How To Clean Your Patio And Remove Blackspot Algae

Best Way to Remove Concrete Slabs on a Patio

In this article, I am looking to walk you through the easy to follow steps of how to remove patio blackspot from sandstone and natural stone and get your lovely patio looking like new again. At the end of our simple process, your paving or patio slabs will be free from dirt, algae, blackspot and those annoying lichens that always spoil its appearance! Dont worry, although you might have found this difficult in the past, with the right patio cleaner and a little bit of knowledge, patio cleaning and blackspot algae removal can now be a simple process.

Historically, trying to keep any patio clean used to be an arduous and time-consuming task. Particularly if your patio was laid with a variety of porous sandstone or Indian sandstone. Very few, if any cleaning products were effective enough as a patio black spot remover, with even algae and general dirt requiring pressure washing to keep them at bay. Not only can jet washing be a time consuming and arduous task, but it can also damage pointing. This, in turn, contributes to the paving slabs more porous and easier for the contaminants to become established and ingrained into the surface of the patio. This is particularly the case if the patio has been laid in vulnerable sandstone or Indian sandstone slabs. Blackspot and algae thrive on any variety of porous natural stone and this Inevitably leads to more regular and intense cleaning being required.

Most weeds can usually be pulled or scraped out of paving. Once youve gotten rid of the weeds, regular brushing can help to keep them at bay, as youll disturb them before they can get established.

How Can I Reduce My Patio Maintenance

Personally, I dont think brushing a patio with detergent, waiting for it to dry, then spraying it with a fungicide/biocide is a difficult task and it only needs to be done once per year.

But, if you really want to reduce the amount of time spent maintaining the patio, you could seal it with a waterproofer sealer.

This acts as a barrier and also prevents lichen from growing on the surface.

Weve created a price guide for driveway sealing, it contains links to sites where you can read reviews of the sealer products we recommend.

Ready For Some Outdoors Lounging And Entertaining Take Your Patio And Decking From Grey And Grimy To Looking Great

Patios and decking give us a useful outdoor space for relaxing and socialising, but its not always easy to keep them looking great. Once the summers over, the cold wet weather tends to hit them with a nice layer of green algae, while black mould spots, moss, mildew, plant debris and dirt can all make your decking look dreadful or your patio seem past its prime.

The good news is that it doesnt take a lot to sort this out, whether or not youve got a pressure washer. There are specialist fluids and detergents designed to deal with all these problems and get your patio or decking back to its best. In most cases theres no scrubbing or rinsing involved, and one treatment should keep you clear for around six months which should take you through most of the way to the next winter. Some will also work on any areas of paving, pathways, driveways or outdoor furniture, so everything in your garden looks great.

Which Chemicals Should Never Be Used On A Patio

Brick acid is perhaps one of the most corrosive products you can buy, its often advertised as a brick or patio cleaner but is far too abrasive for use on many patio slabs.

Ive used this chemical to remove hardened cement from hand tools, buckets and shovels. It quite literally dissolves cement and concrete and will eat into the surface of some patio slabs and make them more porous and brittle.

This is definitely one to avoid. It works great at removing cement and mortar but is far too corrosive for most patio slabs.

General Natural Stone Cleaning Products

Just like if you were caring for a wooden or carpeted floor, Natural Stone should be cleaned regularly to ensure that they continue to look their best for longer!

When it comes to exterior paving, over time, your slabs will weather which may see them change in appearance. The colour may become darker, for instance. However, inside, especially in areas with not much foot traffic, theres no reason that any Natural Stone shouldnt stay looking the same as when you laid them!
