Surface preparation
-
The substrate must be dry, free of defects, mostly even, clean and finely porous, free of pits, 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, roundings with a radius of at least 4 cm should be used.
-
The substrate must be thoroughly moistened before coating.
-
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 (MasterTile WP 667 part B) to a clean mixing container, slowly add part A (MasterTile WP 667 part A) and mix at low speed 400-600 rpm for 3-5 minutes until a homogeneous mixture is obtained .
-
Leave the mixture for 3-5 minutes to ripen, then stir again for 30 seconds.
-
After that, the mixture is ready for use.
-
MasterTile WP 667 Part A: 20 kg.
- Part B: 5 kg.
- The density of the mixture is: 1.90 kg/l.
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 - 1.4 kg / m2.
- 2nd layer - 1.2 kg / m2.
- 3rd layer - 1.0 kg/m2.
Important aspects when applying
-
The air temperature and the temperature of the base must be at least 5 ºС or not more than 25 ºС.
-
Do not use MasterTile WP 667 in the rain or if there is a chance of rain.
-
MasterTile WP 667 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 acrylic 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 reduced.
-
In order for the material to harden, the temperatures of the material, substrate 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 1.2mm.
-
Do not use MasterTile WP 667 as a pavement in pedestrian areas.
-
The coating must be protected with a screed ( based on the modifying additive MasterCast 125 ) or ceramic tiles.
-
Apply, for laying tiles, materials from the MasterTile series.
Cleaning tools
-
Clean tools and equipment with warm soapy water after use.
- Once MasterTile WP 667 has hardened, it can be mechanically removed from the surface.
