Summary: In this DIY guide we show you all you need to know about how to clean and maintain a patio or paved area.
When it comes to stains found on paving and patios these are often a result of overspill from pointing the joints with cement mortar.
By regularly brushing your patio over, this will remove any debris and dirt that is sitting on the surface.
If you have a large industrial size pressure washer, some of these pump out over 2000 psi in pressure. Also, if they look tatty and worn they can completely ruin the look of your patio or driveway area. Many, if not most patios are laid using patio slabs and the slabs themselves tend to be quite porous in nature (water and moisture absorbing). As I’m sure you have gathered by now, they require regular maintenance to look their best that includes sweeping and washing but there is also another step that you can take to aid their looks and longevity and that is to seal them using a specialist patio sealer (or block paving sealer in the case of block paved surfaces).
There are many different paving and patio sealers available on the market today including those for more specialist paved surfaces such as Indian sandstone, Limestone and Travertine surfaces.
Due to the vast selection of different sealers it can be a little confusing to know which one to use for your particular surface so always check the manufacturer’s suggestions on the packaging and using the wrong sealer could potentially destroy your paving or patios surface.
A worthy point to note is that this is not a one stop solution that will protect your paved or patio surface for ever, you will still need to maintain it through sweeping and cleaning.
Holding the bolster chisel at around an angle of 30°, position the tip at the base of the concrete or mortar you need to remove. Additionally, ensure that the tip of the chisel is flat and level with the surface of your path or slab. Once all the lumps are up and you have removed as much of the remainder as possible with your wire brush you may be left with a stain on the paving or concrete.
I'm pretty sure anyone that has a patio, paved surface, concrete path, concrete driveway or almost any other outside surface, if they went outside and checked it now that somewhere on it will be a green patch of growth.


As said, almost all patios or paved surfaces will feature a degree of algae growth but it can be more extensive in wetter climates as the algae itself thrives off the fact that moisture, particularly rainwater, will dissolve some of the minerals in the surface its resting on that it can then feed off of. With this in mind, the key to preventing moss growth is to keep your paving or patio area free from dirt buildup. Lichen growth normally appears as black or white spots on a surface and when tiny can often be mistaken for stains.
The grayish-white spots on this pool deck may indicate sealer diffusion, a condition in which the sealer lifts from the concrete.
You will learn how to regularly brush your patio and paved areas to ensure they remain free of dirt and dust, how to wash your patio or paved area and what to use, how to clean and maintain any joints and also how to remove moss, lichen and algae to give your out door area that new show home look. Washing up liquid is the best to use but you can use certain floor cleaners, just make sure that they are acid free as acid based cleaners can react and damage some concrete or stone surfaces. The scrubbing action and soap combined will loosen any surface dirt and grime from your paving or patio. If you would like more information on paving and patio sealers there is a very good guide here.
If the chisel is at too acute an angle then when it is struck it will simply dig into the surface of your path or patio.
Next, sprinkle the mixture over your paved or patio surface and leave it for a few minutes to get to work on the algae.
This is obviously not a road you want to go down due to the inevitable damage that will be caused to your patio or paving surface.
Then, wash off with soapy, boiling water whilst giving it a good scrub at the same time (don’t forget to wear old clothes, goggles and gloves).
This is due to the fact that the lichen has removed some of the minerals from the surface while it has been feeding off of them.
Efflorescence is a chalky white salt residue that can occur with any product containing cement.


In some cases a little hard work with a brush and some soapy water can really give tired and un-cared for pathway a completely different look. In much the same manner as the washing up liquid and brush method, work your way over the surface of your patio or pathway removing as much surface grime as possible. Be careful at this point as, again, you don’t want to damage or mark the actual surface of the path. As moisture migrates up to the surface of the concrete, it carries along with it calcium salts from within the concrete. As with most decorative concrete issues, it could be a combination of both of these things, with a little efflorescence thrown in for good measure. This phenomenon, where the sealer is no longer adhered to the concrete, looks a lot like efflorescence from a distance, but on closer inspection is actually more gray or cloudy.
This white, dusty, scaly salt can be minimal or dramatic, depending on the amount of free calcium salt present in the concrete.
Lighter-texture seamless patterns with simple sawcuts or large light-texture stone patterns work best. Exposure to rain, standing water, and sprinklers only make the situation worse, as water triggers the reaction and creates more efflorescence.Efflorescence is not as noticeable when it occurs on gray concrete, but even a little efflorescence on colored concrete can be a contractor's worst nightmare. The small air gap that now exists between the sealer and concrete causes the light to diffuse and create the grayish-white cloudy look. To avoid the problem altogether on future projects, consider using a colored curing compound or cure and seal to match the color of the concrete.
