Product Description

Mapei Mapetherm Flex RP is a cement free, fibre-reinforced, lightweight, elastic, skimming paste and base coat. Resistant to biological agents for internal and external use. Colourable and available in two texture grades (0.5 mm and 1.5 mm).

Mapetherm Flex RP is an organic skimming base coat characterised by high elasticity made from acrylic resins in water dispersion, selected fillers, glass micro-spheres and polypropylene fibres. It also contains admixtures that make it resistant to biological agents. Unlike traditional cementitious based smoothing and levelling compounds Mapetherm Flex RP does not need to be fully cured and there is no need to use a primer before applying the final finish, thereby reducing the time to complete work considerably.

Best Uses

Mapei Mapetherm Flex RP is ideal as a reinforced skim coat on insulating panels and thermal insulation systems. It is also suitable for renovating damaged /
deteriorated insulating systems, and repairing cracked walls on all types of buildings, including painted walls. Mapei Mapetherm Flex RP is also suitable for repairing render to even out surface defects.

Mapetherm Flex RP is particularly recommended for protecting critical areas such as wainscots, communal areas in apartment buildings and areas open to the public exposed to impact and stresses. Mapetherm Flex RP, in the 0.5 mm version, is ideal for use on surfaces where a smooth even finish is required, including on insulation systems and may be used to level internal walls that require a smooth, elastic finish.

Mapetherm Flex RP adheres perfectly to all types of insulating panels, skimming mortars, traditional render and old, well-adhered paintwork. Thanks to its special composition it also provides excellent resistance to impact loads: used in the main Mapetherm systems in combination with 1.2 mm thick layers of plaster; it passes 15 Joule impact tests. Mapetherm Flex RP may be tinted using the ColorMap® automatic colouring system. When applied in a colour similar to that of the finishing coat, apart from reducing the number of coats required, it hides imperfections in the substrate and helps form an even, uniform finish.

Application

Mapetherm Flex RP is supplied ready to use; 1-2% of water may be added if the product is too thick. Apply the product with a stainless steel trowel making sure the product is applied in an even coat. Then go over the surface with a plastic float to obtain an even finish.

Skim coats on insulating panels
Once the adhesive is completely dry, spread an even levelling coat of Mapetherm Flex RP on the surface and embed Mapetherm Net alkali-resistant glass fibre mesh in the product. Press Mapetherm Net down into the product while still wet with a smooth trowel, overlapping the edges of the mesh by 5-10 cm. After 12-24 hours apply a second layer of Mapetherm Flex RP skimming paste to form a compact, even surface suitable for the final coat which must be applied after 24-48 hours,
depending on the level of surrounding humidity and temperature, and in all cases only when the previous coat is completely dry. No primer is required.

Reinforced skim coats on façades
Remove all traces of oil and grease from the surface and any parts which are not well bonded. Areas patched up with repair mortar must be well-cured, perfectly clean and cohesive. The substrate must be dry. Prepare the substrate by applying a coat of Malech. Wait 12-24 hours, apply an even layer of Mapetherm Flex RP and press Mapetherm Net A.R glass fibre mesh into the mortar, overlapping the edges of the mesh. After 12-24 hours apply the second levelling coat. After a further 24-48 hours, depending on the level of surrounding humidity and temperature, and in all cases only when the previous coat is completely dry, plaster the surface or apply two coats of paint. No primer is required.

Repairs to damaged/deteriorated insulating systems
Make sure the old insulating system is bonded to the substrate. Do not apply Mapetherm Flex RP on damp substrates. Remove all traces of oil and grease from
the surface and any parts which are not well adhered. Prepare the substrate by applying a coat of Malech. Wait 12-24 hours, apply an even layer of Mapetherm Flex RP over the old cladding and press Mapetherm Net A.R glass fibre mesh into the mortar. Press the Mapetherm Net down into the product while still wet with a smooth trowel, overlapping the edges of the mesh by 5-10 cm. After 12-24 hours apply a second levelling coat of Mapetherm Flex RP to form a compact, even surface suitable for the final coating product, which must be applied after waiting at least 24-48 hours, depending on the level of surrounding humidity and temperature, and in all cases only when the previous coat is completely dry. No primer is required.

Mapetherm Flex RP 0.5 mm
Apply the product with a stainless steel trowel making sure the product is applied in an even coat. Then it may be worked with a sponge float while it is drying to
create a fine textured rustic effect. When used to skim thermal insulation system with a natural finish. After preparing the substrate as specified with Mapetherm Flex RP 1.5 mm reinforced with Mapetherm Net mesh, apply one or two layers of Mapetherm Flex RP 0.5 mm to obtain a smoother finish than with traditional textured plaster; wait until the first layer is completely dry before applying the second one (12-24 hours).

Use Mapetherm Flex RP 0.5 mm
in a similar colour to that of the final finish, which may only be applied once Mapetherm Flex RP 0.5 mm is completely dry (24-48 hours depending on surrounding
temperature and level of humidity).

Skim coats on internal walls
The substrate must be dry with no traces of dust or dirt. If necessary apply by brush, roller or by spray one coat of suitably diluted Malech, according to the substrate
absorbency. Apply two coats of Mapetherm Flex RP after at least 12-24 hours and finish off the surface with a sponge float. After a further 24-48 hours, depending on the level of humidity and surrounding temperature, and in all cases only when the previous coat is completely dry, apply two coats of interior paint such as Dursilite, Dursilite Matt or Colorite Matt. If required, the levelling coat may be reinforced with Elastocolor Net. No primer is required.
