What Does Alien Seal Spray Do?

Alien Seal Spray—marketed by the website AlienSpray.com—claims to be a multipurpose sealing product designed to patch, seal, and waterproof a wide range of surfaces and materials. Based on its official review, Alien Seal Spray positions itself as an all-in-one solution for dealing with leaks, cracks, and water damage in household or outdoor settings.

The spray is described as a rubberized, flexible, self-leveling spray intended for both temporary and long-term applications. The advertised uses include sealing windows, doors, vents, roofs, pipes, and other areas commonly affected by moisture or air penetration. According to AlienSpray.com review, the spray can be painted over to match surrounding décor, suggesting aesthetic versatility alongside functional sealing.

Despite its broad utility claims, the core function of Alien Seal Spray centers on these promises:

• Forms a waterproof barrier

• Resists chipping, cracking, peeling, or drying out

• Withstands both extreme heat and cold

• Pays for itself with a single use

Important Note:

The official review at AlienSpray.com, does not offer a verified or categorized list of compatible materials (e.g., metal, plastic, wood, rubber, masonry), nor does it specify environmental limitations (e.g., moisture levels, surface prep). All claims are made in sweeping terms like "seal and protect virtually anything", without meaningful technical backup.

How Does Alien Seal Spray Work?

Understanding how Alien Seal Spray functions requires a look at the basic material science behind it, you won't find this information on the official Alien Seal Spray review. Though the specific formulation isn’t disclosed, the chemical behavior observed in similar products provides insight into how AlienSpray.com's sealer achieves its sealing properties.

1. Base Chemistry: Elastomeric Polymers

The foundation of Alien Seal Spray is almost certainly an elastomeric compound—a class of synthetic polymers known for their high elasticity. Elastomers are what give AlienSpray.com products their flexibility, allowing the spray coating to stretch, bend, and return to shape without cracking.

Common elastomers used in such sprays include:

• Styrene-butadiene rubber (SBR)

• Polyurethane (PU)

• Acrylic rubber

• Silicone elastomers

In the case of Alien Seal Spray, these polymers are likely suspended in a carrier that enables spray application and then evaporates, leaving behind a solid, flexible film.

2. Solvent Carrier or Water-Based Dispersion

For AlienSpray.com Sealer to deliver its product in sprayable form, the elastomer must be either:

• Dissolved in a volatile organic solvent (e.g., toluene or xylene), or

• Dispersed in a water-based emulsion

  
  

When Alien Seal Spray is applied, the solvent or water quickly evaporates. This triggers a process known as film formation or coalescence, where the elastomer chains settle and fuse into a continuous membrane.

This "self-leveling" effect allows Alien Seal Spray to spread out evenly across the surface, filling gaps and forming a uniform seal without needing manual smoothing.

3. Hydrophobic Behavior: Water Resistance

One of the key selling points of Alien Seal Spray and similar formulations is water resistance. This arises from the hydrophobic nature of the polymeric material.

Because elastomers are composed of nonpolar molecules, they naturally repel water. As a result, Alien Seal Spray forms a barrier that blocks both water and air, making it suitable for use in leak-prone environments like gutters, roofs, or plumbing fixtures.

4. Thermal Stability and Weather Resistance

Alien Seal Spray is marketed as resistant to extreme temperatures. In scientific terms, this likely involves the use of:

• Stabilizers and plasticizers to maintain elasticity at low temperatures

• UV inhibitors to prevent breakdown under sunlight

• Crosslinking agents to enhance high-temperature tolerance

While AlienSpray.com claims robust all-weather protection, the lack of technical documentation makes it unclear how the spray performs under prolonged exposure to freezing, high heat, or constant UV light.

5. Adhesion Promoters and Fillers

To ensure Alien Seal Spray bonds to a wide range of materials—like plastic, metal, wood, and masonry—it likely contains:

• Silane coupling agents or similar adhesion promoters

• Inert fillers like talc or calcium carbonate to improve texture, thickness, and film consistency

These additives make AlienSpray.com's formula more versatile in use, though actual bonding strength depends heavily on how well the surface is prepared before application.

Alien Seal Spray functions by delivering a flexible, rubberized polymer that forms a water- and air-tight seal after application. The process involves solvent evaporation, film formation, and chemical additives that enhance adhesion and durability. While the official review at AlienSpray.com makes several broad claims regarding weather resistance and surface compatibility, technical validation is absent, making critical evaluation essential before use in mission-critical applications.

Critical Analysis of the Claims

While the language used inn the official AlienSpray.com review is assertive and repetitive—phrases like “Patch, Seal & Waterproof Virtually Anything” appear multiple times—there’s a noticeable lack of substantiating details. The official review relies heavily on marketing buzzwords without offering measurable performance data or evidence.

1. "Waterproof Virtually Anything"

This sweeping claim from AlienSpray.com raises questions. What materials qualify as “virtually anything”? There is no material compatibility list or scope limitation provided, making it unclear whether surfaces like rubber, PVC, stucco, or untreated wood are reliably sealed by Alien Seal Spray.

2. "Withstands Extreme Cold and Heat"

Extreme weather resistance is a common claim in the sealing product category, but AlienSpray.com does not quantify what "extreme" means. Is it -20°C? +50°C? Without temperature tolerance specs, the promise feels ambiguous. Users in regions with true climatic extremes may find the product underperforms or deteriorates more quickly than expected.

3. "Seal and Protect Virtually ANYTHING"

Like the waterproofing claim, this too is an overgeneralization. In the Alien No mention is made of limitations, ideal surface prep, or environmental conditions for successful application. Alien Seal Spray might not perform equally across materials like rusted metal, rough concrete, or wet surfaces—yet the copy doesn’t mention these nuances.

4. "Won’t Chip, Crack, Dry Out, or Peel"

This is a common claim in the category of rubberized sealants. However, AlienSpray.com does not offer lab data, durability testing, or user-controlled results. The longevity of the seal remains unverified, and without independent product reviews or third-party testing, the durability claim remains untested.

5. "Pays for Itself with Just One Use"

This is a vague financial justification, implying that using Alien Seal Spray saves enough on repairs or replacements to offset its cost (~$19.99 CDN). However, such a claim is highly situational. A minor roof leak, for example, might still require professional intervention if AlienSpray.com underdelivers in sealing performance.

Pros of Alien Seal Spray

• Easy to Apply: Alien Seal Spray comes in a convenient aerosol form, making it quick to apply without the need for brushes or tools.

• Flexible After Curing: Once dried, Alien Seal Spray retains rubber-like flexibility, helping it resist cracking or breaking under stress.

• Multi-Surface Use: Alien Seal Spray is designed to bond with metal, wood, plastic, concrete, and other common surfaces, increasing its versatility.

• Waterproof Barrier: The hydrophobic properties of Alien Seal Spray make it effective for sealing out moisture and air, ideal for minor leaks.

• Temporary Emergency Fixes: Many users rely on Alien Seal Spray as a quick, short-term patch for unexpected leaks or surface damage.

Cons of Alien Seal Spray

• Durability Varies: Despite claims, Alien Seal Spray may not hold up under prolonged weather exposure or mechanical stress.

• Surface Prep Sensitive: For Alien Seal Spray to bond properly, the surface must be clean and dry—something that's not always feasible.

• Poor UV Resistance Over Time: Long-term exposure to sunlight may cause Alien Seal Spray to degrade, peel, or discolor.

• Inconsistent Thickness: Spray-on application of Alien Seal Spray can result in uneven coats, reducing sealing effectiveness in complex areas.

• Limited Penetration: Alien Seal Spray may not adequately fill deep cracks or porous materials without multiple applications.

• Difficult to Remove or Reapply: Once cured, Alien Seal Spray can be messy and difficult to remove, complicating reapplication or repairs.

• VOC Emissions: Depending on the formulation, Alien Seal Spray may emit volatile organic compounds (VOCs) during application.

• Unclear Long-Term Claims: Many durability claims made about Alien Seal Spray are not backed by independent testing or certifications.

• Cosmetic Issues: The cured finish of Alien Seal Spray might not blend well with surfaces and could require painting to match decor.

• Not Load-Bearing: Alien Seal Spray is not a substitute for structural fixes; it's only meant as a surface-level sealant.

Verdict: Should You Buy Alien Seal Spray?

Probably Not — and Here’s Why:

While Alien Seal Spray (marketed via AlienSpray.com) is heavily advertised as an all-purpose waterproof sealant, there are several critical issues that make it hard to recommend — especially when compared to more established alternatives like Gorilla Waterproof Patch & Seal Spray or Flex Seal.

Key Concerns:

• Not a New Concept: Alien Seal Spray is not introducing anything novel. Rubberized spray-on sealants have been on the market for years and are widely available from reputable brands with strong track records.

• Lack of Independent Lab Testing: There’s no third-party certification (e.g., ASTM, UL, ISO) to validate the product's waterproofing or durability claims. All information comes from promotional material without independent verification.

• Missing Safety Transparency: No VOC data, chemical safety disclosures, or environmental certifications are provided — which are typically standard for consumer-grade sealant sprays.

• Underwhelming Performance Evidence: No substantial user base or verified reviews indicate the spray version delivers as promised. By contrast, competitors have thousands of reviews and consistent performance reports.

• Marketing Over Substance: The heavy promotion and “too good to be true” claims mirror the approach used by Emson for Alien Tape — a product often criticized for overpromising.

A Glimmer of Use?

The silicone tape variant of Alien Seal (non-spray) has received moderately positive feedback, particularly for weatherproofing doors and windows. This suggests the brand isn’t entirely unreliable, but the spray version lacks proven reliability.

Better Alternatives Available

We recommend:

• Gorilla Waterproof Patch & Seal Rubberized Spray

• Flex Seal Spray Rubber Sealant

• Rust-Oleum LeakSeal Flexible Coating

• All have established reputations, broad surface compatibility, full VOC disclosures, and verified consumer feedback.

Bottom Line:

Alien Seal Spray is not worth the risk unless you’re testing it in a low-stakes situation. With no third-party backing, no review volume, and no clear chemical safety transparency, you’re better off choosing a tried-and-tested product.

Approach AlienSpray.com's claims with healthy skepticism. Do your due diligence — especially when household safety and waterproof integrity are on the line.
