Paint exterior pebble dash house

1930’s mid terrace house with what appears to be original pebble dash (un-painted) which is looking aged and in need of decorating.

Before I get quotes I wanted to get a better idea of the task and ask a few questions:

1) is a breathable sealer advised as first coat, if so, what type of mix/ product is best?

2) is an undercoat used prior to painting, if so, what type would be advised

3) is masonry paint best/ advised?

4) how many coats from start to finish should be allowed for?

I would suggest you look at zinsser exterior coatings range. Plenty of advice online, and/or as i always advocate here, find a good local decorators merchants and go have a chat to them

As well as the Zinsser products it would be advisable to look at the surface for any movement cracks, if this is the case a flexible coating would be advisable. Generally an exterior requires a stabilising sealer, followed by 2 to 3 coats of exterior paint - Sandtex or Weathershield are both tried and tested in the trade and some products do come with a guarantee. Brewers Decorator Centres give impartial advise.

I personally would scan the area visually for cracks or faults problems... I would then recommend maybe a 1st coat of a pva breathable sealer then 2 together coats of high Matt weathershueld paint

I have recently painted another house with 1930s unpainted pebble dash, I would repair all cracks ect , then seal the whole area then apply 2 coats of santex exterior masonry paint. Which I have used many times before & always achieve a great finish plus it's long lasting.

stabilising primers are best recommended then flash coat followed by 2 undiluted coats of santex masonry paint, the deeper the pebble or stone think to applying by spray method in my experience.
Always employ an experienced painter.

Before you apply any paint I would personally coat the wall with two coats of stabilizing solution, this can then be followed with three coats of chosen masonry paint. Dulux weather shield/santex/Johnstone's storm shield would be my recommendations for you to use.
