sHow To Remove Expanding Foam From Composite Door?
If you've ever used expanding foam, otherwise known as spray foam, to seal doors and windows, you'll know that it can be difficult to remove if you make a mistake.
Luckily, here's a quick and easy way to get rid of expanding foam from a composite door.
What Is Expanding Foam?
When UK composite doors are installed, expanding foam is often used to fill any gaps around the door frame.
There is fully cured foam and uncured foam. The uncured expanding foam is called polyurethane foam. This foam expands and hardens over time.
The liquid foam can expand to almost 60 times its original size after it hardens and does not expand or contract in heat or cold.
Why Is It Used On Composite Doors?
Expanding foam is used on composite front doors, back doors, windows and more because it provides an excellent sealant against drafts and moisture.
It's an insulation foam that is super reliable for installers to use across the world.
Removing Expanding Foam
Here are the steps to take to remove excess expanding foam.
- Start the process by scoring the foam with a plastic scraper (to avoid scratching surfaces) or a utility knife. This will help the solvent to penetrate the foam and dissolve.
- Apply a thin layer of solvent cleaner to the area where the foam is located. Use a brush or dry cloth to work the solvent into the foam. You might need to sand the foam down if this doesn't work.
- Let the solvent sit for several minutes before scrubbing at the foam with a stiff brush. The goal is to loosen the bond between the foam and the door so that it can be scraped away.
- Once you've loosened the bond, rub the area with a sponge. Work slowly and carefully, so you don't damage the door surface.
- Repeat steps 2-4 as needed until all of the expanding foam has been removed from the composite door.
- Wipe the area with warm water to get rid of any product.
Avoiding Damage When Removing The Expanding Foam
Here are some tips on how to avoid damage:
- Use a putty knife or another blunt object to scrape away the foam. Don't use a sharp object, as this could scratch or gouge the door.
- Use plastic wrap to protect adjacent surfaces.
- Too much acetone can damage stone and wood surfaces.
- Be careful not to apply too much pressure when scraping.
- Use gloves - wash your hands with soap after.
