What is polymer?
Molecules that form chains are referred to as polymer. As in the area of joint sand, this can be salts and minerals. These combine with the sand that is worked into the joints. The resulting natural high pH makes it impossible for plants, including weeds, to grow in them.
Why do you need joint sand?
A good sand for grouting the laid paving stones must consist of pressure-stable material. So crushed sand that adapts and retains its position. Quartz or granite sands are often used for this. In the end, they are compressed. The advantage of paving over concrete is not only the more attractive appearance, but also the floor can still work, which means minimal movement. This prevents cracks and the covering lasts much longer. Most of the joint sands, however, are washed out by the weather. Small floor organisms help quickly and if you are unlucky, one day you will find that the joints have holes and the joint sand is distributed all over the place. This allows the weeds to settle quickly and, over time, the paved area can hardly be recognized.
Joint sands with clay content dry out quickly, those with plastics may not necessarily be the most natural way and those with asphalt are difficult to work in.
Here the polymer joint sand is used. The joint sand is mixed with the polymeric molecules. Of course, these molecules are much smaller than the joint sand itself and settle in the gaps. This results in a higher density. The changed pH of the sand now creates an acidic environment in which no plants can grow. As all of this happens in a natural way, the polymer joint sand is very ecological. It is also permeable to water and can also be used for repairs.
Use polymer joint sand
It is clear that joint sand is required for all types of paving work that should last longer and must form a flat surface. No matter whether for sidewalks, garden paths, or patio slabs. Natural stones are also incorporated in this way and, of course, the concrete paving. The Romans have already shown that this works well and for a long time.
You can buy the polymeric grout sand already mixed in stores or mix it yourself. The processing, however, remains the same in the end. All you need is:
- a bucket of grout sand
- a broom to sweep the sand
- a compressor (vibrating plate) and
- Pressure sprayer
The polymer joint sand is simply placed on the paved surface and swept in. Please make sure that it is swept in thoroughly and cleanly and that there are no coarse foreign bodies in it. Otherwise these will also be incorporated. The joint sand and the surface to be jointed must be absolutely dry! After thorough sweeping, the excess sand is brushed off. The rüttelplatte should have a rubber attachment, this prevents damage to the plaster. Now the surface is shaken once long and once across so that the joint sand has its desired position in every direction and everything is really where it should be. The polymer joint sand now only needs to be moistened with a pressure sprayer. He does the rest by himself.
Even damage or repair work can be quickly completed with the joint sand. Incorporate - compress - activate with water - let dry - done. Basically the principle is very simple and skillful hands can achieve wonderful results very quickly.
Where can you buy polymer joint sand?
The finished mixtures of polymer-bonded joint sands can be bought in the hardware store around the corner. They are easy to transport in practical 25 kg bags. For example, for a joint width of 10 mm, a stone size of 40 x 40 cm requires about 4 kg / sqm. The joint sands are also available in different colors. You have to expect around 50 euros for a 25 kg bucket.
If you prefer to mix it yourself, the polymer binder is also available without sand, in commercial quantities of 1 kg each. 1 kg is enough for 20-25 kg of quartz sand. Please pay attention to the right quartz sand here, not everyone is suitable for grouting and mixing with the binder. For this you can count in about 20 euros.
Advantages and disadvantages of polymer joint sand
Perhaps the only disadvantage is for customers who are reluctant to work with salts for the sake of nature.
Otherwise, the polymer joint sand offers several advantages over normal joint sand:
-
- quick and easy to process
- lower expense
- high longevity
- Can be repaired
- Weed-inhibiting
- without plastics or chemicals
Conclusion
If you need a long-lasting grout sand that is permeable to water but does not wash out and also keeps weeds away, you are very well advised with the polymer grout sand. It is easy to incorporate and works without chemicals and plastics. In the meantime, all good hardware stores are leading him.
