What You'll Learn
Why cracks get filled at all, how cold-pour differs from hot-pour, which cold products fit which crack, and the clean-to-dry sequence.
Why Crack Sealing Matters
Open cracks let water into the base. The article treats that as the path to potholes, and crack filling plus sealcoating as the preservation pair.
What Is Cold-Pour Crack Filling and Sealing?
Cold-pour is an unheated, usually clay-filled polymer or asphalt emulsion placed from the pail. The article uses filling and sealing loosely for this work and aims it at lots and driveways.
What Is Hot-Pour Crack Filling and Sealing?
Hot-pour is a rubberized block melted in an oil-jacketed kettle. Fast set makes it the road and highway tool. The article still recommends cold-pour on lots when a clean line and a sealcoat schedule matter.
Featured Cold-Pour Crack Fillers and Sealants
Each product below is for a different crack width or distress. They are not one material in different cans.
TruFlex Rubberized Crack Sealant
A highly rubberized cold sealant for asphalt and concrete. Used straight for ordinary cracks, or with sand when the crack is wide or the area is alligatored. The article says it can go on slightly damp cracks because it is water-based.
TruFlex application notes
Pour from a banding machine, a cold-pour unit, or by hand. Sand thickens it for wider distress. Read the source before you change the mix.
Pourable Crack Sealant
The general cold filler for cracks up to about a half inch. Rubberized so it can move with temperature.
Pourable application notes
Pour, squeegee flush, and let it dry before traffic. The source has the dry-time conditions.
Trowel Grade Crack Filler
A thicker mineral-filled grade for cracks up to about an inch and for voids a pourable filler will not stay in.
Trowel-grade application notes
Pack it with a trowel, knife, or scraper. Set time depends on thickness and weather. Do not treat it like a thin pour.
GatorPave
A cold polymer-modified patch for alligatored areas, squeegeed or troweled before sealcoating. It is a surface repair, not a crack line.
GatorPave application notes
On alligator cracking, place it and optionally sand the surface so the later sealer bonds. On cracks, trowel or squeegee it flush.
Acrylic Crack Filler
An elastomeric acrylic for narrow cracks and alligator areas, left smooth so a later sealcoat can go over it.
Acrylic application notes
Fill, squeegee level, and let it dry before traffic. The article presents it as compatible with follow-on treatments.
How to Crack Fill: Step-by-Step Process
The sequence is the same across these cold products: clean, prepare, place, optional sand, dry, clean tools.
1. Clean the Cracks Thoroughly
Debris blocks the bond. The article mentions a wire-brush edger for dirt and vegetation before any filler goes in.
2. Prepare the Material
These fillers are used as they come, without heat. Read the SDS and TDS first. A squeeze jug only needs the tip cut to the opening you want.
3. Choose an Application Method
A banding machine lays a consistent band. A cold-pour pump feeds a wand from a pail or drum. Hand pouring is the small-job path.
4. Optional Step: Add Sand When Needed
Some products, TruFlex included, accept sand for a thicker repair on wide or broken areas. Only do that where the product sheet allows it.
5. Allow Material to Dry Properly
The article says the surface skins in about half an hour and that sealcoating can follow once it has skinned, if the weather is right. Confirm that on the product you are actually using.
6. Clean Tools Before Material Dries
Water-based filler washes off if you do it immediately. Dried material is what ruins the tool.
When to Choose Hot-Pour vs. Cold-Pour Crack Fillers
They are both preservation tools and they are not interchangeable. Pavement type, appearance, and whether a sealcoat is coming next make the call.
When to Use Hot-Pour Crack Fillers
Heated rubberized blocks for roads, highways, airports, and similar high-demand pavement, applied from an oil-jacketed melter.
When to Use Cold-Pour Crack Fillers
Lots and driveways, where a tight line, appearance, and a later sealcoat matter more than a ten-minute set.
