Solutions to common problems in gypsum-based self-leveling mortar construction
1. What if there are cracks in the substrate?
For large cracks, make a "V" shaped groove, then clean it up and mix it with gypsum-based self-leveling HPMC dry powder and a small amount of water to achieve the consistency of plaster mortar to fill in the cracks and smooth them out.
2. If the ground is heavily sanded during the gypsum-based self-leveling process, what can be done to make sure the ground does not have porosity after construction?
The chromatic aberration of gypsum-based self-leveling is due to inconsistent control of the flow of self-leveling during construction, and excessive water addition will secrete on the surface, resulting in chromatic aberration after hardening. Under normal use conditions, with use, the color difference will become lighter.
3. What kind of flooring is suitable for gypsum-based self-leveling?
As long as the grassroots strength is not very bad, or can be reinforced to 1.0Mpa, you can carry out the construction of gypsum-based self-leveling, if the height difference is relatively large or the slope of the grassroots is obvious, then a sufficient thickness of gypsum-based self-levelling is required to level the subgrade, and if it exceeds 8mm, it is recommended to do it in stages!
Welldone Hydroxypropyl methyl cellulose HPMC for gypsum-based self-leveling will be your best choice.
