These two pavers are held together with a cable tie. The gap between them is one mm. Water can not pass through the small crack. We can move the stones against each other and the water will not pass through.
When we pull the blocks apart, to give a gap of 4mm the water passes through.
This coat of SWG has created a crack bridging ability of 4mm. Remarkable!
This Victorian stone wall is built from Limestone with a sand/ cement pointing. When we spray the wall with water you can see that the stone and pointing absorbs water.
It is this easy to spray an SWG water repellent coating onto the lower half of this wall.
This video shows that the lower half of the wall is not absorbing water. The water is beading down the wall.
