Technical Characteristics

Planitop Fast 330 is a grey-coloured one-component cementitious mortar with very low emission of volatile organic compounds (EMICODE EC1 R) made using special cementitious binders, selected aggregates materials, synthetic resins and special additives according to a formula developed in MAPEI’s Research & Development laboratories.

When mixed with water, it forms a blend with good workability which may be applied on vertical surfaces by trowel, characterised by its high bonding strength to all substrates normally used in the building industry.

Planitop Fast 330 hardens quickly even when applied in thick layers without shrinking or cracking, and forms a strong layer suitable for laying ceramic, glass mosaic and stone finishes.

Planitop Fast 330 meets the main requirement of EN 1504-9 (“Products and systems for protecting and repairing concrete structures: definitions, requirements, quality control and conformity assessment. General principles for the use of products and systems”) and the minimum requirements of EN 1504-2 coating (C) according to principles MC and IR (“Concrete surface protection systems”) and is classified as GP (“General purpose mortar for internal/external render”), category CS IV according to EN 998-1.

Recommendations

• Do not mix Planitop Fast 330 with cement or other products and never add water to the mix once it has started to set
• Protect the surface to avoid the water evaporating too quickly in hot and/or windy weather
• After applying Planitop Fast 330, protect the surface from water for at least 4 hours at 20°C and 24 hours at 5°C, and in all cases, until it has hardened
• Apply at a temperature between 5°C and 35°C
• Do not leave bags of Planitop Fast 330 exposed to the sun for long periods before use
• Do not use this product on flexible, deformable substrates such as wood and wood conglomerates, metal, rubber, PVC and linoleum

Application Procedure

Preparation of the substrate

The substrate must be cured, compact and free of dust, loose parts, oil, grease and traces of paint and adhesive.

Surfaces exposed to direct sunlight or winds must be wetted beforehand.

Particularly absorbent substrates (such as bricks, lightweight concrete blocks, etc.) must be wetted before applying Planitop Fast 330, especially when applied in thin layers.

Gypsum substrates and anhydrite screeds must be perfectly dry, hard enough for the final intended use and free of dust. They must also be treated with Primer G.

Concrete surfaces must be well cured, clean, free of dust and cement laitance and, where necessary, treated with Eco Prim Grip.

Smooth substrates and substrates with low or no absorbency, such as ceramics, terrazzo or concrete with a finish of smoothing and levelling compound, must be cleaned, mechanically abraded and treated with Eco Prim Grip.

Preparation of the mix

Pour a 25 kg bag of Planitop Fast 330 into a container with 4.5-5 litres of clean water while mixing (18-20 parts of water per 100 parts in weight of Planitop Fast 330) and mix with a low-speed mixer to form a smooth, lump-free blend. The blend remains workable for approximately 20 minutes (at 20°C).

Application of the mix

On walls: Apply a feather edge layer of Planitop Fast 330 on the substrate to form a perfectly buttered layer and then immediately apply the product at the thickness required to level and even out the substrate in a single layer (up to a maximum of 3 cm).

If thick layers are required, Planitop Fast 330 may be applied with a smooth trowel by pressing it down well onto the substrate and then levelling off with a metal straight edge (final finishing with a sponge float).

On floors: Apply the mix with a long metal pallet knife or trowel.

Laying of coatings and waterproofing Waterproofing layers of Mapelastic, Mapelastic Smart and Mapegum WPS may be applied after approximately 24 hours at 20°C. Ceramic tiles, stone (not sensitive to moisture) and all types of mosaic may be laid after approximately 4 hours at 20°C and after 24 hours at 5°C.

Curing

Protect the surface against water evaporating too quickly during hot and/or windy weather and avoid the mortar coming into contact with water for the first 4 hours at 20°C and for the first 24 hours at 5°C.

Cleaning

Tools and containers may be cleaned using water while Planitop Fast 330 is still fresh.
