What is Spray Waterproofing?

Last Updated Nov 17, 2011 · Written by Jaclyn Fitzgerald

If there is a chance that an area of your home – internal or external – is going to be exposed to water, it will need to be waterproofed. There are a number of ways that you can do this but one that is becoming more and more popular is spray waterproofing.  Not sure what this is?  Here’s what you need to know.  If you have any further questions or you’d like to see if spray waterproofing is suitable for your job, have a chat with your local waterproofing professional. They’ll be only too happy to help.

About Spray Waterproofing

Spray waterproofing is simply a method of applying a liquid waterproofing agent to a surface.  It is sprayed on by an experienced professional using a spray gun of some sort.  The waterproofing agent goes on liquid but it dries into a flexible, impermeable membrane that water simply cannot get through.  There are no joins and no gaps that are potential weak points if the waterproofing agent is sprayed on correctly.

Spray waterproofing can be applied to just about any surface as it bonds very well. This includes concrete, masonry, stone, fibre cement, fibreglass, steel, tiles, and so on.  The bondability of spray waterproofing means that you don’t have to worry about it coming off or anything like that.  Spray on waterproofing is becoming more and more popular not only because it is so effective but because it is so easy to apply. You don’t have to lug around heavy or unwieldy membranes, or worry about the membrane getting damaged before it is put in place.  It is also very fast to apply.

Why Is Waterproofing Necessary?

Waterproofing is absolutely essential if there is a chance that your surface will be exposed to water in any way.  Common areas that need to be waterproofed include pools, roofs, balconies, the inside of tanks, bathrooms, and floors.  If your surface is not waterproofed, water will soak through, first damaging the surface itself, then the substrate, and finally it will go deep enough to damage the structure of your building.  If this happens, it can be very difficult and expensive to fix.  Areas exposed to moisture constantly without getting the chance to dry out can also harbour mould and mildew which is not only unsightly but a real health hazard.
