Hi Mike when I mean roughcast park homes by water, its a mobile home by a stream I had to paint the exterior which was roughcast.I used a chemical to kill the mildew but it left staining ,the whole unit had mildew around it, to try and remove staining I used bleach and left on as the manufactures recommended, it helped remove the staining,was going to use a stain blocker but it got rid off it.Any recommendations on a good zinerser stain blocker or other tips on killing mildew.
Mike, thanks for all your insight on this subjects. Despite the good intentions of people on different forums, I've never read such a thorough explanation of the mold remediation process.
Since proper surface prep is so important I'm very curious about TrueCleanEX house wash for exterior projects. Beyond killing mold & mildew is it effective at killing algae? In my area we get a lot algae growth and without a strong enough chem mix it's very tough to remove algae without using high-pressure, which I don't recommend due to the potential surface damage that high pressure washing can cause.
My current house wash mix consists of 5oz eLemonator (sold by Pressuretek) 3-5 gallons of 8% bleach and I fill the the rest of the 5 gal bucket with water. This mix is downstreamed with a pressure washer and I let it dwell on the siding for 5-15 min before I rinse the siding. To date this mix has been very effective.
Since I've never used TrueCleanEX, do you have any recommendations in terms of dilution ratios? The products webpage says you can dilute up to 40:1, but in the real world what range of dilution ration ratio's have you found to be effective? Also, do you add bleach to your mix? The webpage says it can be used with or without bleach.
Mike, I can use some advice on a bathroom ceiling that has a mild issue.
I bought the the 20 Mule Team Borax Laundry Detergent Booster and mixed it in a spray bottle so it's roughly the concentration you previously mentioned. How do I know if this has actually killed the mold spores?
The paint and texture in the ceiling is peeling off, but I'd like to do everything I can to stop the spread of the spores when I sand or scrape off everything that it peeling.
Wow thanks for your research. I do drywall repair and painting. I always worry about this did I kill the mold or not? Scrap remove , or mirka sand. No hepa filter in the vac . Hit with some shellac bin. Tape / float etc. Question so hitting an area like from the above picture . Mix a solution of borax and hot water. Kill the mold. The nest.... Let dry. Prime with shellac. Patch or paint. Correct.
I finished the job today and everything went as planned. I followed all the steps you mentioned (borax, mold killing primer, etc.. ) and used SW Super Paint in Semi-Gloss with the M1 additive. Hopefully that will hold up well.
All 49 units in the apartment building were remodeled and repainted within the last 3 years. Whomever painted all the bathrooms used something like SW Builders Choice paint in low or flat sheens for all the walls and ceilings in the bathrooms. Needless to say they will all fail since these paints won't hold up well in a high moisture environment.
Hi I have a mobile home that's roughcast ,I have done a few now,for the mildew stain left once cleaned with fungerside I am going to use zinerser coverstain in spray can this is for exterior any thought?
