Natural stone in this category get dirty easily and can be badly degraded as it is directly affected by the weather as sun, wind, rain ... The first important thing to do is making sure that natural stone is well protected with suitable sealing products. Sealing products must be weather-resistant, UV resistant, non-film forming. They must not change the color of stone products as well. Suggested products are  Pro TW Lux or Protex .

Powder chit circuit for outdoor column items also need special attention. Grouting powder must be weather resistant. Wrong type of grouting powder can melt under the rain or the sun. Then, it can penetrate into the stone, causing bad surface. It is costly and difficult to remove the old grouting.  

Besides, things like pollution, dirt, dust, leaves, pollen, mildew, mould, cobwebs and bird or bat poo can all accumulate and make your walls look old and dirty. Then, to keep the column looking great, do periodical cleaning and maintenance with specialized products for natural stone ( Neugel , Algafloor ) Depending on the type of stone, re-sealing should be done as consulted by professional natural stone maintenance care companies.
