Cold Weather Shipping 

Secure Set Spray Foam Kits

Secure Set Spray Foam performs best when shipped and applied under safe temperature conditions. Because spray foam is sensitive to freezing, exposure to below-freezing temperatures during transit can permanently damage the product and impact performance.

When winter weather exists  in Oklahoma and along several common shipping routes, we will temporarily hold spray foam shipments until temperatures are consistently above freezing.

Shipping Options

Secure Set Spray Foam Kits

• Shipments will be released as soon as temperatures rise above freezing along the full delivery route
• Ordering now ensures priority shipment when conditions improve

Any customer whose order is placed on temporary Weather Hold will be notified by email.  The email will include a link to a Cold Weather Shipping Waiver form for customers who want to request immediate shipment.  

For product protection, spray foam kits cannot ship during freezing conditions without a completed waiver.

We recommend a 3/8" diameter masonry bit.  You'll want to have one long enough to drill through your concrete slab. You'll also need enough length to drill through the thickness of hardened foam for additional lift. Some customers have reported slab thicknesses between 3" and 11", so having a longer bit ready will save you time.

Normal shelf life is up to 12 months from date of manufacture. Shelf life may be decreased when exposed to temperatures over 110℉. Cooler storage areas will ensure proper shelf life.

The actual expiration date is stamped on the tanks and shipping box.  For best results, we recommend ordering the product 2 to 8 weeks before your expected project start.  

Once you drill through the concrete slab, you can use a wire with a 90 degree bend in the end you insert.  This allows you to "grab" the bottom of the slab first to measure the slab thickness.  Then, you will reinsert the wire until it hits ground and measure the difference.  Keep in mind the height of the void will vary, so you'll want to take several measurements.  Using a hammer, you can tap the concrete surface to determine the width and length of the void.  The hammer will sound different over solid areas. Check our videos for examples. Another option is to use a borescope/endoscope to visually inspect the void.  We recommend buying one with dual-lens technology, providing multiple viewing angles. 

Using extensions tubes can decrease the yield of the product. Testing with a 50' extension significantly reduced the volume of foam and increased the density. Even 10' extensions have been found to reduce the yield. It is difficult to estimate the reduced yield due to variables including product, ground, and ambient temperatures.

Secure Set Spray Foam can be used as an insulation layer.  It has an R value of 6 per 1" of thickness.  Two 1" layers would provide an R value of 12. 

An order for Secure Set is normally processed and shipped the same day it is received, if the order arrives before 2pm Central Time (Monday thru Friday). Transit times vary from 1 to 4 days depending on the destination address. All shipments originate from Oklahoma. Most shipments arrive in 3 days or less.

GRA Services has not tested Secure Set Extra Heavy Duty Spray Foam for lifting structures, support walls, or footings.  Many customers have used the product for those projects and reported great success.  

Do NOT use tools.  Doing this will void warranty.  Contact GRA Support for assistance. 

If only one side of your spray gun is dispensing (usually the red “A” side), the issue is almost always due to temperature, clogging, or crystallization in the chemical or nozzle. Follow these troubleshooting steps in order:

1. Check temperatures:

   • Both tanks, the gun, and hoses must be between 70°F and 90°F (21°C–32°C) during use.

   • If it’s cooler than this, bring the entire kit indoors or warm the tanks gently before spraying again.

   • Never use open flames or direct heat.

2. Check for kinks or restrictions:

   • Inspect both hoses. Any sharp bends or flattened areas can block flow.

   • Straighten or reposition hoses as needed.

3. Purge the gun:

   • Remove the nozzle completely.

   • Aim the gun into a cardboard waste box, not the product carton.

   • Pull the trigger for 5–10 seconds to confirm that two even, side-by-side streams are coming out of the gun.

   • If one side sputters or doesn’t flow, continue to Step 4.

4. Warm and re-lubricate:

   • Apply petroleum jelly (lubricant) to the O-ring and the face of the gun.

   • Let the tanks sit in a warm area (70–90°F) for at least 30–60 minutes, then retest.

   • Crystallization in the red (A) side is more common if the kit has sat unused for several weeks.

5. Check the nozzle:

   • If both sides dispense properly during purging, attach a new nozzle.

   • Make sure the black internal mixer is still inside the nozzle before use.

   • Do not reuse or clean old nozzles — always discard them once foam begins to harden.

6. Still not spraying evenly?

   • Close the valves and contact GRA Services Support at 405-672-8885 before attempting to force valves or disassemble the gun.

   • Using tools on valves or fittings may void your warranty.

Yes — your spray gun and hose assembly can be reused for up to 30 days after first use, provided the system is properly shut down, sealed, and stored according to the instructions. Follow these steps carefully to make sure the gun, hoses, and valves stay functional for the next use:

1. Close and secure the system after spraying

• Turn both cylinder valves clockwise to the closed position.

• Do not drain the hoses. They must stay full to keep air and moisture out.

• Push the trigger safety forward into the locked position.

2. Protect the gun with lubricant and nozzle

• Remove the used nozzle but do not discard it.

• Wipe any liquid or foam residue off the gun face with a clean, dry cloth.

• Apply a generous amount of petroleum jelly (lubricant) to:

  • The O-ring, and

  • The entire face of the gun, covering the small piston holes.

• Reattach the used, hardened nozzle. This acts as a protective cap to seal out air and moisture.

3. Storage between uses

• Store the kit indoors at 60–90°F (16–32°C) in a dry area, away from direct sunlight, freezing temperatures, or open flames.

• Do not lay tanks on their sides or upside down. Keep them upright in the shipping box.

• If the kit has not been used for more than 7 days, remove the old nozzle,
  dispense a small amount of foam into a waste box, wipe clean, re-lubricate,
  and reseal with the same nozzle.

4. When reusing the kit

• Before spraying again, confirm both tanks and hoses are warmed to 70–90°F (21–32°C).

• Gently rock or roll the tanks if they’ve been sitting for more than 2 months to remix settled chemicals.

• Always install a new nozzle for each new spray session.

• Spray a small test amount into a cardboard box to confirm that the foam color is uniform and mixes evenly.

5. Important precautions

• Never attempt to clean or flush hoses with solvents or air pressure.

• Never remove hoses from the tanks once connected — this breaks the factory seal and voids the warranty.

• If one side of the gun doesn’t spray during reuse, follow the troubleshooting guide for uneven spray

Proper storage is critical to protect the chemicals, gun, and hoses so your kit can be reused safely for up to 30 days after it’s first opened. Follow these steps immediately after spraying and whenever the kit will sit unused for more than a few hours.

1. Close and secure both tanks

• Turn both cylinder valves clockwise until closed.

• Do not drain the hoses — keeping them full prevents air and moisture from entering the system.

• Push the trigger safety forward into the locked position.

2. Clean and protect the gun

• Remove the used nozzle, but do not throw it away.

• Wipe the gun face and barrel clean with a dry cloth (do not use solvent).

• Apply a generous coating of petroleum jelly (lubricant) to:

  • The O-ring, and

  • The entire face of the gun, including the small piston holes.

• Reattach the used, hardened nozzle.
  This acts as a seal to keep the gun face from drying out and to block air and moisture.

3. Choose a proper storage location

• Store the entire kit indoors at 60–90°F (16–32°C) in a dry area.

• Keep the tanks upright in their original box.

• Do not store the kit sideways, upside down, outdoors, or in direct sunlight.

• Keep away from freezing conditions, heaters, or open flames.

4. Maintenance during downtime

• If the kit is not used for more than 7 days, perform this quick check:

  1. Remove the hardened nozzle.

  2. Dispense a small amount of foam into a waste cardboard box to confirm both sides flow evenly.

  3. Wipe the gun face clean.

  4. Reapply lubricant and reinstall the same hardened nozzle.

• This helps keep the valves and hoses primed for the next use.

5. Before using the kit again

• Make sure the tanks, gun, and hoses are warmed to 70–90°F (21–32°C) before spraying.

• If the kit has been stored for more than 2 months, gently rock or roll the tanks to remix the contents before use.

• Attach a new mixing nozzle and perform a test spray into a cardboard box to confirm the foam color and mix quality.

6. Safety and warranty notes

• Never attempt to disconnect hoses from the tanks once installed — this breaks the factory seal and voids the warranty.

• Do not use tools to open stuck valves. If valves will not open by hand, contact GRA Services Support at 405-672-8885 for guidance.

• Always store the kit where children and pets cannot access it.

If your foam is runny, discolored, or stays sticky after spraying, it means the two chemical components (A and B) are not mixing in the correct ratio. This can happen for several reasons, usually related to temperature, nozzle issues, or uneven flow between the two tanks.

Follow these steps to identify and fix the problem before wasting more material.

1. Check temperatures first

• Both tanks, hoses, and the spray gun must be between 70°F and 90°F (21°C–32°C) before and during use.

• If the chemicals are too cold, the red (A) side can crystallize or thicken, blocking flow and causing poor mixing.

• Bring the kit indoors to warm up for several hours or set it in a controlled area — never use direct heat or open flames.

2. Make sure the tanks are upright and secure

• Always spray with the tanks in their box and standing upright.

• If tanks are tipped, laid sideways, or upside down, the system can draw only propellant gas from one side, resulting in uneven flow and uncured foam.

3. Inspect hoses for kinks or restrictions

• Straighten any bent or flattened hose sections.

• A partial blockage on either side can prevent even dispensing.

4. Purge the gun and test flow

1. Remove the nozzle completely.

2. Aim the gun into a cardboard waste box (never the product carton).

3. Pull the trigger and verify that two even, steady streams of liquid come out — one from each side of the gun face.

4. If one side sputters or flows less, stop and check temperature again or warm the tanks further.

5. Wipe the gun face clean before attaching a new nozzle.

5. Inspect and replace the nozzle

• Always install a new mixing nozzle for each spray session.

• Make sure the black internal mixer is still inside the nozzle — this small insert blends the two chemicals.

• Never remove or reuse nozzles after the foam starts curing; a partially blocked nozzle will cause uneven mix or sticky foam.

6. Confirm proper spray technique

• Apply foam in thin layers (up to 2 inches) and allow each layer to expand and cool before adding more.

• Avoid continuous spraying longer than one minute — long spray times can cause the canisters to chill and pressure to drop, affecting the mix ratio.

• If you see frost forming on the fittings or hoses, stop and allow the system to warm back up.

7. Check for chemical age or settling

• If the kit has been stored for more than two months, gently rock or roll the tanks before use to remix any settled material.

• Expired or old product may also result in sticky or uneven foam — check the expiration date on the carton before spraying.

8. If the problem continues

• Stop spraying immediately and contact GRA Services Support at 405-672-8885.

• Do not attempt to force valves, disconnect hoses, or use tools on the fittings — this can damage the system and void the warranty.

• A support technician can help determine whether the issue is due to storage, temperature, or product condition.

Temperature is one of the most important factors for getting proper foam mix and performance.
Both the red (A) and white (B) canisters must be warmed to 70–90°F (21–32°C) before spraying. If the chemicals are too cold, the foam will spray unevenly, appear discolored, or remain sticky instead of curing properly.

1. Ideal temperature range

• Before and during spraying:

  • Chemical temperature: 70–90°F (21–32°C)

  • Ambient air temperature: 60–90°F (16–32°C)

  • Substrate (surface being sprayed or injected): 60–90°F (16–32°C)

• Temperatures outside these ranges can cause pressure imbalance or improper mixing, resulting in poor foam quality.

2. How to check if tanks are warm enough

• The tanks should feel slightly warm to the touch, not cool or cold.

• When you gently shake a canister, you should hear and feel the liquid moving freely inside.

• During the first test spray into a waste cardboard box, the foam should:

  • Come out smoothly and evenly from both sides

  • Turn off-white within a few seconds

  • Be tack-free in 30–60 seconds

If the spray sputters, the color looks uneven, or the foam stays wet or sticky, your canisters are too cold.

3. How to warm your canisters safely

• Bring them indoors at least 24 hours before use if stored in a cold location.

• Set them in a warm (not hot) room, ideally 68–75°F (20–24°C), and allow them to warm slowly.

• For faster warming:

  • Keep tanks in their original box and place the box near a safe heat source such as a space heater or radiator — not closer than 3–4 feet away.

  • Rotate or gently rock the tanks every 15–20 minutes to distribute heat evenly.

• Never use open flames, hot water, or direct heating devices on the tanks. Doing so can damage the valves or cause overpressure.

4. Cold weather tip

If ambient temperatures are below 60°F (16°C):

• Warm both tanks to 80–90°F (27–32°C) before starting.

• Keep them inside the shipping box during spraying to retain heat longer.

• If you’re working outside, rotate tanks between the spray area and a heated space.

• Use short spray intervals (10–15 seconds at a time) to avoid chilling the canisters.

5. Signs your tanks are too cold

• Foam comes out unevenly or in separate colored streams.

• The red (A) side stops flowing entirely.

• Spray pressure drops, or foam sputters from the nozzle.

• The gun or hoses feel icy or show frost buildup.

If any of these occur, stop spraying immediately and warm the tanks back up before continuing.

Secure Set Spray Foam kits include two types of mixing nozzles:

• Clear (Conical) – Creates a stream-style flow for direct injection and lifting applications.

• Yellow (Fan) – Produces a fanning spray pattern for surface coverage or side-access applications.

Both are mixing nozzles that blend the A-side and B-side chemicals as foam exits the gun.
Do not remove the small black insert inside the nozzle — that is the mixer and is required for proper foam expansion.

Spray foam kits ship under hazardous materials (Hazmat) regulations because the pressurized canisters cannot be safely returned once shipped.
For safety and compliance reasons, no returns or refunds are allowed on spray foam kits after they leave our warehouse.

Note: The product itself is not toxic or environmentally hazardous — it’s classified as Hazmat only because it’s shipped in pressurized containers.

Wrapping 5–7 turns of black electrical tape around the tube or nozzle ensures a snug seal in the drilled hole.
This prevents foam blowback, which can clog the gun, hoses, or mixing nozzle.
The tape also helps maintain consistent pressure and reduces waste from leakage during application.

After spraying:

1. Close the valves on both canisters.

2. Remove the used nozzle and apply petroleum jelly over the face of the gun and the O-ring, covering the small piston holes.

3. Attach a hardened-off nozzle to protect the gun from air exposure and crystallization.

This step is essential to prevent clogging and extend the life of the applicator.

Yes. Temperature plays a major role in foam performance.

• Cold weather: Product may expand slowly or incompletely; always warm kits to the recommended range before use.  See our temperature guide for full details. 

• Hot weather: Product can crystallize, especially the red (A-side) component, if exposed to air or excessive heat.
