| Frequently Asked Questions
How do I get foam off of my hands?
If the foam has not cured or hardened, use acetone or fingernail polish remover (with acetone). If the foam has hardened, there is no solvent that will remove it. It will not harm your skin and will wear off in several days. To remove cured foam from skin, use a pumice stone (available at most drug stores) and warm, soapy water. Then apply petroleum jelly to soften your skin.
How do I get foam off the side of my house?
If the foam has not cured or hardened, use acetone or fingernail polish remover (with acetone). There is no solvent that will remove cured polyurethane foam. Remove as much as possible with a dull scraper or a hacksaw blade and then try scrubbing the remaining film with a non-abrasive cleaner. If that does not work, gradually move up to more aggressive means including sanding, sandblasting and repainting.
Warning: When using acetone on surfaces such as sidings, always test a hidden section of the surface to make sure that the acetone does not discolor the surface.
How much foam is in a can of WIN FOAM™?
The theoretical yield of a can of WIN FOAM is measured in lineal feet of a 3/8”– 1/2” diameter bead. One 12 oz. can of WIN FOAM has about 250 lineal feet. One 16 oz. can has about 335 feet. One 20 oz. can has about 420 feet. One 6 oz. can yields approximately 120 feet.
Can I insulate my walls with WIN FOAM?
WIN FOAM sealants use moisture in the air to cure. It is designed to fill small cracks and gaps. The foam does not cure properly if it is used to fill large voids unless it is put down in layers and allowed to cure before the next layer is applied. Do not use WIN FOAM to fill enclosed voids such as behind drywall or under tub surrounds.
Can I store WIN FOAM if I don’t use the whole can?
WIN FOAM straw foam will seal itself shut if left to sit for more than 2 hours after its last use. Insert a pipe cleaner sprayed with oil lubricant may prolong the life of the product. Plan ahead, identify and list all possible applications before opening can.
What are the temperature limitations when using WIN FOAM?
The contents of the WIN FOAM can should be as close to room temperature as possible when dispensed.
Can I use WIN FOAM to air-seal my electrical receptacles?
WIN FOAM can be used around and behind electrical boxes and insulated wires, but should never be used inside a box where it may be exposed to bare copper wires.
How are latex products different from WIN FOAM?
There are two key differences between latex foam and WIN FOAM, which is a polyurethane foam:
- Latex foams are typically “open celled” and, as a result, can take on water. In fact, the same properties that allow you to wash latex foam off your hands with water also mean that the cured foam can absorb water. This can cause wood rot or deterioration in areas where wet latex foam is next to wood, such as a window frame. In contrast, WIN FOAM is closed-cell foam. It forms a water-resistant outer coating when cured.
- Latex foam does not expand. WIN FOAM expands to thoroughly fill all voids and cavities making it an ideal air-sealant.
Does WIN FOAM come in different colors?
WIN FOAM Gaps & Cracks and WIN FOAM Big Gap Filler are both cream color. WIN FOAM Window & Door is yellow. All may be painted after they are fully cured.
Can mice, insects or rodents chew through WIN FOAM?
Mice, raccoons and large pests, if determined enough, can chew though many materials, including WIN FOAM. When a barrier is needed for large pests, it is recommended a wire mesh be installed and WIN FOAM applied generously on both sides of the mesh. For insects and bugs, WIN FOAM alone typically serves as an effective barrier.
Are WIN FOAM products ozone friendly?
WIN FOAM does not contribute to the depletion of ozone.
Can WIN FOAM be used outdoors?
Yes, WIN FOAM can be used outdoors. However, cured foam will discolor if exposed to ultraviolet light. Paint or coat foam for best results in outdoor applications.
Does WIN FOAM contain formaldehyde?
No, WIN FOAM does not contain any formaldehyde.
What is the difference between WIN FOAM and WIN FOAM PRO products?
There are three key differences between WIN FOAM and WIN FOAM products:
- WIN FOAM uses a straw dispenser; WIN FOAM Pro can be used with a gun tool applicator to dispense foam.
- Size of cans.
- Temperature dispensing range.
- WIN FOAM is cream colored.
- WIN FOAM PRO Gaps & Cracks is orange colored
What precautions should I take when using WIN FOAM?
-
Prevent skin and eye contact by wearing gloves and protective eyewear.
-
Protect area near application with a drop cloth or newspaper
-
Practice dispensing foam on newspaper before begining your application.
-
Do not apply foam while smoking or near an open flame. Foam is flammable until cured.
How long does WIN FOAM take to cure?
WIN FOAM is tack free within approximately 15 minutes and cures fully in eight hours.
What if I overfill a void?
Wait until the foam cures and trim excess with a sharp knife or serrated blade.
What surfaces/substances will WIN FOAM not bond to?
WIN FOAM will not bond to Teflon®, paste wax and some polyethylene plastics.
Will an unused can of WIN FOAM ever expire?
Yes, that is why there is an expiration date printed on the bottom of each can of WIN FOAM. If you attempt to use a can after the expiration date and the product will not dispense, dispose of the can. Do not try to activate the can by pushing hard on the dispenser or puncturing the valve. These actions will likely result in an uncontrollable venting of the product that is very difficult to clean up.
