Hi

Has anyone heard of this product being used in the past to stop the likes of multi finish going off too quickly in hot weather.

I was once told by a guy in the know that it was a tradesmans trick to use the cooking preservative by adding a tablespoon into the water before mixing in the multi finish and this will give you a lot more time when working on bigger walls and ceilings on warmer days.

Anyone got any experience of this? Or is this some sort of old wives tale?

the spread I use insists on chips for lunch, which seems to stop the plaster going on at all in the afternoon

There are quite a few of these so called old tricks going around, a common one is to add pva to the plaster :shock:

I would not believe any of it, only add to plaster what the manufacturers recommend, mainly clean water.


I have also head of people adding washing up liquid to mortar to make it easier to use, but what is the point when you can just buy a dedicated admix?

The general concensus then, is that its all a load of.

Is there anything apart from working like hell fire that will stop the mix from going off too quickly when working in warmer climes?

Andy-p will probably have some good tips for this, but I would say to make sure the bag is new plaster and not an old bag that has been in storage as it goes off much quicker. Using a two coat system instead of one will also help as it gives you much more time.

Over to the pro's now-

Fairy Liquid has worked for me in the past. The idea is simple, washing up liquid reduces water surface tension for a smoother mix allowing easier application, thus reducing time to apply...but wether it goes-off slower I don't know, its something my Dad told me years ago I wonder if that counts as an old wives tale?!

Just noticed going throught the forum that andy-p swears by wickes bonding agent.

If andy-p is out there could he tell me if wickes bonding agent would help give more work time on larger jobs in warmer times? Or is it solely down to the amount of water used in primary mix?

Have a look at the pdf attached on page 23 at the bottom. It says that adding cream of tartar will give more working time to finish plaster although I think this publication is american which may say a lot.



FROM THE PDF WHICH I CAN'T SEEM TO ATTACH.
A variety of textures ranging from sand float to Spanish can be achievedwith DIAMONDBrand Interior Finish Plaster when job-aggregated with sil-ica sand.(When DIAMONDBrand Interior Finish Plaster is job-aggregated,one tablespoon of cream of tartar or 1.25 mL (.25 teaspoon) of CGCRetarder for Lime Containing Plaster Products should be added for eachbag of finish to retard plaster and allow sufficient working time.)

THIS LINK WILL GET YOU TO THE PDF

With wicks p/b/a your skim will not be affected by the suction of the background so it will not pull in really quickly.
Years ago i used to think if i mixed up a little bit wetter i would have more time then if it was slightly thicker. Not true. Youll still have round about the same amount of time.
In my opinion you should not put anything in your skim. When you become more experienced you become quicker, so you dont get that sort of problem unless you put a huge set on :cb .
I usually mix up a gorilla tub full to the top for 1st coat which is about 1 1/2ish bags of skim which i can get on with no problems.
Wicks p/b/g will help you or 2 coats of pva and go on it when nice and tacky. Dont put too big a set on.
PS i aint used wicks b/a for 2 weeks now just pva

I used wicks pba on andy-p's advice and noticed a massive difference, especially on ceilings where it goes of quicker anyway.

Give it a try on your next job, i was impressed. other than that,,,,work like crazy until you get quick enough not to panic.

I've noticed a couple of strange or maybe natural phenomenons when looking at all the tradesmen we've had on site here.

I've seen a FAT electrician.

I've seen a FAT plumber.
(I remember one that had to send his mate back coz he was too FAT to get through the smaller loft hatch at Mums house. Now he was a FAT fecker!)

I've seen a FAT **.

I've seen a FAT chippie.

I've seen a FAT labourer.

But I've never ever, ever seen a FAT plasterer!

Now you know why. :grin:
