-
Principle of Hydrophobicity
The water beading test relies on the principle of hydrophobicity, where a properly sealed granite surface exhibits a high contact angle with water, causing droplets to form distinct beads rather than spreading out. The presence of well-defined water beads indicates a functioning sealant that effectively prevents liquid penetration. Conversely, if water spreads out and darkens the granite, the sealant has likely degraded, and the granite is absorbing moisture.
-
Test Procedure
The test procedure involves placing a few drops of water on the granite surface and observing their behavior. The water should bead up quickly, forming distinct spheres. If the water flattens out, spreads, or is absorbed into the granite within a few minutes, it signifies that the sealant is no longer providing adequate protection. This observation warrants consideration for resealing.
-
Frequency of Testing
The frequency of performing the water beading test depends on several factors, including the usage intensity of the granite surface and the type of sealant used. High-traffic areas or surfaces exposed to frequent spills should be tested more often, perhaps monthly or quarterly.
