Paviland^® Recrecido

Technical Caracteristics

Product based on cement, selected aggregates, and additives.

Advantages and Uses

• Screeding and levelling of interior and exterior floors for pedestrian traffic. 
• Suitable for radiant heating floors.
• Easy to apply, providing surfaces with high flatness. 
• High mechanical strengths.
• Floor screed for thicknesses between 10–60 mm.
• Particularly suitable as a screed prior to the installation of ceramic tiles in exterior applications.

Suitable Substrates

• Concrete, mortar floors and similar.
• Substrates must be resistant enough, stable, sound, and clean. Free of dust, release agents, organic products, etc.
• Prior to the application of PAVILAND RECRECIDO, any honeycombs and/or cracks present in the substrate must be properly repaired.
• Before applying the product, make sure that residual moisten is below the recommended one (bellow 3%).
• Apply Paviland Primer R to avoid the formation of air bubbles in the render and improve its adhesion to the substrate.

Application Procedure

• Define and mark the maximum levels of the screed layer.
• Mix the product with water, starting at 16% of the dry weight until the desired consistency is achieved, without exceeding 18% (between 4.0 and 4.5 litres per 25 kg bag). Mechanically mix using low-speed mortar mixers (< 500 r.p.m.) until a fluid and homogeneous paste is obtained (free of lumps).
• Apply the mixed product by pouring or pumping it onto the substrate and spread it using a levelling trowel, smoothing, and correcting any imperfections.
• For large areas, it is recommended to pump the mixture using twin-spiral mixers capable of delivering 20–40 L/min. This procedure helps to optimise installation times.
• Once the product has been spread, it is recommended to pass a spiked roller over the surface to remove air bubbles, then re-smooth with the levelling trowel to achieve a completely smooth surface.
• 10 to 60 mm thickness.
• Respect structural joints and create perimeter and partition joints.

Recommendations

• Do not apply the product under 5ºC nor above 30ºC temperature.
• Do not apply under the risk of frost, rain, heavy wind, or direct sun light. Do not apply on moisten floors.
• Do not add sand, cement, or any other material that may alter the original formulation. 
• Once the product has been mixed, and its resting time has elapsed, do not add any water.
• For floors with a surface area greater than 20 m² or a linear length exceeding 10 metres, it is recommended to create partition joints, dividing the surface into approximately square panels with a minimum width of 6 mm, filled with PUMALASTIC PU.
• Avoid contact with perimeter elements by creating perimeter joints with a minimum width of 6 mm and a depth between 10 and 30 mm, filled with PUMALASTIC PU.
• Before installing the final floor covering, check with a carbide hygrometer that the residual moisture is < 3%.
• For exterior applications, it is essential to protect the screed from direct sunlight for the first 24 hours and from rain until the final floor covering is installed.
