Enjoy your garden and terrace to the full. Kids can have a field day, friends can spill their drinks, the grill can splash around. Don't be afraid. The bluestone has seen it all before. Weather takes care of everything! A careful wipedown with clear water from time to time will leave the stone looking bright. Give it a good cleaning session once a year, at springtime.
Cleaning of bluestone outdoors
Easily enough! Weather will do most of the work for you
After it has been laid
After it has been laid, leave the stone to dry out for about 2 to 3 months so that all humidity in the stone’s bed (glue or mortar) can evaporate. Clean it with clear water, sparingly and without soap. If you use soap during this period, humidity can become trapped, creating unsightly white traces on the stone’s surface.
Cleaning at the end of winter
Regular cleaning is not necessary because the weather does it all for you. Once a year though, thorough cleaning may be required. During spring, remove all the vegetation which gathered around the stone during winter. Use water with a dash of bleach, let it soak, brush it and rinse with water. Alternatively, you can also use out of a product from the Lithofin range.
Blue Limestone from Hainaut does not require specific protection. If needed, the areas which are more exposed to stains like BBQs and tables can be protected with either Lithofin or Imperplex products, or ‘the old way’ with Marseille soap flakes. Soap up and scrub without rinsing and you’re ready for summer! One or two cycles of treatment should be enough.
Let the stone dry out for 2 to 3 months after it has been laid.
Give the stone a yearly clean during spring with water, bleach and a brush.
Use pH neutral products.
Carefully follow the product manufacturer’s instructions and dosage advice for natural stone. First do a test on a hidden part of the stone.
Use acidic, chemical or anti-scale products.
