and free of loose particles
The surface must be clean
Free of dirt

If you are not sure about the surface base layer
If in doubt, please do a small sample test first
Preparation for base layer treatment
Mechanical methods such as sandblasting or grinding must be used to completely remove cement laitance and cement slurry with insufficient strength. Oil stain
Until an open base with good surface strength and roughness is obtained, the soft concrete must be removed
The loose concrete surface voids
The pores must be fully exposed
Patch and fill the concrete The voids/
pores on the surface should be treated with appropriate Sika special systems
and
Concrete base treatment
Leveling is to obtain a smooth and beautiful surface
It is difficult to treat It is recommended to grind the raised points
All dust
Loose laitance must be completely removed before construction
Steel brush and vacuum can be used

Before construction
Check and confirm the moisture content and dew point of the base layer
If the moisture content of the base layer

as primer
Continuously apply

It can be applied twice if necessary
As leveling mortar
Rough concrete must be leveled first
Use the leveling mortar to use a rubber roller or scraper to scrape it to the required thicknessbr/> As the middle Layer
Pour
onto the base layer, spread it evenly with a sawtooth scraper, and immediately use a defoaming roller to roll it in both horizontal and vertical directions to ensure a uniform thickness. If you need to throw sand, you need to throw it lightly after

Repair
While the adhesive layer is still sticky , use a horizontal plate and pressure strip to find the level
After a short waiting time, use a scraper or a polisher with a Teflon surface to compact (

Equipment/
Tools Cleaning
Tools and equipment should be cleaned immediately after use
Cleaning
Those that have hardened/
cured must be removed mechanically
Remarks on construction restrictions
Cannot be used On base concrete with obvious rising moisture
The construction has just been completed
Moisture must be strictly prohibited
Condensation and water for at least
hours
Avoid contamination of the completed work. Primer
The mortar layer cannot be constructed in places that are often exposed to water vapor
Unless the base layer has been sealed
Choose the most suitable aggregate in actual operation
Outdoor construction should be done when the temperature drops. Construction, if the construction is done when the temperature rises, needle holes will occur.
