The Importance of Water Retention of HPMC
April 24th 2024
Construction mortars include plastering mortar, masonry mortar, tile adhesive, grout, and floor mortar. When applied to the base surface with high water absorption, good water retention is very important for building mortar.HPMC will have an excellent performance in dry mix mortar. The opening time of building mortar refers to the ability of the mortar to maintain its initial workability for a certain period of time after mixing, even if it is applied to a porous (high water absorption) base surface. Products with good water retention lose very little water, and this small part of the water is also absorbed by the base surface.
The key dry mix applications:
Dry mortar mixtures are used in many different applications in the construction of a building. Some of these applications are universal and some others are specific to certain regions or countries.
a. Cement-based tile adhesives
b. Renders and plasters based on gypsum or cement
c. External thermal insulation composite systems (ETICS)
d. Tile grouts
e. Self-leveling underlayments and screeds
f. Repair mortars
g. Brick-laying masonry mortars
h. Cementitious waterproofing
How to make mortar mix?
When making tile with a mortar mix, choose a thin mortar, also known as dry mortar, dry adhesive mortar, or simply “thin mortar”. The mortar forms a strong adhesive in a thin layer, making it the best choice for tiles. Mixing thinset is comparable to mixing standard mortar.
The amount of water and mix required for the job is determined by the manufacturer’s recommendations. The standard mortar mixing ratio is one part mixed with four parts water.
Pour the water into the mixing container.
Add the mixture to the container.
Stir for approximately five minutes.
Allow the thin mixture to stand for 10 minutes.
Stir for another five minutes to check the consistency. If the tile mortar mixture has a peanut butter appearance and is of sufficient thickness, it is ready for use.
