Adhesive mortar for decorative stone and brick cladding

Cement-Based, Single-Component, Polymer-Modified, Flexible, High-Performance, and Stable Thick Bed Adhesive Mortar with Reduced Slippage

Application Areas:

• Suitable for both indoor and outdoor use.
• Applicable on horizontal and vertical surfaces.
• Used for adhering manufactured stone, paving stone, and brick veneer.

Advantages:

• Flexible and provides strong adhesion.
• Resistant to water and frost.
• Unaffected by temperature changes.
• Offers high stability and does not sag in vertical applications.
• Allows installation without the need for floor screeding.

Surface Preparation:

• The application surface must be fully cured.
• The surface must be free of dust, oil, tar, bitumen, paint, silicone, curing compounds, detergents, and formwork oils that may hinder adhesion.
• The surface should be moistened to remain damp before application. If the surface is highly absorbent, a primer should be applied before proceeding.

Mortar Preparation:

• 25 kg of STONEWRAP Manufacturing Stone and Brick Veneer Adhesive Mortar should be mixed with approximately 5-6 liters of clean water using a low-speed mixer until a lump-free consistency is achieved.
• The prepared mortar should be left to mature for 5-10 minutes, then mixed again for 1-2 minutes before use.
• The mixed mortar should be used within 1.5 - 2 hours.

Application Information:

• The material should ideally be applied with a trowel, and a double-sided bonding method should be used by applying the adhesive both to the back of the covering material and to the surface.
• The covering material should be placed within 15-20 minutes of applying the adhesive.
• For strong adhesion, press firmly using a rubber mallet.
• Consumption: Varies depending on the application surface.

Precautions:

• Avoid application at temperatures below +5°C or above +35°C.
• Do not exceed the recommended amount of water in the mix.
• Avoid applying on frozen surfaces, areas at risk of freezing within 24 hours, or surfaces exposed to direct sunlight and strong wind.
• Do not add additional water or powder to expired mortar.

Packaging:

• Available in 25 kg kraft bags.
