Applying primer - advice please :-)

[Gixerguy]

Morning all!
I have had a nightmare previously with tiles and thanks to your site Im making progress again lol i have a question about the Granfix acrylic primer - the instructions for plaster priming say to mix 3:1 water to primer and apply to seal. It then says apply 2 neat coats before using cementitious addy. Am I reading that as my walls need sealing 3:1 then a further 2 neat coats before tiling or "if used as sealant do 3:1" or "2 neat coats before addy". The salesman said just 3:1 and off I go but you guys are the pros - he's only a salesman for a reason lol
Also, whats the drying time before addy is applied? Should it be dry, tacky, ?
Thanks in advance for your help with this!!!
Cheers!!

What adhesive are you using Gixerguy?

And what you fixing to?

 

[Gazzer]

What adhesive are you using? ready mixed or cement based?

 

[faithhealer]

I think its telling you to apply a 3.1 coat to soak into the plaster then two coats on top. I generally use 2 coats of 3.1 or three if I have some primer to use up ! Drys in an hour in normal room temp

 

[Gazzer]

Its 3.1 if using a ready mixed adhesive or 2 coats neat if using a cement based adhesive.

 

[merlecollins]

Deffo not 3:1 THEN another neat 2 coats....:yikes:

You just need the neat coats on their own when using cement based as it reacts with the gypsum plaster background

I have used granfix acrylic primer many times, 2 coats and away you go, first coat dries in minutes, second about 40 mins depending on room temperature.

|I would use Water Dispersible Epoxy personally......

Dead right - I would have said about an hour for the two coats before tiling

 

[Gixerguy]

Thanks guys! I forgot to mention the addy lol its granfix powder so it'll be two coats neat then addy

Im guessing I ought to do the tanking first as well to get the overlap the right way too ?

Cheers!

 

[Gazzer]

What tanking are you using ?

 

[diamondtiling]

Is that a sealer Al ? Never heard of it before, I take it its a brush/roller type sealer?

:dizzy2:

Can we stick to the thread please...this is not about what product to use but how to use this particular product mentioned.

 

[Gixerguy]

I will probably use a BAL WP1 kit as it's popular on here so thats gotta mean something lol unless of course there's a better option?

 

[diamondtiling]

What tanking are you using ?

He is not asking about tanking either Neale, I thought Jay's point was valid for others that may not have purchased a primer but might be looking for advice anyway.

Jay did not ask anything ?? Ajax made the post about epoxy primer and i feel it would be better started in another thread.

 

[Gazzer]

If i were tanking then i would use a membrane and not a paint on system, just my opinion!

 

[diamondtiling]

Are you sure Dom ????

forget all that, I will go and get my glasses.

Have a beer on me Neale.............:8:

 

[Gixerguy]

Thanks Sir, is the membrane a more reliable method?

horses for courses, its like everything in life, we all have our favourite or preferred methods.....membrane for me all the time. I find it a lot quicker and cleaner.

 

[kilty55]

hi gixer i have only used the paint on tanking kits so far,i have found the best for me the pci lastogum kit its very simple to use and is half the price of al others and just as good ,good luck

Please will you point me in the direction of a membrane. I would like to try something thats quicker and cleaner than the paint on type.

its a good idea to buy a little marshalltown internal angle trowel for applying the corner strips

they cost around £10 but they really come in handy for lots of applications.

pleasee help i am really worried. I am worried i have ruined the gypsum plaster and will need it replastering.

What does it to do gypsum, I've just applied a weak solution of granfix onto gypsum, and then a neat coat, will it ruin the gypsum plaster? will I need it replastering?
I need a whole new kitchen and I cannont afford one, here is a picture to show what I have done
