Painting boundary wall

Hi folks,

Any one have any recommendations or suggestions...

Had a new external boundary block wall built, capped and plastered last November.

Seems to have dried out and am hoping to paint over coming days. Might wait for temperatures to come up at the end of this week and do it next week to be sure.

How should I go about it? Does it need to be polybonded first? Should I water down the first coat? How many coats will it need?

Any help would be appreciated...

1st, Use an alkali resisting primer on the capping, then 2 coats of exterior paint.
On the plastered wall, thin 1st coat by 10% water, also add in a product called floetrol into 1st coat, it aids adhesion, then apply 2nd coat.

Floetrol isn't a bonder, its a paint conditioner. Water down first coat by 30%. Apply 2 more full strength coats on top. On the first of these coats, add in a product called Owatrol EB. This is a bonder and stabiliser in one, expensive, but well worth the money.

Thanks a million. Is there anywhere I could get the bonder at the moment? I am good to go except that and have the time at the minute to do it.

Hi Dok. About to start this painting job tomorrow.

Just checking - is the first coat just paint and water and then the first of the full strength coats gets the bonder?

How much bonder should I add?

Thanks in advance.
