Mapei Planitop 100 – Quick-Setting Fine Mortar for Concrete and Render Repair

Mapei Planitop 100 is a quick-setting, light-grey cementitious fine mortar designed for repairing, smoothing and finishing concrete and render surfaces. Its fine-grained formulation is suitable for filling small surface imperfections, porous areas, chipped edges and minor defects in cement-based substrates.

Suitable for internal and external applications, Planitop 100 can be used on precast concrete elements, cement renders, lime-cement mortar and concrete facings. It is also suitable for finishing concrete surfaces repaired using products from the Mapegrout range.

Key Features and Benefits

• Quick-setting: Provides a workable repair and finishing mortar with a pot life of approximately 20–30 minutes at +20°C.
• Fine-grained formulation: Maximum aggregate size of 0.2mm for smooth surface finishing.
• Concrete repair: Suitable for filling small imperfections, porous areas and chipped cement-based surfaces.
• High adhesion: Designed to bond to suitably prepared concrete and cementitious substrates.
• Internal and external use: Suitable for a range of concrete and render finishing applications.
• Versatile application: Can be used for thin finishing coats and, with the specified additional sand, certain thicker localised repairs.
• 25kg packaging: Supplied in pre-packed bags.

Applications

• Repairing and finishing porous or chipped cement-based surfaces.
• Levelling surface imperfections in precast concrete panels, beams and pillars.
• Finishing cement renders and lime-cement mortar before painting with compatible coatings, including the Elastocolor range.
• Small repairs to precast concrete elements damaged during transportation or handling.
• Finishing concrete facings repaired with Mapegrout products.
• Filling superficial defects, honeycombing and surface irregularities in concrete.

Application Thickness

Planitop 100 can be used in different ways depending on the required repair thickness:

• Fine finishing application: 1–3mm when used neat.
• Thicker localised repairs: 3–30mm when mixed with the specified additional sand.
• Sand addition: Up to 30% sand with a maximum aggregate size of 2mm, following the manufacturer's instructions.

Do not use Planitop 100 neat for large or deep concrete repairs. For substantial concrete restoration work, use a suitable Mapegrout repair mortar.

Mixing and Application

For fine finishing coats, pour approximately 6.5–6.75 litres of clean water into a suitable mixing container. Slowly add one 25kg bag of Planitop 100 while mixing continuously with a low-speed mechanical mixer until a smooth, homogeneous and lump-free mortar is obtained.

Apply using a flat trowel, keeping the thickness within the recommended limits. Several coats can be applied one after another once the previous coat is sufficiently dry. Alternatively, a few minutes after application, a sponge float can be used to achieve a fine-grained plaster-like finish.

For thicker localised repairs, follow the manufacturer's separate mixing instructions for adding up to 30% sand with a maximum grain size of 2mm.

Important Application Recommendations

• Do not use for large-area concrete repairs; use an appropriate Mapegrout product.
• Do not add lime, cement or gypsum to the mixture.
• Do not add additional water once the mortar has started to set.
• Do not apply at temperatures below +5°C or above +35°C.
• Concrete and porous substrates should be saturated with water before application, allowing excess water to evaporate.
• Do not apply to substrates with a film of standing surface water.
• Protect freshly applied mortar from rapid drying, particularly in hot or windy conditions.

Frequently Asked Questions

What is Mapei Planitop 100 used for?

Planitop 100 is used for small repairs, smoothing and finishing concrete and cement-based render surfaces. Typical applications include precast concrete panels, beams, pillars, chipped surfaces and minor surface imperfections.

How much water is needed for a 25kg bag?

Approximately 6.5–6.75 litres of clean water per 25kg bag when preparing the standard fine finishing mix.

How thick can Planitop 100 be applied?

When used neat, it can be applied at 1–3mm thickness. For localised repairs between 3mm and 30mm, the manufacturer specifies adding up to 30% sand with a maximum grain size of 2mm.

What is the pot life of Planitop 100?

Its approximate pot life is 20–30 minutes at +20°C. Only prepare the quantity that can be applied within this working time.

What is the coverage of Planitop 100?

When used neat, consumption is approximately 1.3kg/m² per mm of thickness. Actual coverage depends on the substrate and repair depth.

Can Planitop 100 be used externally?

Yes. It is suitable for internal and external concrete and render repair and finishing applications, provided the substrate is correctly prepared and application conditions meet the manufacturer's requirements.

Can Planitop 100 be used for large concrete repairs?

Mapei recommends using products from the Mapegrout range for large concrete repairs. Planitop 100 is intended primarily for fine finishing and smaller localised repairs.
