Easy-leveling mixture for floor screed inside and outside buildings (layer thickness from 10 to 40 mm), surface preparation for laying tiles, carpet, linoleum or layers, self-leveling. It is used for repairing cement floor coverings, concrete substrates.
The base must be seasoned (at least 28 days), non-water-absorbing, rigid, durable (strength at least, megapascal: under compression – 20 at break – 1,5) and resistant to deformation from external loads. The covering of ceramic and stone tiles, as well as wood, polymer or asphalt, is removed. The substrate is cleaned of sagging, areas of weak strength and substances that reduce adhesion (fats, oils, paints, etc.). Remove the weak surface layer with a sander, sandblaster or steel brush. The resulting dust is removed with a vacuum cleaner. The cleaned surface with high water absorption is impregnated with SCANMIX primer and dried until the gloss disappears on the surface, but not less than 4 hours. Insufficient quality of preparatory work can lead to delamination or cracking of the laid layer.
TOOL FOR WORK: Containers made of stainless materials, a low-torque drill with a mixing attachment, leveling beacons, a 2-3 meter ruler, stainless spatulas for leveling, a vibrating screed for compaction.
The mixture is slowly poured into a container with a calculated amount of water at a temperature of +15 … 20 ° C and simultaneously stirred until a homogeneous mass is obtained. If the mixture thickens within 1 hour from the moment of mixing, its mobility can be restored by repeated mixing without adding water.
The solutions are evenly distributed over the surface using shovels or special rakes, after which they are compacted and smoothed with a vibrator, a power tool(with a smoothing disc, a machine with a smoothing propeller) or manually – with shovels, trowels, tapping with stroking or in another way, until complete compaction (the surface begins to shine).
In preparing the foundation and the works, be guided by the requirements Building regulations 3.04.01-87 and State Building Norms of Ukraine V.2.6 -22 -2001.
It is necessary to ensure the isolation of the nested screed from vertical surfaces by installing foam or foam inserts with a thickness of 3 … 5 mm along the perimeter of walls, columns, foundations, etc. In screeds with a thickness of more than 40 mm, in order to save mortar and protect against the occurrence of shrinkage cracks, it is recommended to add a large (no more than half the layer thickness) aggregate (expanded clay, crushed stone (granite or from solid bricks)), in an amount not exceeding the initial volume of the mortar mixture. At the same time, the strength of the screed is reduced accordingly.
Perform work at an air and base temperature of +5 … 30 ° C and a relative air humidity of at least 60%. Protect the screed from drying out by eliminating drafts or cover with a waterproof film. After hardening, until the desired strength is reached, the screed should be kept moist.
The manufacturer is not responsible for the incorrect use of the material, as well as its use for purposes and conditions not provided for in the instructions.
Do not pour mortar and water into sewer pipes after work. It is advisable to wear rubber gloves. Avoid contact of the solution with the skin or eyes. In case of contact with the skin or eyes, rinse thoroughly with water, since the mixture contains cement, which, when mixed with water, forms an alkaline medium.
In dry space and on pallets, in factory packaging: 12 months from the date of issue indicated on the package.
The dry mixture is packed in paper bags of 25 kg.
