Moisture testing would generally be the responsibility of the main contractor but obviously in domestics there usually is not one. However if it were me being asked to tile the floor I would want my own piece of mind and test it myself. Testing with a hygrometer is very simple. You stick it the floor and leave it there for 48 to 72 hours and then read it. If it says below the % required by the adhesive ie 75 for cement 85 for gypsum then you are ok to tile. If it is above the numbers it is not ready. Drying depends heavily on site conditions. Warm and well ventillated is best. You can cotract out moisture teting for about £400 but you can buy a hygrometer for £30 so i know which i would do. Calibration is also important to make sure you read accurately. Further advice available on request.

I must be really thick or paranoid but I cant find suitable Hygrometers anywhere....all I find on flooring webshops is digital which I know is not good ?

Right todays job is sorting out a suitable floor grinder/scarifier/sander....I will have to visit hire shops in person as phone calls are proving useless.
Adhesive is 99% sorted.
The Hygrometer is seeming to be the hardest to sort at the moment.

A call from Ardex this morning gave the same info as the majority of manufacturers , dry, sand, prime, tile with your normal adhesive.

I did a 50m2 last week. I just used a sander and dust mask. It took me all day, it was like being on beach when i'd done so i hovered it all up and tried again to sand more off and i could barely touch it. 1 coat of bal apd diluted 1:1 left it to dry until next day then 1 coat neat on top. Saturday was a far worse day, 50m2 0f 60x30 porcelain grouted with bal superflex charcoal.

Not laughing!! lol

Hi AJAX123

the above is just what i have been looking for.... i will be using nicobond gypfix and i have been told it works best with 'no primer'.

My floor is 50-55mm thick and will have been down for 120 days before laying 22mm sand stone slabs/tiles.

May i ask, if the scarifer here is ok for the cleaning job?... HSS Hire - Floor Scarifier Hire and Rent the reason i ask, is because i cant view the links you have added on the next page to this thread.

Also, what is the difference between a stabilizing primer and a primer (whilst i will hoover and hoover, is it worth using a stabilizing primer?)

kindest regards
David

Sir Ramic, what primer & addy did you use in the end ? Looked at a gyvlon floor job today. So more questions to come in new thread.

I haven't started the job. It starts this coming Monday. I opted for Nicobond Gypfix and a primer is not recommended .

 

[Del W]

Thank you.

I am using that on my next Gyvlon in a few weeks time.

 

[Daz]

I used Nicobond Gypfix a couple of weeks ago. Nicobond say that there is no need to use primer. The pot life, open time and performance are exactly as stated on the bag in my experience.



I will be using it to fix these in a few weeks.....



And then I will be doing the remainder of the floor with 22mm honed sandstone - I can't wait :smilewinkgrin: :drool5:

What have you been using to abrade the floor ?

Did you have to do grinding/hoovering bit first

I used a belt sander with 60 grit paper. The sanded floor was thoroughly swept with a soft brush and then vacuumed with a "Henry".

It took a day to do 75sqm and I made sure that I was wearing gloves, goggles and a breathing mask. The sanding part is a proper dusty job :sick:.

Hi Sir Ramic, Just been reading up on this as i have a Gyvlon floor to price, how did it go?
How was the "Gypfix" i hate addys that go off too quick
What about the moisture tests / what did you use ?
what about the scarifiying how long does it take per m2 ?
did you use a decoupling mat ?
Thanks in advance

 

[Gazzer]

No decoupler,
Sanded floor with disc grinder/sander
Gypfix was great, plenty of fixing time.
Moisture test was required time plus polythene sheet test. which was 100% negative

Floor was heated too to aid drying.
