One more time, just for those with an inflated opinion of themselves and their opinion…
Youve used “MrFixit” product, maybe twice… great for you ????????
And “Flintcoat” !!
WOW, you are awesome.
Why don’t you tell me how many 20kg drums of “Ardex WPM155” you’ve used ?
I have used HUNDREDS, and counting its predecessors it would be one thousand plus 20kg units over my career.
I an an active professional ceramic tiler of 40 years, my then state based waterproofing licence was number 016.
The product I recommended as my second choice solution to the OP’s problem “Ardex WPM300” is a product I’ve only used once, as in my line of work it’s a specialty product.
I’ve read many of your posts and on many subjects you are very knowledgeable but I dislike your self presumed superiority to everyone else.
Have a nice day ????????
