Wall Putty and Repair Mortar SGP500 (Gray)


Indoor and outdoor rendering and levelling mortar walls, floors and ceilings in thickness from 1 to 5 mm

 Fields of Application

—  Smoothening walls prior to restoration, ceramic tiles installation and painting.

—  Smoothening and filling hairy cracks on the surfaces of foamed cement, concrete, brick walls.

—  Repairing old, damaged renders, concrete up to 1-5 mm


—  High adhesion strength.

—  Smooth and solid surface.

—  Resistant to freeze and thaw.

—  Applicable up to 1-5 mm thickness.

—  Easily applicable.


—  Substrates must be compact, free of dust, loose parts and clean from oils, grease, paint or adhesive residues when SIMENTEK SGP500 can be applied to damp surfaces without cure time will be slightly prolonged.

—  It is advisable to wet highly absorbent substrates.

—  Pour 25 kg of SIMENTEK SGP500 into 5.5-6 litres of clean water slowly and mix to obtain a homogeneous paste free from lumps. (A low-speed mixer is recommended to mix).

—  Allow to stand for 5-10 minutes to mature. After remixing, the paste is ready for application.

—  Apply SIMENTEK SGP500 with a flat trowel with a firm pressure to ensure a good adhesion.

—  When applying on walls directly exposed to sun or wind, it is advisable to wet the surface of SIMENTEK SGP500 for the following 24 hours after application. For surfaces having ideal humidity and in ideal weather conditions, wait for 6 hours before tiling. Waiting time will be shorter in summer and longer in winter conditions.

—  The mortar should be used within 25 minutes. Unfavorable climatic conditions like high temperature, low humidity, wind may shorten this duration.

—  Dispose mortars of which pot life is expired.

—  Clean tools and hands with water, surfaces with a damp cloth.


— Since contains cement, irritating to eyes, respiratory system and skin. For further information refer to safety data sheet.
