Mapei Planitop 100

Mapei Planitop 100 is a single component fast-setting fine mortar for repairing and finishing porous or chipped cement based surfaces.

Mapei Planitop 100 has been formulated with special cement binders, selected fine grain aggregates, additives and polymers to provide excellent adhesion to all cement based surfaces due to its high synthetic resin content. Planitop 100 forms a compact and mechanically strong layer after hardening and is ideal for small repairs, evening out surface imperfections or for finishing cement facings repaired with Mapegrout products.

Best Uses

Mapei Planitop 100 is a light grey powder mixed with water or water and sand and is ideal for small repairs to prefabricated concrete panels, steps, beams and pillars or for rapid finishing of cement renders, lime and cement mortar and concrete facings. Planitop 100 is compatible with other Mapei products from the Mapegrout and Elastocolor ranges.

• Fast-drying fine repair mortar
• Suitable for rapid finishing of facings
• Ideal for small repairs
• Compatible with other Mapei products

Application examples:

• Evening out surface imperfections in prefabricated concrete, such as interlocking panels, beams and pillars
• Finishing of cement renders or lime and cement mortar before painting with Elastocolor range of products
• Small repairs to precast concrete sections damaged while being moved
• Rapid finishing of concrete facings repaired with products of the Mapegrout range

Because of its high synthetic resin content, Planitop 100 has excellent adhesion to all cement-based surfaces and forms a compact and mechanically strong layer after hardening (1 to 1.5 hours at +20°C).

Application

Preparation of the substrate

Substrates must be sound and free of dust, loose materials, and form-release agents. Reinforcing bars must have rust removed and then be treated with Mapei Mapefer or Mapei Mapefer 1K. Saturate concrete or other porous materials with water. Wait for the excess water to evaporate before applying Planitop 100. To facilitate the elimination of free water, use compressed air or a sponge. In no case can the mortar be applied on substrates that have a film of surface water.

Preparing the mix

Pour a 25 kg bag of Planitop 100 into a container filled with 6.5 - 6.75 litres of clean water while mixing continuously with a low speed electric mixer until a homogeneous, lump-free mix is obtained. N.B. After mixing with water, Planitop 100 is workable for 20 to 30 minutes at +20°C. Prepare only as much Planitop 100 as can be used during that time.

Applying the mix

Apply Planitop 100 with a flat trowel in a maximum thickness of 3 mm. To facilitate smoothing, several coats can be applied one after the other as soon as the previous one is sufficiently dry. Alternately, a few minutes after application a float sponge may be used for finishing; in this case the surface finish will be very similar to that of a fine grain plaster.
