Can you put anything in paint to stop mildew or mold ? Living in a third world country so supplies are limite

I am living in Belize and it is damp here in the jungle.I painted a cabana and where the new bricks are it is moldy. I have essential oils and am using oil based paint. I have washed it but it still looks dirty so have to paint it again. Any ideas what I can add to the paint?Can you put anything in paint to stop mildew or mold ?

This was a response to a mold problem to an individual living in Sumatra, Indonesia. I thought it appropriate:





';You couldn't be more correct... removing the moisture is the number one solution to mildew problems. In the United States, mold and mildew inhibitors can be purchased in any paint store in either interior and exterior strengths. I can't imagine why you can't obtain them in Indonesia, especially if mold is such a problem.





If they are banned for some reason ( which would explain why they are not available) you should be careful to not break the law by importing them. That having been said, I don't know of any company that would mail order this type of product. However, it would be an easy matter for you to have a friend or relative here in the states just purchase the product here send you a bottle or two.





This type of product is called a ';mildewcide';, and is available in interior and exterior grades, based on the amount and type of active chemical used. The chemical is added to the paint and the paint shaken thoroughly. One container usually protects one gallon of paint, and it may be added to any paint, oil, alkyd, or latex.





I have another suggestion, and that is to use oil paints instead of latex paints whenever possible. In my experience, oil paints are less attractive to mold and mildew than latex paints. You will be increasing your home's overall resistance to the mold by using them.





There are also some special steps to take in preparing mildewed walls for painting. The mildew must be killed with bleach. You can use a premixed mildew killing product, or DIY by using a mix of 50% household bleach and 50% water. Apply the product to the walls, allow it to remain for a few minutes, and wipe clean. To add some cleaning punch to this mix, add 1/8 cup of TSP (trisodium phosphate) or TSP-substitute to the bleach/water mix. TSP is not legal to use in some states in the US, so it may well be banned in Sumatra, also!





Once the mildew is killed, the walls should be primed with a primer sealer before finish painting. This will reduce the overall porosity of the walls, seal in any stray mildew staining and give you a more even paint finish.';

this is a mold inhibitor additive that comes in a packet that you can add to any paint. you can get it at any home improvement store or paint store. maybe you can get someone to send you some.
No....Sorry. The paint has nothing to do with the mold or mildew. It simply adheres to the painted surface. Just keeping it clean would help. In a high humid climate it is pretty impossible to keep it dry.
Oh, that's tough. I'm sorry. Here in the States we can buy primer that contains a chemical that kills stains and mildew. So my suggestion is to look for a paint primer that would be compatible with the oil based paint. If you could get Kilz paint, that would be great. Do you think your supplier could order some paint with a micro ban or something similar in it. Good luck. Why don't you go talk to one of the hotels and find out what they use.
Paint is only going to be as good as the surface it is applied to. There are additives that they put in paint that make the paint resistant to mildew, but nothing that prevents it entirely.





You will either have to live in the moldy house or seal it up better before repainting.





Mold isn't necessarily bad for you. Excess mold is. A cabana doesn't likely have more mold in it than the air outside, so you don't have to worry about any ill effects on your health.
Wash the surface first with Chlorine bleach. That is the best fungicide. Then put on a good primer that is designed to seal in oil based paint and paint with an elastomeric type paint.





Oil based paints have a very low vapor permeability rate so all light colored oil based paints are going to look dirty in that environment as the moisture in the substrate tries to escapre and takes dirt and tint with it.





Some coating systems like those from Rhino Shield (Rhinoshield.net?) and http://www.hytechsales.com have a tacky primer that would be perfect to seal the moisture out while allowing the substrate to breathe.
