Blue grit fan

[lilharbs]

After using Only pva for priming etc in the past,I thought after reading about it on here I would give blue grit a go.big thumbs up,wish I had used it before And would recommend it for anyone who hasn't tried it.:RpS_thumbsup:

 

[beddy]

its ok. i only use it as its the only one readily available. its very messy! personally think micro is better but no where round here stocks it so its finding time to make a trip over to brum.

 

[lilharbs]

With the micro,how soon after can you skim over it?obviously if its just a couple of walls then I would just slap on the pva.

 

[DuffMcKaganIsClass]

Blue grit is too thick. Plasprime is the best I think

 

[Fatarm]

Dilute it then

 

[kebab king]

Come on Duff, you really a re a fukin fick twax if its to thick dilute it.

 

[DannyMac]

Micro isn't any good for shiney painted surfaces. It rubs off.

 

[DuffMcKaganIsClass]

As in the grit in it is too large and it takes a thicker first coat of skim kebab you dingbat. Fuk puttin it on. apology accepted

 

[DannyMac]

Isn't plasprime like double the price though?

 

[nickelarse]

blue grit is the worst bonding agent going. its like lumpy porridge

iv never experienced this and have used it for years

 

[kebab king]

Must get round to trying Micro.

 

[kebab king]

Anyway, none of us need any bonding agents now.B.G have kindly invented Uni finnish.

That makes it the best, gives it more scope for watering down. :RpS_thumbsup:

I took some pics of it, it's on one of the hundred threads similar to this. It needs a small amount of key and suction I think.

 

[DannyMac]

As in the grit in it is too large

I agree, about half the size would be ideal.

 

[DuffMcKaganIsClass]

And your not really supposed to dilute these products anyways . Plasprime is easier applied also

 

[Fatarm]

And your not supposed to use Pva either?:rolleyes)

 

[ELplastering123]

Blue grit gets my choice

 

[Arti]

what about watering it down with something marra...........:RpS_wink:

 

[DannyMac]

And your not really supposed to dilute these products anyways

Who said that and why?

 

[essexandy]

Who said that and why?

I didn't say it, but I wouldn't go watering down products that didn't recommend it in their instructions. I mean I don't know more about their products than they do, do I?

 

[Fatarm]

Who said that and why?

They( the makers of said product) don't want you to dilute it cause you would in effect gettin 2 for the price of one:rolleyes) I've been doin it per your tip Dannymac, no comebacks :RpS_thumbup: easier to put it on too when diluted

Like someone mentioned in another topic, you wouldn't water down water as it becomes more watery (unless is concentrated and you need the viscosity) :RpS_thumbup:

Not sure what you know, if you want to follow their instructions that's up to you.

 

[DuffMcKaganIsClass]

It affects your manufacturers warranty im sure so if it fails and the customer seen you watering it down youd prob have to redo it for free

 

[DannyMac]

:RpS_lol::RpS_lol: You're clutching at straws, the same way you'd be if you tried get anything back on the warranty. Ever tried it?

 

[beddy]

i find that blue grit goes from being really thick to like piss too easily when diluting it. i was using it yesterday and skimmed it today. how much do you dilute it danny?

 

[Arti]

Even though its canny thick you get good meterage out of it

 

[DannyMac]

Not loads TBH, like you say it has to be thick enough to evenly distribute the grit. I normally mix it with a strongish pva/water or sbr/water mix, maybe 2l to 10l bluegrit.

Throw water on it the next day and it doesn't re-emulsify and you can't scrape it off.

This is that test I was on about. It's on bathroom paint, IIRC left to right is neat bluegrit, microgobetis, watered down bluegrit.

As you can see neither of the blue grits could be rubbed off, but the microgobetis came off with very little resistance to my wanking hand. :RpS_thumbsup:

 

[bubbles65]

I'm sure on at least one product (I think either Betakontact or Thistlebondit) it says you can add 'up to 10% water' :RpS_thumbup:

 

[Curry]

Yes but that hand it mighty powerfully for some reason

 

[Curry]

Have watered down bondit a little and had no issues

 

[beddy]

i dont like bondit. i like wba but think for the price the amount you get is a rip off. betokontakt comes in around £70 a tub

 

[DannyMac]

betokontakt comes in around £70 a tub

Yeah that's good stuff. £70 is a lot but that's for a 20l tub isn't it?

I think we pay about £17 + vat for 10l of bluegrit. But the grit is bigger so you use more finish to cover.
