A combination of wet sand and lime putty have resulted in something close to a lime soup. Anyone any suggestions as to how I could dry it out a bit without having to wait a couple of weeks for it to stiffen sufficiently to use?
In my limited experience the only course of action is to stick it all in a bucket and wait for the soilds to sink so that you can decant the water off the top. This may not take that long - perhaps a day or two.
Otherwise it's a trip to the sort of place where sand is stored inside - you know what I mean. No good though if you've got lots to do.
Others will be along shortly to advise against doing lime work at this time of year.
Wot Andrew said - just let it settle for a few days, pour off the excess and knock the rest up again. Provided you cover the work to keep frost and rain at bay, there's nowt wrong with using lime at this time of year - the only drawback being that it will take five times as long to carbonate if the temperature is below five degrees, so your timescales get longer and longer.
In a break with tradition, I must agree with Nemesis. :wink:
When our wall was being rebuilt, the final section was finished at around this time. All well covered with hessian etc. but obviously the frost got to it and that section had to be rebuilt in the Spring.
I've had the trouble of lime soup before, from using wet sand, even though it doesn't feel that wet. It always happens when you havn't got time to mix up a new batch. I found that if I spread it on a large wooden board and left it for a few hours, a lot of the water would soak into the wood. Knocked up again the plaster is workable,.
Thanks for the advice. Threw most of it back in the mixer this morning for a couple of hours and the stiff wind seems to have dried it out quite nicely. Since I was also plastering onto a long dried out scratch coat I didn't dampen the surface down as much and it went on well - even managed to compress most of the surface by late afternoon. As to whether it's still on the wall tomorrow..... :wink:
Never had a problem over the past couple of years with internal plastering. The internal temp (without heating) only ever got down to 3 degrees and that was only for a couple of nights. Fortunately the house is well sheltered so seems to maintain a reasonable internal temp. Heating should be on soon so should be able to bring the internal temp up to a more manageable level (10 degrees or so).
Nice idea about the wood - I have several large bits of plywood left lying around so I might give that a go next time.
