"I have used this and many other primers for over 32 years now. Am just ordering some more from SF. This is really good stuff and does the job intended. Great adhesion and reliability as you would expect from a big brand name.
Those of you who STILL use pva....DON'T! It is not meant for tiling and will lead to failures. I am even unhappy when plasterers use it over paint to finish a wall ready for tiling. Who said the paint was secure? Remove paint when tiling whenever possible. Yes it is a nightmare sometimes but, is worth it. Just telling you this as no primer including 'G' is not made of magic stuff, it will not stop tile coming loose over painted walls.
Once the walls/floors are ready, use this stuff. Primer G won't let you down."
"Slightly easier than making a PVA dilution, although somewhat more expensive. Seems to work just as well, so if time is really important, then this could be the answer. Otherwise stick with the traditional method."
