MASTERSEAL 582 | Outdoor floor waterproofing

Specifications

Surface preparation

• The base must be dry, free from defects, mostly even, clean and finely porous, free from shells, voids, cracks, dust, tar, bitumen, old paint and other factors that impair adhesion;

• Wood and metal inclusions should be removed, and active leaks should be repaired with  MasterSeal 591 or other methods;

• Cavities and sinks must be filled with mixtures from the MasterEmaco series;

• At vertical and horizontal corners, rounding with a radius of at least 4 cm should be applied;

•  If the material, after being applied to the surface, begins to quickly lose water. This means that the surface is not sufficiently moistened; 

• For application in conditions of high temperature or in windy weather, it is possible to increase the dosage of water by 10%.

Mixing

• Add liquid part B ( MasterSeal 600 ) and the recommended amount of water to a clean mixing container, slowly add part A ( MasterSeal 582 part A) and mix at low speed 400-600 rpm, for 3-5 minutes, until a homogeneous mixture consistency;

•  Let the mixture mature for 3-5 minutes, then stir again for 30 seconds. After that, the mixture is ready for use.

Application

• The prepared mortar is applied by Thoro Brush with a brush or spatula in 2 or 3 layers in perpendicular fusing one to the other;

• The time interval between layers depends on the application conditions.

Consumption

• 1st layer - 1.3 kg / m2.

• 2nd layer - 1.2 kg / m2.

• 3rd layer - 1.2 kg / m2.

Important aspects when applying

• Air temperature and substrate temperature must be at least 5 ºС or not more than 25 ºС;

• Do not use MasterSeal 582 in the rain or if it is possible to rain;

• MasterSeal 582 applied at +23°C gains mechanical strength after 2 days, becomes waterproof after 7 days and gains final strength after 14 days;

• The coating must be protected from direct sunlight, wind, frost or rain for 24 hours;

• The application time of systems based on cement and bitumen emulsions depends on the temperature and relative humidity of the air;

• At low temperatures, the reaction slows down, which increases the working time and setting time;

• High temperature speeds up the reaction and the times mentioned above are shortened; 

• In order for the material to harden, the temperatures of the material, base and air cannot be less than the minimum permitted temperatures;

• Areas that are not yet fully cured should not come into contact with water;

• The film thickness of each coating layer should not exceed 1.3mm;

• Do not use MasterSeal 582 as a coating in pedestrian areas;

• The coating here must be protected with a screed or ceramic tiles; 

• Apply, for laying tiles, materials of the MasterTile series.

• Set weighing 27kg;

• Part A - 25kg bag;

• Part B - canister 2kg + 5-5.5 liters of water.

Storage

• Store in original unopened packaging in cool and dry conditions, protected from frost;

•  For short-term storage, a maximum of 3 pallets can be stacked one on top of the other;

• Do not approach storage facilities during a fire;

• Store products in well-ventilated areas;

• During work, work clothes, protective gloves, goggles and a mask should be used in accordance with health and safety regulations;

• Since uncured materials have an irritating effect, contact of the components with the skin and eyes should not be allowed, and in case of contact, rinse with plenty of water;

• If swallowed, seek medical attention immediately;

• It is forbidden to bring food and drink to the construction site where the product is used;
