How to Use Slow Curing Liquid Foam
Liquid foam is a substance formed by trapping gaseous bubbles. It is used for insulation and is available in spray containers and pressure sprayed product. It expands and hardens; conforms to the shape of the cavity and seals it thoroughly as the chemical mixture cures. Slow curing liquid foam is designed to flow over barrier before it expands and cures. It is used to fill empty wall cavities in buildings. Liquid foam insulation products forms air barrier that eliminates caulking, taping joints, house-wraps and vapor barriers; thus, reducing the cost associated with weather proofing the home. When used in new architecture, it considerably reduces construction time and eliminates the number of specialized contractors and saves money. Spray foam is employed to insulate foundations, walls, roofs, entry and overhead garage doors, pipes, tanks, basement slabs and slab-on-grade floor. Additionally, when sprayed in floor and wall cavities provide insulation and soundproofing. Foam can be locked in concrete walls via pouring and injecting liquid foam into the hollow block cores. Alternatively, concrete blocks can be manufactured to accommodate foam inserts. Insulating Concrete Forms (ICF's) are rigid foam panels and blocks that serves as a permanent solution for concrete walls and foundations. When using slow curing liquid foam it's important to strictly adhere to the following pointers for safe usage.
Step1: Prepare the Slow Curing Liquid Foam Insulation Kit
The tanks must be maintained between 75 and 85 degrees Fahrenheit for the slow curing liquid foam to work perfectly. Use the temperature strip (supplied in the kit) to gauge and tune their temperature levels to the benchmark.
Use the wrench to attach the hoses to the two spray foam tanks. Twist the valves to open the chemical tanks. Finally, clip the nozzle onto the gun.
Step 2: Using Slow Curing Liquid Foam
Stand at a distance of 18-24 inches from the surface to be foamed. Spray 1- inch bead of slow liquid curing foam around the perimeter of the desired area. With back-and-forth motion fill the area. Spray it with thin strokes; it will rise up to one inch. Allow the foam to cure for 20 minutes.
Please Note: If you want a higher r-value, spray another thin coat.
Step 3: Examine the Foam Coverage
Inspect each sprayed section for gaps and quality of foam coverage. In either of the cases spray another coat if required.
Step 4: Remove Protruding Foam Studs
Excessive foam inhibits the correct and even drying of installation. Use foam saw to eliminate the foam stud that oozes out of the foamed surface upon curing.
Tips and Warnings
- Cover exposed areas like electrical outlets, doors and windows with masking tape or plastic to prevent any damage caused to them during the process.
- Slowly apply the spray for smooth and effective procedure; allowing foam to expand prior additional application, lest over-filling will cause loss of time, effort and money.
- Wear protective clothing and mask; safety glasses and rubber gloves while working. Keep kids and pets away from the work area.
