Masonry Paint - Undercoat

Always_Harassed

Am taking the outside of a dark painted house back to light brown. I asked in the paint shop about using an undercoat as it is such a big change of colour and it was suggested that I use emulsion as the undercoat and then a good quality masonry paint as the top coat. Is there anyone in the know that can advise me if this is a good idea.

no emulsion is for inside , masonry paint is for outside , just use the masonry paint and give it however many coats it needs , 2 should be plenty

What he told me was that emulsion paint was the starting product and then more ingredients were added to make it masonry paint.

Interior paint is interior paint. Exterior paint is exterior paint.

what shop was it that actually told you this ? i do not know of any reputable paint store that would give such misinformation ,
if it was the case to put emulsion on the walls and then masonry paint such instructions would be given on the side , if the tin has such instructions then i stand corrcted ,
i would imagine that if you did go down this route then you'd have to change your user name to always extremely harrased

if the colour change is so drastic it will require 3 coats many painters would use emulsion as a 1st coat TBH I can't see the problem, if you were planning to use emulsion a top coat that would be a different story!

many [STRIKE]painters[/STRIKE] bodgers would use emulsion as a 1st coat. See Post #4.

As others said emulsion is for interior its not designed for external use.

no genuine painter would do this , they would just allow for more masonry paint in their quote . they are , give or take a couple of pounds the same price so why would anyone bother getting emulsion .
you are talking rubbish

thanks but as a decorator with 12 years in the trade I can assure you that many decs will do this, finding ones who'll own up to it in public is a different matter:rotfl:

i've been in the trade for 30 years and all the people i've worked with have never done this ,
maybe the people you are thinking of aren't actually painters but cowboys/bodgers ,
painters who care about their work and reputation would not do this ,
if the paint all comes off you'll have a hell of a job putting it right and it will cost far more than a coat of emulsion , it's not worth the risk
, i guess the people you are thinking of will have taken the cash and disapeared when it comes to putting it right .
why would you put emulsion on when masonry paint is the around the same price
