Mapei Planitop 210 is a one part, water-repellent, cementitious skimming mortar with a fine, natural finish for internal and external concrete, lime based render, old quartz paint and plastic coatings.

Mapei Planitop 210 is a one-component, water-repellent, normal-hardening, fine-grained, powdered cementitious skimming mortar available in grey and white, made from special, high-strength binders, selected aggregates, special additives and synthetic polymers. When Planitop 210 is mixed with just water, its special composition forms highly-adhesive mortar with high plasticity, which makes it easier to spread with a smooth trowel and facilitates finishing operations with a metal or sponge float.

Best Uses

Mapei Planitop 210 is ideal as a finegrained, natural-finish skim coat on internal and external concrete, cementitious and lime-mortar render, old quartz paint and scratch-effect plastic coatings.

Planitop 210 may be applied at a maximum thickness of 3 mm per coat. Apply thicker layers up to a maximum of 6 mm in two coats, and place Mapenet 150 alkaline-resistant glass fibre mesh (in conformity to ETAG 004 guidelines) with a mesh size of 4 x 4.5 mm between the first and second coat. Mapenet 150 must also be used when the surface to be skimmed is made up of different types of material. In good weather, apply coloured finishing products from the Silexcolor, Silancolor, Quarzolite, Elastocolor, Colorite or Dursilite ranges 1 week after applying Planitop 210. The latter product may be used for decorating internal or external surfaces
as long as they are partially covered and protected from direct exposure to the sun and rain.

Planitop 210 conforms to the principles defined in 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.

Some application examples

• Levelling and finishing masonry and concrete walls, cementitious and lime-cement render before painting.
• Smoothing the surface of walls, including walls painted with washable acrylic or quartz-based paint, plastic coating, etc., as long as they are sound, clean and well-bonded.
• Skimming plasterboard panels (if gypsum-based skimming mortar has been applied between the panels, treat beforehand with Mapei Primer G).
• Skimming mineral wood panels (such as Mapei Eraclit®).

Application

Surfaces must be perfectly clean and solid. Old paintwork must be sound and well bonded to the substrate. We recommend, therefore, that substrates are prepared
carefully by mechanically removing all loose or detached areas of existing finish, and then cleaning the surface where the mortar is to be applied with water to remove any traces of dust which could impede adhesion. Before applying Planitop 210, wait until the film of surface water has evaporated or dry it off with compressed air or dry rags. Absorbent substrates, such as render and concrete, must be dampened beforehand with water, while old paintwork must be perfectly dry when applying Planitop 210.

If the substrate is still powdery after cleaning, which indicates a lack of surface cohesion, apply a primer from the MAPEI range to consolidate the surface (please refer to our Technical Services Department).

Spread the mortar on the surface prepared as described above in coats up to 3 mm thick using a smooth metal trowel. Finish off the surface of Planitop 210 using
the same trowel or a traditional damp sponge float a few minutes after application. During hot or windy weather, or in particularly hot areas, spray water on the
surface of the smoothing compound when it starts to set (that is, when it may be pressed lightly without leaving fingerprints) and over the next few days when the
mortar has completely hardened, to avoid quick drying and hygrometric shrinkage which may cause cracks to form.

Pour 5.25-6.0 litres of water into a suitable clean container and slowly add the contents of a 25 kg bag of Planitop 210 while mixing. Mix thoroughly for several minutes, making sure that there are no traces of powder stuck to the sides or bottom of the container. Keep mixing until thoroughly blended (completely lump-free). A mechanical mixer at low speed is recommended for this operation to prevent entraining too much air into the mix. Avoid mixing the product manually.
