This is how to waterproof the easy way.
A nice clean wall to get started.
Prime the wall and Floor liberally with an approved primer. One that is recommended on the waterproofing materials.
Apply the first coat of Waterproofing.
You can use a brush or roller. Cover approximately 120 mm up the wall and across the floor.
This is ‘Backer Rod’ used to fill the joint between the wall and floor. It’s made from foam and is soft and flexible.
It is recommended to use one with a diameter of 10 mm or more. Any size up to about 15 mm will be fine.
Push the ‘Backer Rod’ into the still wet first coat of waterproofing. Making sure that the backing rod stays in place once you let go of it.
Now you need to cover the backing rod with an appropriate type of cloth or fibreglass bandage. The bandage should be about 200 mm wide and not too long to make it easier to apply. Centre it over the backing rod and prod and poke it until it forms to the shape of the backing rod. This will make the joint flexible
Once you have covered the backing rod. Continue painting the entire area again and make sure you completely cover the bandage. If need be, a third coat can applied after the second coat has completely dried. This may take overnight to be completely dry.
This is what the waterproofing should look like.
The backing rod covered with a bandage and then one or two coats more of waterproofing.
Make sure you check the waterproofing for any holes. Even a pin hole will be enough for the waterproofing not to work.
The best waterproofing advice is
‘Buy the right Materials’. Ask or read the label to see if the product you are purchasing will do the job. Use the same brand of materials wherever you can. Use a primer that is recommended on the waterproofing container. The backing rod and Bandage have little effect on performance. They don’t necessarily need to match with the waterproofing manufacturer. As long as the waterproofing won’t melt or affect the backing rod you should be fine.
Cut the bandage into lengths that are easy to handle. Double up in corners as well to provide more strength.
