Several key "time" points for tile adhesive pasting!

What is the shelf life of tile adhesive?

In a cool and dry environment, the shelf life of unopened tile adhesive is 1 year. If the tile adhesive clumps, it means that its active ingredients have begun to react and should be discarded.

Mixing time of tile adhesive

Tile adhesive should be stirred with a low-speed mixer (500r/min). Add the powder into water and stir for 3-5 minutes to form a uniform adhesive slurry without powder lumps.

How long should I wait after mixing tile adhesive with water before using it?

Generally, we use a mixer to stir for 3-5 minutes, let it stand for about 5 minutes, and then stir it again before use.

There are two functions of standing here: one is to remove the air brought in during the stirring process, and the other is to allow the tile adhesive to fully mature, which is conducive to maximizing the bonding strength of the tile adhesive.

How long does it take to use the tile adhesive after mixing it?

The operable time of tile adhesive under standard conditions (20°C, 50% humidity) is about 3 hours. The actual operable time depends on the weather conditions. Generally, the operable time will be shorter in hot and windy weather. For example, in summer, the operable time of tile adhesive in southern regions will be shorter indoors. The stirred tile adhesive should be used up within 1 hour.

How long can tile adhesive be adjusted after tiling without affecting the bonding strength?

The time for tile pasting to be adjusted without affecting the bonding strength is generally within 30 minutes. If the adjustment is made after the adjustable time, the performance of the tile adhesive will be affected.

How long does it take for tile adhesive to dry and harden after tiling?

Refers to the time it takes for tile adhesive to solidify and harden after pasting. Usually the curing time of tile adhesive is 24 hours. In a low temperature and high humidity environment, the hydration reaction rate of cement-based products will slow down. In order to better lock in moisture, water-retaining agent is added to the tile adhesive, so the curing time will be extended accordingly. Therefore, the finished product should be well protected during construction in winter.

How long after the base is treated can the tiles be laid?

After the concrete surface is completed, it needs to be cured for 6 weeks before paving bricks; the newly plastered surface should be cured for at least 7 days before paving bricks. Old concrete and plastered surfaces can be cleaned with industrial detergents or degreasers, then rinsed with a high-pressure water tap, and the surface can be dried for 24 hours before paving bricks.
