Like Paddy said, do NOT use P.V.A.
Like Robbie said, just use a wooden stick and stir....should take all of 45 seconds to do![and will save you having to clean the mixer bit].
Wayoutwest says,just get on with it-its not rocket science
So you cant/shouldnt use a "mains operated" drill or mixer for mixing/diluting down paint then???
I guess Lidl cant and dont sell any of these then...
PS-Im not telling the OP to go and buy one of these,Im just using this machine as an example,thats all.
Paddy that tool in the link for mixing is a specially made and designed
for use with water based products.
The handle is alot further away than a drill would be with your mixer on the end of it and it would be alot better sealed up incase splash's of water comes into contact with it.
Heres a question for you Paddy would you use a mains operated drill out side to drill a hole if it was raining?
