So, the time for outdoor fun has come and you need to straighten up your yard and to refresh the patio. And as you probably know, part of its maintenance is repointing the paving slabs. Or you are, maybe, a new home owner, in a process of laying new patio slabs or garden paths, then probably you need to get familiar with how to point paving slabs for the first time.
This is an important task, since properly pointed paving slabs ensure the neat appearance of your patio intact. And most importantly, pointing or repointing the patio correctly prevents your hard exterior surface from frost and water damage. Last but not least, the lack of cracks in the newly filled joints, after you’ve pointed your patio, will also prevent unwanted vegetation from growing between the patio slabs, which can give the patio a bit of a neglected appearance, as well as affect its structural integrity.
The task may seem a bit time-consuming but if a few simple steps are followed, the result will be satisfying and rewarding!
So, if you:
Then just keep on reading to learn how to point paving slabs the easy way!
There are more than one ways used for pointing paving slabs. They mainly differ by the pointing mixture used in the process. For instance, with some methods, the paving slabs need to be wetted slightly beforehand, whereas with others – there’s no need for that.
In any case, the most traditional patio pointing technique uses cement-based mortar that needs to be mixed with water, first, while some of the more contemporary methods use a ready dry mix of sand and cement, a resin compound or a polymeric type of pointing material.
Also known as “rigid pointing”, the technique requires mixing sharp or silver sand (depending on how wide the joints are) with cement, in order to create a mortar mix by adding water to it. Usually, the sand-cement ratio used is 1:1. Only paving slab joints larger than ½ an inch require a sandier mortar with a ratio of 3:1.
Note that this pointing method is weather-sensitive and needs to be used on a completely dry, but not too hot day. The paving slabs that need pointing also have to be free of moisture.
This patio pointing technique may require the opposite of the previous method. If you use a ready mix of sand and cement, then you need moisture for the material to set in right, so a humid day would be just right for the job. The patio slabs also need to be completely saturated. The reason is that the dry substances contained in the ready compound need moisture so that the product does its thing more effectively. This pointing method ensures the flexibility of the joints, as opposed to the “rigid” wet mortar method.
So, how does the patio pointing process go?
Time needed: 2 days.
Give the patio a good clean and also clean the joints from debris.
If you choose to use the ready compound method with a dry mix of sand and cement, don’t forget to saturate the paving slabs, first. Now is the right moment to do it. Disregard this step, if you are using the mortar method, where you mix the substances well with water, first.
Make sure you stuff the joints completely with mortar, without leaving any air bubbles, since they may cause cracking of the pointing material later on.
Use a metal tool of some sort to compress the mixture without leaving any gaps and air pockets, in order to achieve a strong patio structure. The moisture in the air and from the ground underneath will help with the setting process.
Once you’ve swept in the dry compound (or stuffed the mortar mix) well into the joints, all you need to do is to remove the excess mixture from the paving slabs. It is recommended to sweep across the joints, in order to leave them undisturbed.
Try to remove the excess pointing material from the patio as quickly as possible to avoid staining of the paving slabs.
Allow about 48 hours without foot traffic, so the pointing compound can set in the joints correctly.
Now the patio pointing is completed, so you can enjoy using it at your leisure.
The process of repointing a patio goes in the same way as the one described above. There are just a couple of steps that you need to take beforehand:
What’s left is to follow the steps described in the pointing paving slabs process above.
For this reason, experts claim that once you’ve installed your patio with a resin-based pointing material, then no repointing will be ever necessary. In contrast, with the “rigid” mortar or the ready dry sand and cement mix methods, you’ll need to consider repointing your paving slabs every once in a while.
So, keep in mind this if you’re wondering about which pointing method to go with.
Now, you know how to point and repoint paving slabs on your own.
