When using rapid repair mortar for concrete pavements, here are some points to consider
Surface Preparation: Ensure the repair area is clean and free of oil, dust, and loose materials.
Moistening the Surface: Thoroughly moisten the concrete surface before applying the mortar to enhance bonding strength.
Pre-application: The ground should be in a damp but not wet condition when applying the mortar. This prevents water-cement imbalances that could affect the outcome and strength.
Mixing Ratio: Follow the product instructions strictly for mixing to ensure the quality of the mortar.
Application Temperature: Avoid applying the mortar under extreme temperature conditions. Generally, the recommended application temperature range is between 5°C and 30°C.

To improve the bonding effect of rapid repair mortar for concrete pavements, consider the following steps
Use of Primer: Before applying the mortar and after wetting the repair area, apply a layer of primer.
Proper Moistening: Keep the base surface moist but free of standing water.
Surface Preparation: If the ground has severe dusting or sand problems, you can use a milling machine to roughen the surface and expose a hard base, or treat it with a hardener or other complementary products before applying the mortar.

The reasons for cracking in self-leveling cement include:
Poor Base Conditions: Severe dusting, low base strength, existing cracks, or hollow sounds in the base that have not been addressed can lead to cracking under heavy loads after construction.
Incorrect Application Techniques: If self-leveling cement is not applied according to proper techniques, such as uneven thickness or too rapid drying, it may also result in cracking.
High Moisture and Contaminants: Excessive moisture, oil, dirt, or other contaminants on the construction surface can affect the adhesion between the self-leveling cement and the base, leading to delamination and cracking.
Improper Use of Primer: Incorrect use of primer can cause rapid surface water loss, leading to excessive shrinkage and cracking of the cement.

Can you supply the relevant documentation?
Uneven Application: During construction, if the material is not spread in layers according to the specified method, this can lead to uneven distribution, with varying thicknesses, causing color differences.
Uneven Moisture Evaporation: During curing, if plastic film is used for coverage, it can result in uneven evaporation of moisture from the surface. Areas where the film touches the floor might appear lighter in color, while areas not in contact with the film retain their normal color.
Inconsistent Quality of Material: If the floor emery itself has inconsistent quality, with varying particle sizes or poor-quality pigments, it can result in non-uniform coloration.

How long does it take for Plug King to set?
The setting time for Plugging King (a type of quick-setting sealant) typically depends on the environmental temperature and humidity during application. Under normal conditions, it sets initially in 1-3 minutes and reaches final setting in 4-6 minutes in a spherical state.
