Measure your sink
Sink measurements can vary up to 2%. Ensure you measure your sink before you begin cabinet and benchtop construction.
Use a flexible sealant
For under mount installation; any sealant used where the top of your fireclay sink meets the underside of a stone bench-top needs to be flexible (like mould resistant silicone), rather than rigid (like stone adhesive) to allow for any difference in expansion rates between the stone and the sink.
Once you have installed your sink, seal around the edges of your bench-top using a mould resistant silicon sealant such as Selleys Wet Area or Kitchen and Bathroom Silicon.
Ensure your plug is water tight
When installing the waste fitting/s it is important to use some silicone sealant between the metal waste flange (the part that you will see in the sink around the plug) and the glazed sink itself. This is to stop water from draining under the flange when the sink is filled. Please note that if surfaces are cleaned with a cloth dampened with Mineral Turps the silicone adheres very well. Also use the same cloth to clean up any excess silicone that squeezes out when the waste fitting is tightened. Ensure that the silicone is cleaned up BEFORE it dries.
Do not use glue on your sink
Please note: do not glue or use silicone on the underside of the sink. The sink should be installed sitting on a supporting shelf. There is no need to glue the sink down, as the glue will interfere with the natural contraction and expansion of the sink as it may lead to the sink being damaged. Gluing the sink to its base will void the warranty.
Optional: removal of the overflow bolt
If you don’t like the look of the bolt through the middle hole of the overflow section, you can silicone the overflow and gasket to the back of the sink, thread the bolt through, when silicone has dried remove the bolt and the overflow will stay in place.
