Maintenance and renovation

The choice of finish is also important for maintenance. For example, a polished stone will be easier to clean than a flamed stone. Therefore, coatings or impregnating agents are used to make maintenance easier. The absorption of a material is also an important factor. The smaller the absorption factor, the easier to maintain, also here coatings are possible that simplify maintenance.

Natuursteeninfo BV works with LITHOFIN maintenance products. These are easy to order.

CAUTION: Never mix different maintenance products.
Due to the presence of, among other things, solvents in the various types of maintenance product, there is a risk that the protective properties will be negatively affected.

Never use products that close the pores, they slow down the drying process and can cause damage because the moisture cannot evaporate from stone. For very porous limestone types, only clean by vacuuming, possibly use some Marseille soap later, 1 hand per 10 liters of water, never apply to polished surfaces and compact stones.

Checking whether the floor is dry should always be done with a moisture meter, especially before applying an impregnating agent. It is of course possible to have this done by Natuursteeninfo BV.

Renovation: after construction work or local intensive use, a floor may be dull, dirty or damaged. These problems can in most cases be solved by:


Grinding / polishing on site: with the addition of a lot of water, a layer of the floor is mechanically grinded, the water serves to cool the discs and to drain the sludge, with increasingly finer discs the original gloss is obtained, difficult angles are regrind small tools. Advantage: height differences are eliminated, so that one can speak of a certain added value. This is the most common way of working in Italy / Greece, among others.


Crystallization: application for calcareous rocks. This treatment makes shallow scratches less visible, but other damage remains visible. A chemical reaction is caused in the top layer with calcareous stones using chemicals and a polishing machine. It is a reaction of calcium carbonate with magnesium fluorosilicate and phosphorus or oxalic acid. In the presence of a catalyst (iron). This creates a harder top layer that is less permeable to vapor, as well as a glossy layer.
