If you want to sand pavement, you first have to know which sand is ideal. The type of sand and grain size play a role as well as the width of the joints and the method of application.
In a nutshell
- simple material for filling joints
- Quantity and grain size are crucial
- Quartz sand works well
- Sand can be spread under the pavement
- Layer thickness must be taken into account
Benefits of the sand
Sand fulfills important functions as a filling material for joints and as a base for stones or concreted surfaces. In doing so, it has several advantages. For example:
- easy to process and use
- available in different versions
- inexpensive to purchase
- ensures elasticity and a longer service life for paving stones
- numerous uses
What is one?
Einsanden is known under different terms. Sprinkling and grouting are just two of them. This means filling the joints between paving stones,
Terrace slabs and paving slabs.The quartz sand is filled into the joints and compacted. This has the following advantages:
- The surface remains elastic
- Frost damage is reduced
- The life of the stones is increased
- Shifting of the plates is prevented
- Water drainage is given
Type of sand
Quartz sand is suitable for filling joints but also as a layer under the pavement. This is comparatively rough and heavy. As a result, it offers a high degree of stability and is also ideally suited for more heavily frequented and stressed areas.
Grain size
However, one of the biggest questions when choosing sand is grain size. That is, the size of the individual grains of sand. Generally suitable are 0.1 / 1.0 mm up to 0.1 / 4 mm.
The smaller the grain size, the more sand is needed to sand the pavement. As a result, however, it can also be inserted more densely and is suitable for very small joint widths. The larger the grain size, the better the water can run off between the stones. It is therefore recommended for rainy areas and for a larger joint width.
Determine the joint width
The distance between the individual paving slabs depends on the size of the individual elements. If these are very small, the joints can also be narrow. Up to a side length of 15 centimeters, joints of two to five millimeters are sufficient. From 15 centimeters, the distance should be three to eight millimeters.
Note: Special joint sand is offered directly by some manufacturers of the panels or recommended in order to achieve an optimal result. There can also be an indication of the grain size.
Sand the plaster - instructions
If you want to sand in the plaster, it only takes a few steps. The following guide shows how to do it.
-
Calculate amount: How much material you need depends on the size of the surface, the grain size of the sand and the width of the joint. 1.4 to about 2.0 kilograms per square meter should be planned in any case. A small excess is recommended as you can also use it for refilling.
-
Apply joint sand: Distribute the quartz sand over the entire surface so that all stones are evenly covered. This process may have to be repeated several times.
- Stopping off: The joint filler is now swept between the panels with a broom until they are completely filled. If necessary, more sand is poured in.
frequently asked Questions
Sand is ideal, but it can wash out of the joints over time. A corresponding substructure with a slope and slabs connected by grout is also possible and more durable. If repairs are necessary, however, more effort is required.
Yes, in addition to crushed stone and gravel, it is advisable to spread quartz sand. These layers are compacted in order to produce a stable but nevertheless permeable base.
No, it is also ideal as a base and joint filler for other materials. Only with wood should it not be used or be used in conjunction with a stone base. Because the material is permeable, but still remains moist for a comparatively long time.
