly, for example due to rainwater. By contrast, with only narrow grooves between the individual plates, you can only use materials with very small particles. It is very important in both cases that the material is incorporated accurately and conscientiously. Usually you do this work with the brooms. Thereafter, the sidewalk plates are shaken off, most easily with a vibrating plate, which you can borrow cheap if necessary in a machine rental.

What should be considered in the long term

Over the years, of course, weather influences affect the joints. Either rainwater flushes away the joint sand over time or the raw material becomes unsightly. In this case, it is advisable to renew the joint area and bring new material. When you use sand, it is much easier to introduce new materials than with durable fillers. You can simply put a new mixture of quartz sand or chippings in the grooves. This also has the advantage that the rainwater can better seep into the joints.
