A Guide to Cleaning and Maintaining Your Pavers

Cleaning Paving Stones

Keeping things clean can sometimes be a chore but the end results always justify the hard work. Just picture your car and how fantastic you feel when it looks as good as it did the day you bought it. Everyone wants to keep things looking stylish, sleek and clean, and pavers are no different.

If you’ve installed pavers around your yard, then we have some cleaning and maintenance tips for you. Today we’ll address not just the cause and treatment of different types of stains, but also some preventative measures you can take.

Fighting Fats and Oils

Oil and fat stains can be caused by a range of things – from your barbeque, to food and even leaking motor oil.

Treat these stains with a degreasing agent - it may need a few attempts for success.

If the stain does persist it may cause a shadowing to appear on the paver that will lighten with age.

Mould Protection

A lack of sun or damp conditions may cause mould to appear on your pavers.

To fix this, scrub the area with a hard brush or broom (not steel), then spray it with weed killer and wait a few days. After this, lightly brush the area using hot soapy water.

Tannins and Resins

New timber or surrounding trees might cause these stains!

By scrubbing the area with hot water and oxalic acid (120 grams/4 litres) and rinsing well with fresh water, you should be able to remove your stain.

If not, you can wet the surface with bleach containing sodium hypochlorite and let this sit without rinsing. This may lighten your pavers though, so think twice before using this method for darker colours.

Cement Stains

If you’re doing work with cement, you may end up with these stains.

Scrubbing the area with a hard brush (not steel) or high a pressure water cleaner should have some success, depending on how long the concrete has been set.

If this doesn’t work, a professional paving contractor can use hydrochloric acid.  This may strip the top surface or cause discolouring though, so you may want to consider replacement pavers instead.

Relocating Rust

Garden furniture, construction materials and nails are all common causes for rust on your pavers.

Scrubbing with a hard, non-steel brush or broom and soapy water may remove some of the rust spots. This treatment is tricky though, and you may want to replace your pavers if you don’t see success.

Mulch, Soil or Sand

Leaving mulch, soil or sand on a wet surface can cause longer term straining.

You can sweep away any loose particles as soon as you notice them, and treat the rest of the area with hot soapy water (ratio 0.250:5 litres), scrubbing this with a hard brush or broom (not steel).

Mulch and sand can leach into your paving, resulting in permanent stains. If this happens, the only thing you can do for this is to wait for them to lighten with age.

A Quick Word on Prevention

To help to protect your pavers from all these stains and more, it is important to have your pavers sealed. Sealants can also protect your pavers from becoming exposed due to long term contact with salt (usually caused by swimming pools or sea spray in coastal areas.)

Ensure the sealant you choose is the best product for your pavers and always follow instructions. Inappropriate sealants and incorrect application can lead to other long term effects, including discolouration.
