Masonry paint advice. EP

CharlieRabbit

Folks,

Our cottage was painted last year and it needs to be done again. We power hosed off the old paint. It was flaking of very badly and it came off in lumps. It looked like dampness had got in behind it and there was a fungus growing in places.

The paint we used last year was not branded and was on special in B&Q. I think we didn't wait long enough before starting to paint. The walls may not have been fully dry. We've been advised to get Dulux Weather Sheild and mix in EP? It's some sort of bonding agent.

A guy I know in a paint supply shop said that most painters worth their salt would not mix anything with paint and what we need is a primer.

The primer is expensive but I would prefer to take the hit now and not have to paint it again in a year or two.

Any advice?

Cheers,

Charlie

Ok you heard right - do not mix anything with the pain. As for primer go with sandtex stabilising solution and let it dry out. Then use either dulux or sandtex. It may be expensive to do but it will work out cheaper than painting it every year. If you do it this way dont expect to have to paint it til 2011 - unless you decide to change the colour.

btw I was a paint specialist in a big DIY store for years and received training from every paint company going - not to mention the great advice some customers can give.

Its worth noting the difference between sandtex and weathershield. Sandtex has a gritty texture and you cannot use it in a spray gun (the best way to get the job done quickly). Weathershield is smooth so you can use it in a sprayer if you water it down a little - you may need to do a couple of coats this way.

Do the well known paint manufacturers do the own-brand paint for B&Q, Woodies, Atlantic etc. ?

Do you know which is better between Santex and Dulux?

Santex or Dulux whichever is cheapest,either one will do as they both are good.You can also get Sandtex in a smooth paint and not textured.

Folks,

The walls have a fungus type growth in patches. Can I put the stabilising primer on first and then the anti-fungus primer or do they not go together?

Woodies are selling Sandtex masonary paint for 40 Euro a bucket (10 lt) compare to dulux weathershield at 52 Euro. Are these two paints the same in terms of life span?

Thanks,

Charlie

TBH you're wasting your time painting or priming untill you tackle the fungus/moss, whatever.

I'm afraid it's a crappy job, but dilute up some bleach in a bucket, grab some rubber gloves and a wire brush and start scrubbing. Leave it then for a few days, to let the bleach kill the growth, then scrub again to remove the dead growth. Now start painting.

Do this, and your paint job will last that 5-7 years.

Does anyone know if you can use EB bonding primer and mix it with a masonary paint to paint a wooden garden fence?

no,you cant paint timber with masonry paint!

I have a small crack in the plaster and the paint has come off a couple of inches each side of the crack. What's the best way to treat this before repainting.
