zampa would just like to jog my memory. when i used to paint outside walls i think we used to use water based masonry but before hand we used to use uni bond on the wall first then paint the masonry paint on does this sound right to you? what is the advantages in using oil based masonry paint than water based? would the oil base paint keep all the staines from bleeding though the paint? thanks carl
I wouldnt recommend using PVA under ANY masonry paint let alone pliolite based stuff..all this PVA business is a total old wives tale..if its new render then all you need to do is thin the first one by 20 odd % so it can lock onto the surface insteasd of sititng on the top.
Advantages of oil over water..to be honest paint and durability wise none..some water based masonry paints give you 15 years guarentee on it..(providing its on a new surface and you follow their instructions to the letter)
The only thing I like about pliolite is the fact that its shower proof in 10-15 minutes, its really saved my bacon once, hot sunny day nice straight forward outside job above a brand new block paved drive...just finished and over come the blackest cloud in the history of clouds!...and down it came, like a monsoon!..im there, thinking about solicitors, block paving firms, anger customers, insurance premiums, alsorts..
The paint didnt budge!, if it had been water based id have been in one of those 'canoe in a creek full of faeces and no paddle' situations!
But I agree with 'Le Growl' (6 time this year not bad eh!!
) stick to the wate based gear.
