Primer Required For a Concrete Wall

Featured Replies

Hi gang

 

I'm a bit stuck on what type of primer to use for a concrete wall on the back of a property.

I'll probably use an acrylic flat paint from Dulux as a top coat.

 

I've read numerous posts about sealers/primers.

Can anyone recommend a decent primer that will do the job?

 

Thanks in advance.

I just use the cheapest primer from Global house, 2 or 3 coatings and watch how it has obsorbed before final 2 coats of top coat.

Thanks for that.

 

It's a pretty big job though, so I don't really want to give

It several coats.

 

I'm hoping to get away with 1 primer and 1 top coat if possible.

Depends if the wall has been primed sealed before if it has OK.

A good prepared prime sealed wall you could get away with 1 top coat, you will easily be able to see that when it's dry.

Is that a new wall?  If so, you should allow plenty of time for curing.  If you want the paint to last 10 years or more, go with the premium grade for both primer and color.  (And clean dust, etc. from the wall before applying).

No, the wall is old.

 

Most of it is out of sight, so no point (IMO) going for top of the range paint.

 

A decent primer and Dulex top coat is what I'm after.

OK.  I would wonder why paint at all then.  There is a big difference between premium grade and ones that are not.  Just make sure you get primer designed for rendered wall.

Because the areas that are visible, look terrible.

 

You can still get some decent paints that aren't premium.

For me it's premium grade or nothing because I see what happens otherwise.  If the paint defines its purpose on the can, I would think maybe "decent".

I used premium grade for the house exterior.

 

There's over a 100 meters of wall so there is no way I'm 

going to use top of the line paint.

 

I've heard Nippon and ICI (Supercote) make some decent primers.

 

Just after some suggestions for a decent primer.

I have bought National Brand primer and exterior paint for a village wall. It has served me well in Buriram. I have bought Dulux paint four years prior for the same wall. National paint is a budget brand of Delta paint in Thailand. Under 1000 baht for five gallons. Like any inexpensive paint it is mixed at the paint plant. It took a bit of Lanko 107 and Dr. Fixit to patch the wall prior to sealer | primer. I've learned it pays to primer the rear side of the boundary wall, so less damage to the side on my wife's land.
