Niveland^® 30R

Technical Caracteristics

Product based on special cements, selected aggregates, resins and additives.

Advantages and Uses

• Levelling uneven interior floors.
• High mechanical resistance and excellent adherence over cement mortar and concrete.
• Can be applied manually or by pump.
• Good workability.
• For smoothing floors in interior residential buildings with foot traffic before installing the final floor covering: ceramic tiles, parquet, carpet, PVC, lino, etc.
• Very smooth finish and durable hard surface.
• Suitable for floors with underfloor heating.
• Up to 30 mm thick with added aggregates.

Suitable Substrates

• Concrete, cement or floors with appropriate or similar strength. For use on other substrates, please consult our technical department.
• Substrates must be resistant, stable, sound and clean, free of dust, demoulding agents, organic products, etc.
• If necessary, prepare the substrate mechanically so that the surface if free from grout and has the appropriate porosity.
• Before applying NIVELAND 30 repair any cracks and/or fissures with products from the Niveland, Paviland or Morcem Rest ranges, according to the nature of the substrate and type of repair to be carried out. 
• Apply the primer Paviland Prymer R to avoid any air bubbles in the covering and to improve the adherence of the substrate.
• Before applying the paste, ensure that the residual humidity is below the recommended level (lower than 3%).

Application Procedure

• Use a mixing pump in 2 stages, adding water until the required fluidity has been obtained.
• Spread the product with a levelling trowel until the required thickness has been obtained.

• Mix the product with water (6 - 6.5 litres per 25 kg bag) mechanically, with a low speed mechanical mixer (approx. 500 rpm) until a uniform mixture without lumps has been obtained. It is essential to add the exact specified amount of water to avoid product separation, shrinkage and lowering of strengths.
• Let the mixture stand for 2 minutes and remix.
• Pour the mixed product over the fixing substrate and spread with a levelling trowel until the desired thickness has been obtained.
• In both cases it is recommendable to apply with a spiked roller, briskly, in both directions so as to avoid trapped air.
• The minimum recommended thickness is 2 mm and the maximum is 15 mm applied in one single coat.
• It is possible to use a thickness of between 15 and 30 mm. In which case, add 30% (7.5 kg per 25 kg bag) of quartz sand, grain size 0.6 – 1.0 mm or 1.0 – 2.0 mm. The addition of aggregate makes the mortar lose some of its "self-levelling" properties.
• Respect structural joints and carry out perimeter and portioning joints.
• NIVELAND 30 must be protected, as it is not an appropriate material to remain uncovered.

Recommendations

• Do not apply in temperature under 5ºC nor above 30ºC.
• Do not apply when there is a risk of frost, strong wind or direct sun.
• Not recommended for exterior use.
• Do not apply on floor with humidity or with a risk of having it.
• Use gloves or protective goggles when applying product. Keep out of the reach of children.
• The only possible addition is that given in the user instructions for thicknesses above 15 mm.
• Once the product has been mixed and the resting time has occurred, do not add additional water.
• For floors larger than 20 m² or longer than 10 lineal metres, it is advisable to make partitioning joints, delimiting panels with 6 mm joints that can be sealed with PUMALASTIC MS or PU.
• Movement joints on the original substrate must be respected and permiteral joints made.
• The surface coat must be protected from drying too quickly, especially in conditions with high temperatures and/or strong winds.
• Before laying the final flooring check the residual humidity of the floor and confirm it is adequate for the type of flooring to be installed.
