Drew has suggested an alternative water based sealant by Adseal. What is the differenence to Invisiseal?
The simplest way to describe, the Invisiseal is just a stain guard, it only stops liquids from soaking in thats it, whereas the water based sealer as well as stopping liquids from soaking in applies a coating to the surface so offers protection against wear and so extends the life of the paving.
