5 Steps for a Cleaner Patio

Monday 12th August 2019



Do you remember what your patio looked like when it was first laid? Undoubtably a lot better than it does now! Don’t fret - it’s easier than you might think to get it looking good as new (or at least nearly new). 

Step 1 - Remove weeds 
Weeds crop up in almost every patio - usually in the joins between each paving slab. Generally the weeds grow as a result of the compound filler or cement between the paving stones degrading, allowing room for the weeds to sprout. There is no quick way to remove weeds from the patio - just put on a pair of gloves and walk around the patio pulling weeds as you go. 

To keep the weeds away use a product like Roundup Weed Killer, which is especially designed to be used on surfaces like tarmac and paving stone, and is non corrosive to paved areas. Always follow the manufacturers instructions. 

Later, in step 5, we’ll use a filler material to replace the degraded filler between the slabs.

Step 2 - Prepare the surface with a cleaning solution 
The easiest cleaning solution that can be made at home is simply hot soapy water. However, this may not be tough enough to remove some of the more stubborn patches of algae or moss. Our recommendation is Patio Magic, a concentrated cleaner designed specifically to tackle algae and moss on hard surfaces.

A heavier duty product which can be used for the same purpose is Red Label. This product is, however, very caustic which may be damaging to some specific types of slabs. Check manufacturers instructions before use.

Step 3 - Scrub
Using a hard bristled brush, scrub the paved area rigorously using a circular motion. Some may argue that this is an unnecessary step, however we believe that including this step will produce the best results.
Step 4 - Pressure washing
Pressure washers greatly reduce the amount of time and effort required to clean your patio. Starting at one end of the patio, blast the dirt away in a sweeping motion, being careful not to bring the nozzle too close to the paving, or to hold the nozzle in one position for too long, as this can damage softer slabs. 

Once you have cleaned the patio from one edge to the other then use a lower pressure setting to rinse away all the remaining puddles of mud, dirt and grime.

Kellys have a wide range of pressure washers available here and here.

Step 5 - Refill the gaps
Wait for the patio to dry and then use sand, cement or compound filler to fill the gaps between the paving slabs. The combination of using weed killer in step 1, along with filling the gaps with filler should prevent weeds returning for some time. If the occasional weed does appear then just pull it out and refill the hole with filler.

That’s it! Following these 5 steps should result in a drastic improvement in how your patio looks!
