YallCanDiy Closed Cell Spray Foam Insulation Kit (18 Pack) - DIY

In this review of the YallCanDiy Closed Cell Spray Foam Insulation Kit (18 Pack) the bottom line is simple: this kit is aimed at homeowners and DIYers who need a ready-to-use, high-capacity solution for sealing gaps, insulating and reducing noise. The reviewer found the full kit-18 expanding foam cans plus a Teflon coated foam gun, cleaner and protective gear-well suited to medium to large sealing jobs. The closed-cell dominant formula provides lasting thermal insulation and moisture resistance, which makes it a practical choice for attic, window and perimeter sealing projects.

Key Features

• Complete kit: Includes 18 foam cans, a Teflon coated PU foam gun and cleaner so users can begin multiple projects without sourcing extra parts.
• High capacity cans: Each can holds 25.36 fl oz (750 ml), providing substantial expansion to fill gaps and cracks efficiently.
• Closed-cell structure: With roughly 80% closed-cell content, the foam offers superior thermal insulation and improved moisture resistance over open-cell alternatives.
• Sound reduction: The expanding foam acts as a sound barrier, helping to lower airborne noise when used around windows, doors and wall penetrations.
• Durable seal: The foam expands to form a tight seal that resists drafts, pests and weathering for long-term energy savings.
• Included safety gear: Gloves, safety glasses and a suit coverall are supplied to support safe application during multi-can use.

Who It's For

The kit suits homeowners, small contractors and serious DIYers tackling attic insulation, window and door sealing, pipe insulation and general gap filling around a house. It is particularly useful for projects where multiple cans are needed right away and where a robust, moisture-resistant seal is desired.

Those working in very cold environments or needing the fastest possible cure in suboptimal conditions should exercise caution; the product performs best between 60F and 90F (15C and 32C) and cures faster with higher humidity. Users needing only a single small repair might prefer a single-can option rather than this large 18-pack.

Pros & Cons

Pros

• Comprehensive kit reduces trips to the supply store by including gun, cleaner and application accessories.
• High-volume cans and strong expansion cover cracks and cavities effectively, accelerating project completion.
• Predominantly closed-cell formulation improves thermal performance and resists moisture long term.
• Included PPE and cleaner help maintain the gun and enable safer, cleaner use across many cans.

Cons

• Best results require ambient temperatures of 60F to 90F; colder jobs may need acclimation or alternative products.
• The kit is large and intended for multiple uses, so it may be excessive for a single small repair.

Our Verdict

The YallCanDiy 18-pack is a strong value for anyone who needs multiple cans and a ready-to-use foam gun setup; it pairs high-capacity cans with a mostly closed-cell foam that insulates, blocks moisture and reduces noise. For larger DIY sealing and insulating tasks it saves time and guesswork, though single-repair users may find the pack larger than necessary.

Frequently Asked Questions

How many projects will the kit cover?
The 18 cans are intended for multiple medium to large sealing jobs; exact coverage depends on gap size and application technique.

Is the foam moisture resistant?
Yes, the predominantly closed-cell structure improves moisture resistance compared with open-cell foam.

What temperature is best for application?
Apply between 60F and 90F (15C and 32C) for optimum expansion and curing; higher humidity speeds cure.
