Lithos Arte®

The substrate must be clean, dry and capable of bearing a load. It must also be free of adhering parts, impurities and any substances that may prevent adhesion.

Iron residues, e.g. brackets, bolts or other anchors, must be removed from the surface being repaired.

The depth of the damaged area must be increased to 1 cm below the surrounding stone surface. The area must also be roughened.

Drill holes with a diameter ± 5 mm into the surface being repaired and insert anchor rods or wood screws made of stainless steel or brass.

If the area to be repaired is very large or has overhanging parts, use a brass/stainless steel wire to bind the anchor points (never use steel or iron).


Impregnating the substrate:

Use a brush to apply the Lithos Arte® liquid to the surface being repaired. This treatment ensures that the substrate is etched.

Highly complex shapes and profiles are very easy to repair because the mortar sets very quickly. This means that thick layers can be applied without any delays, even overhead.

Using a scraper or trowel, apply the mortar to the liquid-covered substrate up to a height of 1 to 2 mm above the profile being repaired.

After 10-25 minutes (depending on the ambient temperature), the mortar has set sufficiently to allow the surface to be scraped with a scraper until it is flush with the desired profile.

Finishing:

During the setting process (fully set: after 24 hours depending on the ambient temperature), the colour gets visibly darker. This is due to the polymerisation reaction. Therefore, once the material has set, the surface must be sanded in order to achieve the same surface texture and colour as the original natural stone.
Once fully set, the surface can be hardened, cut or milled.

A water-repellent treatment can be applied once the material is fully set.

The colour of the dry Lithos Arte® can be changed slightly by mixing with Lithos Arte® powder, which is available in various colours.

Lithos Arte® must not be applied to frozen substrates.

Once it has hardened, mortar must not be made workable again by adding either water or more wet mortar.

The type and duration of the reworking and surface treatment will influence the colour.

Slight deviations in colour between different batches are possible.

Do not use on gypsum-based substrates.

Mixing tool, brush, filling knife, sanding board, stonemasonry tools

Clean tools with water while the material is still fresh.

If stored in sealed, original containers in a cool, dry place, the product will keep for at least 24 months.

Resistant to frost

Apply to a large enough trial area to determine the precise amount required.

The characteristic data of the product were calculated under laboratory conditions at 20°C and 65% relative humidity.

The colour that is obtained after drying and hardening depends on the ambient conditions and the processing method. For instance, a freshly smoothed surface will be lighter than one that is smoothed later or roughened. Different grain sizes of the same product may lead to slight differences in colour. Substrates soaked from the back may cause discolouration.

Always set up a trial area/trial areas first.
