Water popping and how important is it?

When it comes to preparing Australian timber for Rubio Monocoat water popping is a necessity and we are going to tell you how and why.


What is water popping?

Water popping, also known as grain popping, does exactly that. It helps to pop the grain. By using clean water on a raw, unfinished timber surface you open up the closed or smooth wood grain. Timber naturally absorbs water (known as hygroscopic). When absorbing water the cells expand as the water evaporates and they remain open. This inturn causes the grain to raise and 'pop'.


Why should I water pop?

As suggested in the name Rubio Monocoat Oil Plus 2c is a single layer oil that penetrates the wood grain. In order to penetrate the wood grain needs to be open and if the grain is closed the oil will not penetrate easily. If you are using a pigmented oil then this may lead to less pigment being able to be absorbed into the grain causing a less intense colour.


How to water pop?

Its quite simple. Use a spray bottle filled with clean water and spray the entire project in-between each grit. Spray an even mist to the entire project, being careful not to leave any pooling of water. Once complete leave project to thoroughly dry, this should be fairly quick in Australian weather. Once dry move on to your next grit.


Water popping should take place between each sanding grit. It is a very important part of the process and should not be skipped.
