Method 1. The Traditional Scrape
Scrappers are a traditional way of removing excess residue on the roofs and ceilings of the house or an RV. A caulk-type material is present, for which the removal can be a little difficult as weather matters a lot in this. If there are heavy clouds or cold weather, you may require a hot gun to soften the caulk if there are heavy clouds or cold weather.
- If the weather is cold, use a heat gun or a dryer to soften the material.
- Some alcohol or non-chlorinated cleaner.
- A metal crowbar consists of a flat end for the roofs that are fiberglass. Or even a plastic scraper will work.
Scraping Old Sealant
1. The first thing you can do is to scrape the sealant off from the place of your roof where it is stuck.
2. If the weather is cold, turn on the heat gun and the surface where the caulk is present to soften it so that the removal can be easy.
3. Plastic scrapers can be used if the roof’s surface is sensitive, like rubber roofs. It can also be used for the roofs like aluminum roofs, but with a little bit of elbow grease can be used to speed up the process.
Ensure there is no Residue
Some of the stuff might still be present even after scrapping. For that:
1. If the caulk is not being efficiently removed, another trick for the removal is to wet the rag with the given non-chlorinated cleaner or if you want to use alcohol.
2. Rub the wet rag over the stubborn caulk on the roof. This will help you to prepare the roof for the implantation of new sealant.
If you are consuming isopropyl alcohol, you will have to give it some time for evaporation as it can react with sealant products.
Method 2. Use A Power Tool
A more effective way if the caulk is not getting off the roof is to use a heavy tool.
- An oscillating tool that has a scrapper.
- A wire wheel
- Power drill
Use The Oscillating Tool
Instead of a scrapper, an oscillating tool is much more efficient in getting rid of sealant. If you own an RV with a rubber roof, ensure its blade does not damage the rubber and protects its soft membrane.
1. Initially, keep the speed of the unit slow after turning it on.
2. Angle of the tool should be precise while removing it to make sure to remove the right amount of sealant.
3. Gradually increase the speed of the unit, pointing towards the sealant for better removal.
Take Care of Narrow Areas
A wire wheeler and a degreaser can help get rid of the remaining sealant as an oscillating tool will remove the old gunk quickly but not if the sealant is surrounded by screws or is present in narrow areas.
Put the wire wheeler inside the unit of a power drill.
Rub the areas where you see the sealant residue after using oscillating tools.
If there is some silicone, you can also use a wire wheel for the removal.
Method 3. Special Solvent
The sealants with silicone are the hardest to remove from the roofs. Proflex is a silicon-based sealant and is way trickiest to remove. Mineral spirit or turpentine are two magical ingredients that can be used if the RV roof has a Proflex silicone roof. These solvents cannot remove fiber glass sealant, so checking the label before using it is essential.
- A solvent that has a silicone remover.
- A blade or a tool capable of removing silicone.
- For roofs made up of metal, a nylon scrubber.
Use Silicone Remover
The area should be clean and not wet before you spread over the solvent.
1. Spread the silicon solvent on the roof and wait for a few minutes for it to settle down
2. After it is settled down, the swelling of the material indicates that it is ready to be scraped, and it can be scraped out using a gentle or soft scraper.
3. For the removal of the silicone sealant, use the silicone removal tool. The blade will cut directly into the swelled caulk; if you cannot find this tool, you can also use the razor blade for its removal.
Leave no Residue
After the application of all of these steps, you might see some of the sealants still present on the roof, and this last step is to make you aware of how you can get rid of it for the roof to be ready for a new sealant.
1. Take a cloth and make it wet to remove any residue left behind.
2. Use a bristle brush or a nylon scrubber if you still see some parts of the sealants left.
3. Use a hose to wash off the sealant.
More Tips To eliminate RV Roof Sealant
1. Because the solvents can react on the skin, do not forget to wear gloves.
2. For your own convenience, do this Job on a day when the weather is not too cold, and the caulk is not too stiff for removal.
3. To prevent any other damages like scratches, use a gentle scrapper for the removal of the residue. However, it is essential to use a bit of hard scrapper as it is slightly tricky to remove sealant from metal surfaces.
It is straightforward to remove the sealant from the roof of your RV, but some kinds of stuff on the roof need special tools and special care for the process of scrapping. A scraper, a power tool, or a solvent all of these are the solutions to how to remove the sealants from the roofs. The basis of this is being cautious and not doing any type of damage to the roof and keeping it clean for the application of the subsequent sealant.
