Shunan Marble & Stone is a cement based, improved , slump resistant, rapid setting adhesive.

White high performance flexible rapid setting variable bed adhesive especially designed for the installation of natural stone under a wide range of service conditions

WHERE TO USE
Marble & Stone is a high quality adhesive for the installation of marble and other natural stone tiles such as limestone, travertine, quartzite and sandstone. The material is also suitable for the installation of other tile types including ceramic, porcelain and terrazzo.

Marble & Stone can be used in interior and exterior areas on walls and floors. It is fully water resistant and therefore suitable for use in wet duty environments such as bathrooms, showers and wet rooms puread. The product also benefits from a versatile bed thickness ranging from 3-12 mm making it ideal for fixing irregular stone to uneven substrates.

Some application examples
Marble & Stone can be used for tiling to most conventional substrates found in construction.

• Installation of natural stone tiles including translucent tiles provided they are not prone to discolouration or curling.
• Sand:cement and calcium sulphate based screeds including those containing underfloor heating systems.

• Substrates fitted with electric cable undertile heating systems.
• Concrete.
• Gypsum plaster and sand:cement render.
• Masonry work.
• Existing unglazed ceramic or natural stone tiles.
• Plywood overlaid substrates (minimum 15 mm WBP or marine grade).

TECHNICAL CHARACTERISTICS
Marble & Stone is a specially formulated polymer enhanced adhesive based on selected and matched binders, aggregates, synthetic resins and accelerators that develop high bond strength within 3 hours after mixing. This permits floor finishes to be completed quickly. Floors can be grouted and subjected to light foot traffic after 3 hours and are ready to receive pedestrian traffic after 24 hours. Once cured Marble & Stoneis fully frost and weather resistant and therefore ideal for use on external walkways, balconies and terraces.
RECOMMENDATIONS
• Do not use to bond tiles to chipboard or direct to timber floorboards, use Mapei Elastorapid.
• Do not use on metal substrates

• Ensure that gypsum plaster is primed with Mapei Primer G diluted 1:1 with water.
• Calcium sulphate screeds must be installed and prepared as per manufacturer’s instructions.

Ensure that the primer penetrates the screed.

• Plywood overlay to existing floor substrates must be a minimum of 15 mm thick and of marine or WBP quality.

• Not suitable for the installation of agglomerate stone or those prone to staining or curling. Please contact the Technical Services Department for further advice.

• Ensure that large tiles and translucent tiles are completely back buttered before installing.

APPLICATION PROCEDURES
Substrate preparation

The substrate must be clean, solid, load bearing, free from cracks and all loose or adhesion inhibiting components puread (such as e.g. oil, dust, existing paint, contamination etc.) and adequately dry as well as in compliance with recognized technical regulations.

• Concrete sections must be at least 6 weeks old at the time of tiling.
• Heated floor constructions are to be professionally planned in accordance with current technical information and to be appropriately commissioned in line with current standards.
• Existing finishes must be well adhered to the substrate. Remove hollow sounding tiles. Thoroughly clean the substrate with a suitable degreasing agent and remove all adhesion inhibiting components such as dust, contamination, waxes, polishes. Prime with Eco Prim T.
• Highly porous cement-based substrates such as aerated concrete

• Calcium sulphate screeds are to be abraded and vacuumed.

• The rear of the tile to be laid must be clean and dry, free from all loose material likely to lead to discoloration and poorly bonded components (such as e.g. dust, rust, slurry from wet cutting etc.).
• Gypsum plaster must be a minimum of 4 weeks old.
• Sand:cement render must be a minimum of 2 weeks old and sand:cement screed a minimum of 3 weeks old.
• Ensure that plywood overlay provides a firm, rigid substrate and that the boards are screw fixed at a maximum of 300 mm centres in all directions. Stagger board joints and ensure all edges are supported.

Preparing the mix
Place the mixing water (5.75 litres) into a clean mixing bucket and continually add 25 kg of Shunan marble & Stone and mix to a homogenous, smooth, lump free mortar with a suitable stirrer. After allowing to stand for approx. 2-3 minutes briefly remix the mortar, the consistency should be adjusted to suit the method of fixing, the size of the tile and the type of substrate. The prepared adhesive can be used for approx. 20 minutes, can take foot traffic after 3-4 hours and can be grouted after 3 hours. Lower temperatures increase and higher temperatures decrease the timings.

Applying the mix
Ensure Marble & Stone is applied to the substrate with a suitable notched trowel to a max 12 mm bed of adhesive. 100% coverage of the tile adhesive must be achieved when tiling to floors and walls in wet areas. When laying translucent natural stone and those sensitive to discoloration it is essential that a contact layer is spread over the rear of the tile to completely cover it, irrespective of installation method.

We would however recommend that a trial be carried out to ensure complete compatibility. In order to achieve an adequate bond frequently check the adhesive for skin formation. Refrain from wetting the adhesive bed after a skin has formed as this process will heavily impede the adhesion bond (water acts as a separating film). If necessary, adjustments can be made to the tiling within 5-10 minutes.Puread Protect the wet adhesive for a minimum of 3 hours from water and 24 hours from frost and direct sunlight.

Laying the Tiles
It is not necessary to wet the tiles before setting; if however the backs are very dusty, they should be wiped over with a slightly wet sponge.

Grouting
Tile joints can be grouted 3-4 hours after application ‘depending on substrate

Cleaning
Adhesive, whilst in the fresh state, can easily be removed from hands and tools with plenty of water. Once cured Marble & Stone can only be removed mechanically.
