K-STONES BASIC (NATURAL BASE PLASTER)

K-Stones Basic is a versatile high performance natural mortar of light beige color suitable as base plaster, single layer plaster and building mortar for stone and brick masonry. It is also suitable for pointing rock masonry.

It is a hydraulic base plaster of medium granulometry (particle size 0-2.5mm) 100% eco-friendly with very high grip and excellent breathability.

The composition of K-Stones Basic is based exclusively on natural raw materials (natural hydraulic lime NHL 3.5, natural pozzolan, pyritic river sand, dolomitic limestone etc.). It does not contain any cement, toxic substances or petrochemicals.

Thanks to natural hydraulic lime it is easy to apply and has excellent workability. A trowel or a mechanical sprayer can be used for initial layering.

APPLICATION INSTRUCTIONS

PREPARATION

The substrate must be clean, fully cured, solid and sound, uniform and homogeneous.

The substrate should be sufficiently stable and free of dust, grease, loose materials, etc.

Prior to application we thoroughly wet the substrate.

MIXING PROCEDURE

Add approx. 5 liters of water per 25kg bag, in a container and gradually add the bags mixing with a low speed plaster mixer.

Only mix whole bags.

Mix for approximately 5 minutes, until a uniform paste is achieved (initially it will appear dry, do not add water, just keep mixing).

APPLICATION

Use a trowel or other appropriate tool for initial layering, pressing to ensure that no air remains trapped. Apply additional layers if necessary and press to ensure that no air remains trapped between the layers. Level with a float and finish with a soft sponge float if a very smooth finish is required.

Discreet surfaces must be applied uninterrupted to avoid visible joints, always finishing on the edges of intersecting surfaces.

For the first 24 hours after initial application keep surfaces damp with light uniform sprinkling. Quick drying must be avoided as with all plasters when curing.

Wash tools with water.
