Reduce the Noise Caused by RV Sinks

Aluminum and stainless steel RV sinks can be a bit noisy, especially when confined in a small kitchen area. Tinging noises can come from dropping things in the sink and movement/vibrations while driving. These types of sinks also do not maintain temperatures for both hot and cold items very long.

Some more modern RV sinks will add some sort of padding to the bottom before installation, however, that is only in a small area and does not reduce all of the noise. This padding may help reduce the noise when silverware or a cup are placed in the sink, but not when larger items are set in it or when the RV is in motion.

This is why we suggest spraying the bottom of RV sinks with some type of sealant or spray on insulation. Suggested products to spray RV sinks with include Rust-O-Leum’s Leak Seal, Performex’s Plastic Dip or Dap’s Daptex Plus. The one you choose will depend upon your preference.

When spraying RV sinks either remove the sink and spray in an open, well ventilated area or use a breathing mask and goggles if spraying after the sink has been installed. When spraying use an even sweeping motion covering the surface area. If necessary, use a piece of cardboard to contain any over-spraying and protect surrounding objects. If using Daptex Plus or similar product, you will also need a spatula or a spreader to help even out the insulation.

Once dry, your final product will reveal an RV sink that is not as noisy when using it or from the vibration sounds aluminum and steel can make while the RV is in motion.
