Heelos Asphalt Crack Filler,2Pack High Elasticity Driveway Crack Filler,Self Leveling Waterproof Asphalt Crack Sealant Repair Sealer for Blacktop Concrete Cement Driveway,Walkway, Road,Patio

Introduction

Small cracks in asphalt and concrete are rarely static—they widen with traffic, wick in water, and split open during freeze–thaw cycles. I tested the Heelos crack filler on a mix of typical problem areas: a couple of narrow, meandering seams on an older asphalt driveway, a wider settlement crack at the garage apron, and a hairline split across a concrete patio slab. Over several weeks of spring rain and early summer heat, I paid close attention to application ease, curing, appearance, and durability under foot and vehicle traffic. It’s not a miracle in a pouch, but used thoughtfully it’s a reliable, DIY‑friendly way to stop water intrusion and arrest crack growth.

What you get and how it’s packaged

The kit includes two 500 g squeeze pouches (about 26 fl oz total), each with a twist cap and a tapered nozzle, plus a small brush and a pair of gloves. The pouches are convenient—no caulk gun required—and the nozzle reaches into narrow cracks cleanly. For small to mid‑sized jobs, the packaging is more helpful than gimmicky. If you’re tackling a long driveway network of cracks, you’ll wish for a larger container or a gun‑grade option, but for a typical suburban driveway and a few slab seams, two pouches are a reasonable starting point.

Application and workflow

Prep matters. I blew out the cracks with compressed air, brushed out grit, and cut back a couple sections with a crack chaser to create a consistent channel. The filler has a flowable, gel‑like consistency that self‑levels. In practice, that means you can lay a bead slightly proud of the surface and it will settle flush within a few minutes. On flat areas, this is great. On sloped or crowned surfaces, the product can run; in those spots I applied it in thinner passes with a few minutes between lifts to avoid sag.

The included brush is handy for feathering edges and nudging material into irregular corners, but it also smears a glossy film on either side if you overwork it. Masking with painter’s tape along crisp edges helped me keep the finish tidy, especially on concrete steps and the garage threshold.

Deep cracks need multiple passes. Anything approaching the depth of a pencil eraser benefited from two or three rounds, with at least an hour between to let the previous lift settle. For wider gaps, a foam backer rod is worth using so you’re not dumping filler into a bottomless joint. It’s black and opaque, so you get good visual feedback as it fills.

Cure time and traffic

Skin time was under an hour in mild weather, and it resisted dust pickup after that. Full cure took closer to 36 hours at 65–75°F for me. The manufacturer says 24–48 hours, which aligns with what I saw. I kept vehicles off the driveway for two days. After curing, the seal feels like a firm rubber—compressible under a fingernail but not tacky—exactly what you want in a joint that needs to flex with movement and temperature swings.

Adhesion and flexibility

Adhesion on clean asphalt was very good. I couldn’t lift an edge with a putty knife without cutting into the material. On smooth, troweled concrete, it also bonded well, but the one area that gave me trouble was a dusty section at the garage apron that I didn’t prep as carefully; a small section debonded at the surface and needed a redo. The takeaway: remove dust thoroughly, and lightly rough smooth concrete for best results.

The cured material retains some elasticity. I haven’t seen any edge cracking, even after a week of daytime heat and cool evenings. That flex makes me more confident about its ability to survive freeze–thaw cycles without pulling away.

Waterproofing and weather handling

This is where the Heelos filler earns its keep. After several heavy rains, the garage slab crack that used to weep stayed dry. Water beads on the surface and doesn’t wick into the joint. On a sun‑exposed stretch of asphalt, it hasn’t chalked or faded yet; the black is still deep. I’m not seeing any UV‑induced brittleness so far, and it shrugged off a few days of 90°F heat without turning soft.

Appearance and finish

The filler cures to a deep, uniform black with a noticeable sheen. On blacktop, it blends reasonably well once the surrounding asphalt is clean, though the gloss line is visible at certain angles. On older, lighter‑colored concrete, the contrast is stark. If you’re aiming for a seamless visual match on concrete, this isn’t the product that disappears—functionally it’s sound, cosmetically it reads as a repaired joint.

A separate consideration is topcoating. I tested a film‑forming acrylic sealer over a small cured section and found that it struggled to bite into the glossy surface. A light scuff with 180‑grit and a solvent wipe improved adhesion, but I would strongly recommend doing a small patch test if your plan includes sealing or painting over the repairs. In general, treat this as a final joint sealant rather than a paintable patch.

Coverage and value

Coverage varies wildly with crack width and depth, but one pouch handled a handful of hairlines and about 10–12 linear feet of 1/8‑ to 1/4‑inch cracks in my case, with some left over. Two pouches are adequate for a typical residential touch‑up. If your driveway looks like a spiderweb, budget for more and consider backer rod where possible to avoid wasting material in deep voids.

Mess and cleanup

The nozzle allows neat placement, but because the filler is flowable, it will find the low side. Taping and working in smaller sections helps. The nozzle can clog if you let material sit in it for long; I kept a nail handy to cap it between passes. The included gloves are not optional—this is sticky before it skins. I treated all disposable tools as indeed disposable; cleanup with solvents is possible but not worth the effort for the brush.

Strengths

• User‑friendly packaging: Squeeze pouches with nozzles make it accessible for DIYers.
• Self‑leveling, flexible seal: Flows into irregular cracks and cures with elasticity to handle movement.
• Solid weather performance: Waterproof, resists rain and sun, and holds up under tire traffic.
• Good adhesion on properly prepped asphalt and concrete.

Limitations

• Glossy, very black finish: Blends on blacktop, stands out on light concrete, and can telegraph under some topcoats.
• Flowable consistency: Can run on slopes and requires multi‑lift applications for deep or wide joints.
• Not ideal for large jobs: Pouches are convenient but become inefficient for extensive crack networks.
• Surface prep is critical: Dusty or overly smooth concrete can hinder adhesion.

Tips for best results

• Prep thoroughly: Vacuum, blow, and brush out dust and debris; lightly rough smooth concrete.
• Control the flow: Tape edges on visible surfaces and apply in thin lifts on slopes.
• Use backer rod: For cracks deeper than 1/2 inch, add a backer rod to reduce material use and improve joint performance.
• Mind the weather: Apply in dry conditions and protect from rain for at least 24–48 hours.
• Test topcoats: If you plan to seal or paint over it, scuff a cured test area and check compatibility before committing.

Bottom line

The Heelos crack filler is a straightforward, effective way to seal and stabilize cracks in asphalt and concrete without specialized tools. Its self‑leveling behavior, flexible cure, and weather resistance make it a strong match for driveways, garage aprons, and patio slabs where the primary goal is to stop water intrusion and prevent further cracking. The tradeoffs are mostly aesthetic: a glossy, jet‑black finish that blends with blacktop but stands out on concrete, and some sensitivity to topcoat adhesion unless you prep the cured surface.

I recommend this tool for homeowners who prioritize function over an invisible repair and need a dependable, DIY‑friendly sealant for small to medium crack repairs. If a near‑perfect cosmetic match on light concrete or guaranteed topcoat compatibility is critical, you may want to look for a color‑matched, paintable crack repair system instead. For everything else—keeping water out, preserving your pavement, and buying yourself years before the next big resurfacing—the Heelos filler does the job well.
