I know paint doesn't last very long outdoors in Fuerte but it's flaking away on my garden wall and it appears to be dampness! Does anybody have a similar problem and could you recommend any chemical etc to put a seal on the wall?

That is the stuff I ltre bottle circa â,¬7 bough that from the Freteria in The Monte Castillo Centre, but probably available elsewhere, It is a branch of Honduras, they are all over The Island in the one I bought it at, turn right as you go in, and it is on the shelves in front of you.

So why is your wall damp? Before painting/sealing it I'm guessing reducing or getting rid of what causes the damp would be a good first step.

I don't care what you try it will only work for a short time as a lot of the problem is not only damp but the fact that the render does not have any salt inhibitor in it and it is mixed with desalinated water, the only thing to do is remove loose paint scabble the wall ( rough it up) for a key and pick a nice tile, then tile the offending area, this what i have done on my house and many others no problem if it is done right, hope this helps.
Yes that certainly works. Or with a bit more effort, remove all flaking paint and in very bad areas, any crumbling Render. Then apply a couple of coats of the Puma sealer that has been mentioned. Then rerender with "copa fina" Render, re apply a coat of sealer and then paint and you should have no problems. 2 years on the walls are still sound that I used to have to repainted every 6 months. Water penetration was from a higher soil level from next door.
Hi, You could look for a salt neutraliser like in-virol, a 1 litre bottle will cover 5-10 square metres. Then seal with something like Thompsons Water seal then paint. I had the same problem in Turkey. Had to take the stuff out with me from the uk. Also you can buy tubes of damp injection fluid that can be dispensed from sealant gun. Drill the wall 6 to 9 inches apart with a 10 mill drill and as deep as you dare fill with fluid and plug later with sand and cement. Natural capillary absorption is the predominant mechanism of water transport through concrete.
Good luck,
Paul.
You might consider paying a professional company to resolve this for you. I have been very impressed by work completed by Wharton's Professional Painting and Decorating Services in treatment, making good and redecoration of difficult external surfaces. Worth ringing Lee Wharton for a quote. 626 817 352
Maybe waterglass....No, not a waterglass but waterglass or liquid glass,
Sodium metasilicate, (Na2SiO3). A Sodium silicate (Na2SiO2)nO.
Look it up on wikipedia. It has a lot of uses (you can even conserve your eggs in it)
We used it to conserve and waterproof ancient clay walls.
Anyone know where i can get some Fijamont Anti Sal Stabiliser to prepare symyrfaces for painting?
Thanks
Yes, you can get it in the paint shop just up from IKEA.
Agreed it is called Monto
