how to clean poured limestone path eg detergent type and power washer pressure.
Welcome to the Bunnings Workshop community. It's fantastic to have you join us, and thank you for sharing your question about cleaning poured limestone paths.
Before I make any recommendations, would it be possible for you to post a few photos of your limestone path? This will give our members a chance to assess its condition. We can then make suggestions on how to clean it.
Limestone has a very porous surface and when cleaned too vigorously could damage its surface or leave it open to even more dirt and debris. I often recommend sealing limestone with Crommelin 15L Limestone And Sandstone Sealer once it has been properly cleaned.
We look forward to seeing your photos.
Thank you for posting those photos of your limestone path. I suggest using 30 Seconds 5L Outdoor Cleaner Concentrate in combination with an Oates Long Handle Deck Scrub Brush or similar. I recommend using only your garden hose to wash off the path as a power washer will damage the surface of the limestone.
Once the path is clean and totally dry, I recommend sealing it with Crommelin 15L Limestone And Sandstone Sealer.
If you need further assistance, please let us know.
Hi EricL, Thank you for your advice. 30 seconds proved great for removing algae, coverage was as per label. Now to sealing as recommended. Thanks again.
I'm glad to hear that the 30 seconds did a great job of removing the dirt and algae on your path. Please note that before applying the sealer to your path, it's important to make sure that the weather will be sunny with no chance of rain for the whole day.
Once you've sealed your path, please don't forget to post a photo of the finished project. I'm sure our members would be keen to see what the path looks like once it has been sealed.
Thank you very much for the update.
