Each kit contains everything you need for a complete insulation job:

• 1× Spray Foam Insulation can (26 oz / 737 g)
• 1× Foam Gun Cleaner (9.8 oz / 277 g)
• 1× Spray Insulation Foam Gun
• 2× short and 1× long foam gun nozzle tips
• 10× spray foam can nozzles
• 1× protective suit, 1× safety glasses, 12× pairs of gloves

Magic Chems produces closed-cell spray foam exclusively. Closed-cell foam is denser, water-resistant, structurally rigid, and provides higher thermal insulation per inch than open-cell. We don't offer open-cell products.

Coverage depends on the can size:

• 26 oz can → covers approximately 20 board feet at 1″ thickness
• 30 oz can → covers approximately 26 board feet at 1″ thickness

A "board foot" equals 1 sq ft at 1 inch thick. So a 30 oz can covers 26 sq ft at 1″ thick, 13 sq ft at 2″ thick, or any equivalent combination.

Magic Chems Spray Foam has an R-value of R-5.66 per inch. As a closed-cell polyurethane foam, it sits in the medium-high range for thermal insulation performance. A higher R-value means better resistance to heat transfer — practical examples: 2″ application gives R-11.32, 3″ gives R-16.98, 4″ gives R-22.64.

1. Shake the can thoroughly before use.
2. Attach the foam gun and apply evenly to the target area.
3. Let it expand to fill gaps and cracks.
4. Wait 24 hours for full cure before cutting or shaping.

Wipe excess foam with the foam cleaner before it cures — once it sets, you'll need to cut it off.

Tack-free in 5–15 minutes. Cuttable in about 1 hour. Fully cured in 24 hours. For maximum strength and insulation performance, don't sand, paint, or stress the foam until the 24-hour cure is complete.

For best results, apply when both the can and surface are between 60°F and 90°F (15°C–32°C). Cold chemicals don't mix or expand properly. If your kit has been cold, store it indoors at room temperature for at least 24 hours before use.

It bonds well to glass, MDF, wood, metal, concrete, stone, brick, granite, plaster, and most building materials — indoors and outdoors.

⚠️ Avoid polyethylene, polypropylene, silicone, Teflon, and other non-stick plastics — foam won't adhere to these.

Yes. Once fully cured (24 hours), the foam can be trimmed and painted with most water- or oil-based paints. UV light yellows and degrades exposed foam over time, so painting or covering is recommended for any visible installation.

Magic Chems spray foam does not currently include fire-retardant additives. Per most building codes, polyurethane foam must be covered with an approved thermal barrier (such as ½″ gypsum drywall) in occupied living spaces. Always check your local building code requirements before installation, and never leave foam exposed near heat sources or open flames.

No. Cured polyurethane foam has no nutritional value and isn't a food source for mold, mice, or insects. Closed-cell foam acts as a moisture and air barrier, which actually reduces mold risk. Pests find sealed walls and crawl spaces harder to penetrate after foam application.

Closed-cell foam provides moderate sound dampening, especially for blocking air-transmitted noise that travels through gaps and seams. While it's not as absorptive as open-cell foam for pure acoustic applications, it still meaningfully reduces sound transmission in walls, ceilings, and crawl spaces — particularly when paired with sound-absorbing materials like rockwool batts.

Yes, when protected from direct sunlight (under eaves, in crawl spaces, on the underside of decks). Direct UV exposure causes the foam to yellow and break down over time. For exterior use, cover the foam with paint, drywall, or appropriate sheathing.

Yes. Once fully cured, the foam can be trimmed with a serrated knife, sanded, or shaped to a smooth finish. For closed-cell foam, a coarse rasp or grinder works best.

Unopened cans have a shelf life of up to 2 years from the manufacturing date when stored at room temperature in a dry, ventilated area. Once opened, use within 30 days — the gun stays usable longer if cleaned properly between sessions.

No. Cured foam is safe around standard electrical wiring and copper or PEX plumbing. Avoid spraying directly into electrical boxes — cover them with masking tape during application.

• Around recessed lighting that isn't IC-rated (heat hazard)
• Directly on hot surfaces like furnace flues or chimneys
• On non-stick plastics (PE, PP, Teflon, silicone)
• On wet surfaces (>20% moisture)
• In sub-50°F temperatures

Multiply the area (square feet) by the desired thickness in inches, then divide by the can's coverage:

• 26 oz can: (area × thickness) ÷ 20 = cans needed
• 30 oz can: (area × thickness) ÷ 26 = cans needed

We always recommend adding a 10% buffer for waste. Most of our product pages include a built-in calculator to make this easy.

Spray it onto uncured (fresh) PU foam, wait a moment, then wipe. It dissolves wet foam off your gun, surfaces, and tools. Use it after every job to keep the gun in top condition.

After your last spray, leave the can attached and pull the trigger to expel a small amount of foam. Then thread the foam gun cleaner onto the gun and trigger it through to flush. Detach, wipe down the exterior, and store with the cleaner threaded on for next use.

No. Once foam has fully cured, only mechanical removal works — scraping, sanding, or cutting. The cleaner only dissolves uncured foam. Always clean tools immediately after use.

Yes. With proper cleaning between uses, the foam gun lasts for many cans and projects. Some users keep the gun threaded onto a partial can stored in a cool place — the foam stays usable for up to 30 days.

Yes. Our foam gun uses the standard B1 / NBS threaded fitting, so it works with most professional-grade PU foam cans on the market — not just Magic Chems. That said, we test our gun specifically with our own foam for the best dispensing experience and consistency.

CA stands for cyanoacrylate — the technical name for "super glue" or "instant glue." It bonds in seconds by reacting with surface moisture, creating a clear, strong, waterproof seal.

• Thin — water-thin. Wicks into hairline cracks, finishes wood pen turnings. Sets in 2–5 seconds. No working time.
• Medium — like olive oil. Everyday all-purpose choice for general bonding. Sets in 10–25 seconds.
• Thick — gel-like. Fills small gaps and gives 30–60 seconds of working time to position parts.

• Pen turning, knife handles, stabilizing cracks: Thin
• General woodworking, hobby models, everyday repairs: Medium
• Filling gaps, vertical surfaces, positioning parts: Thick

When in doubt, start with Medium — it covers about 80% of common use cases.

The activator (also called accelerator) instantly cures CA glue when sprayed on. It's especially useful for thick CA glue or for bonding very dry materials that don't have enough surface moisture to trigger curing on their own.

Wood, metal, glass, ceramic, leather, marble, rubber, stone, bone, hard plastics, hobby models, and most porous materials.

⚠️ Avoid polyethylene (PE), polypropylene (PP), silicone, Teflon, and other non-stick plastics — CA glue does not bond to these without a special primer.

Waterproof: Yes. Once cured, CA glue resists water and most solvents.
Heat: Tolerates moderate heat but begins to soften above 180°F (82°C). Not recommended for engine parts, ovens, or other high-heat applications.

Store unopened bottles in a cool, dry place. Many users keep unopened bottles in the freezer to extend shelf life — let them return to room temperature before opening to avoid condensation. Once opened, store at room temperature with the cap tightly sealed. Avoid humid environments.

• Unopened, room temperature: up to 2 years from manufacturing
• Unopened, frozen: even longer storage life
• Opened: 1–3 months at peak performance — store in a cool, dry place to extend usable life

The most common cause is bone-dry material with no surface moisture. CA glue cures by reacting with humidity. Try lightly misting one surface before applying, using the activator on the other surface, or switching from thin to medium viscosity for porous materials.

Don't panic and don't pull. Soak the area in warm soapy water for 5–10 minutes, then gently roll the skin apart. Acetone (regular nail polish remover) also dissolves cured CA glue. For eyes or large areas, contact a doctor immediately.

Yes. Once cured (within 60 seconds with activator, or a few minutes without), CA glue can be sanded, drilled, machined, or finished. Many woodturners use thin CA + activator as a glossy finish on pens and small turnings.

CA glue is not certified for direct food contact. Don't use it on dishware, cutting boards, or anything that touches food.

• Always work in a well-ventilated area — open windows, use fans, or work outdoors when possible.
• Wear the included PPE (suit, glasses, gloves); for extended use, add a respirator with organic vapor cartridges.
• Avoid direct skin and eye contact with uncured spray foam — it bonds aggressively.
• Keep away from open flames during application — propellants are flammable.
• Always read the safety data sheet (SDS) on each product before use.

Safety Data Sheets are available on request. Email info@magicchems.com with the product name and we'll send you the SDS PDF — usually within one business day. Contractors and bulk customers can request a full SDS package for all our chemicals.

Many of our products — including the foam gun cleaner — are formulated with eco-conscious materials and processes. Cured polyurethane foam is inert and stable but not biodegradable; dispose of it according to local regulations. Check individual product pages for specifics.

Spray foam cans: If unused and pressurized, take to a household hazardous waste facility — most municipalities accept them for free. CA glue: Allow small amounts to cure fully, then dispose of with regular trash. Unopened bottles should go to a hazardous waste facility. Foam gun cleaner: Treat as solvent — hazardous waste facility. Never pour any of these down drains or into the regular trash without checking your local regulations first.
