Laminate countertops are generally water-resistant to some extent, but they are not completely waterproof.
Laminate countertops can withstand occasional spills and splashes, and they are relatively easy to clean and maintain. However prolonged exposure to standing water or excessive moisture can lead to damage. Over time, water can seep into the seams, edges, or any damaged areas of the laminate, causing it to swell or warp.
To maintain the water resistance of your laminate countertop, it's essential to:
Wipe up spills promptly to prevent moisture from penetrating the seams and mostly edges.
Use a cutting board and avoid cutting directly on the laminate surface to prevent nicks and cuts.
Seal the edges of the countertop, especially near sinks and other areas prone to water exposure, with silicone caulk to provide extra protection.
Overall, laminate countertops can offer decent water resistance and years of long term use for most kitchen and bathroom applications if properly maintained
