Always Wear Protective Gear

Wearing personal protective equipment (PPE) is crucial when removing spray foam insulation:

The EPA recommends you wear long-sleeved shirts and long pants, closed-toed shoes or boots, eye protection, and gloves to protect yourself from exposure to the chemicals in spray foam insulations. You should also wear a hat to keep off any falling debris.

Invest in quality respiratory protection before tackling this project if you have an allergy or asthma. If you’re unsure what type of mask you need, consult an air quality professional who can recommend the best option for your needs. An N95 dust mask will provide enough protection against inhalation hazards during removal but may not be sufficient when working with chemical vapors such as formaldehyde.

Cover Flooring and Furnishings

You can cover your flooring and furniture with tarps instead of plastic sheeting. Tarping instead of plastic sheathing reduces the risk of the spray foam sticking to your furniture since tarps are more porous than plastic sheets. In addition, a tarp is easier than using plastic sheeting because you don’t have to worry about finding a way to secure it in place without damaging your floorboards or other surfaces. You can buy large tarps at hardware stores or online. 

Consider Which Spray Foam Removal Method to Use

If you’re going to remove spray foam insulation, it’s best to determine which method will work best for your job. Here are some factors to consider:

  • Size of the job. If you’re working on a small area, like a window sill or under-sink cupboard, you may be able to use a solvent that has low toxicity and is safe for skin contact. However, if you’re working on flooring or ceilings where there’s no ventilation present—and where toxic fumes could linger for hours—it’s better to use a more effective but potentially dangerous substance like methylene chloride.
  • Location of the job. The location of your spray foam insulation makes an enormous difference in terms of safety considerations. A small room away from people and pets will have far less risk involved than an attic full of insulation that can’t be reached easily by ventilating fans or heaters. The ideal situation here would be installing fans during installation to avoid long-term exposure problems later down the line. However, this isn’t always possible due to budget constraints or the lack of electrical outlets.
  • Type of foam used during the installation process (polyurethane vs polyisocyanurate). Polyurethane foams are typically less dense than polyisocyanurate ones. They don’t contain allergenic components such as formaldehyde either, so they tend not to pose serious health risks unless they’ve been contaminated by other substances such as dirt/dust particles.

Extract and Dissolve the Foam

If you’re dealing with a small amount of spray foam, you may be able to pull some of it out. To do this:

  • Use a vacuum to remove as much foam as possible. If you have a shop-vac, use that instead. If not, there are plenty of other options available at your local hardware store. Ensure that whatever tool you choose has high-quality suction power and is not prone to clogging up on large amounts of debris (or get one professionally cleaned in between uses).
  • Make sure your tools are completely dry before using them on live wires or anything else that could create sparks or start fires!

You can then dissolve the remaining foam with a chemical solvent. Always work in a well-ventilated area with plenty of fresh air. If using aerosol cans or spray nozzles, be sure to wear a respirator mask as well as eye protection.

Before applying any chemicals, clean out all soap chips or chunks from your spray gun’s tip by spraying some water into it while attached to an air compressor. Be sure not to touch any part of the gun that comes into contact with the chemical.

Removing spray foam insulation is a pretty straightforward process. You can likely do it yourself in just a few hours if you have the right tools. However, you must take all safety precautions before beginning any type of job like this one because there are chemicals involved in this process that could be dangerous. If you’d rather leave the work up to the experts, call your local insulation company.
