PLANEX HR MAXI Rapid-drying, moisture resistant, self-levelling smoothing compound for layers 3 to 40 mm thick
CLASSIFICATION ACCORDING TO EN 13813 Smoothing layers of Planex HR Maxi applied according to the specifications in this Technical Data Sheet are classified as CT-C30-F6-A1FL in compliance with EN 13813 Standards.
WHERE TO USE Planex HR Maxi is suitable for internal and external applications and is used to level off new and existing substrates and remove differences in thickness from 3 to 40 mm to make them suitable for laying all types of floor coverings, including resilient, textile and ceramic tiling. Planex HR Maxi is particularly recommended for use in areas where high resistance to static and dynamic loads is required. Thanks to its special formulation and good resistance to moisture, Planex HR Maxi may also be used for external applications or on substrates that are not completely dry or which have a high level of residual moisture.
Some application examples
· Smoothing over concrete floors and cementitious screeds made from Mapecem, Mapecem Pronto or Topcem Pronto. · Smoothing over heated floors. • Smoothing over existing concrete, terrazzo, ceramic, natural stone and magnesite floors. · Smoothing over concrete and cementitious-based substrates before bonding non-welded resilient floor tiles with reactive adhesive in areas that need to be washed or rinsed frequently. · Smoothing over concrete substrates with rising damp before placing PVC isolating sheets on which resilient flooring for sporting and non-sporting use is to be installed.
TECHNICAL CHARACTERISTICS Planex HR Maxi is a grey coloured powder made from special rapid-hydrating and rapid-setting cement, selected silica sand, resins and special admixtures according to a formulation developed in the MAPEI research laboratories. When Planex HR Maxi is mixed with water, it forms a rapid-drying, free-flowing, self-levelling mortar with good workability that adheres very strongly to the substrate. Planex HR Maxi is applied in layers from 3 to 40 mm thick per layer. It does not shrink or crack and reaches a high level of compressive and flexural strength and resistance to indentation and abrasion. Planex HR Maxi dries very quickly: for example, ceramic may be bonded after 3 hours and resilient and textile floor covering may be bonded after 24-72 hours, depending on the smoothing layer thickness.
RECOMMENDATIONS · Do not add water to the mix once it starts to set. · Do not add lime, cement or gypsum to the mix. · Do not use Planex HR Maxi on metal, wood that is not highly stable, rubber, PVC or linoleum. · Do not use Planex HR Maxi if the temperature is lower than +5°C.
