Rent the melter,
seal like a crew.

The Crafco Super Shot 125: a 125-gallon, oil-jacketed melter/applicator on a tow-behind trailer. It heats rubberized crackfiller blocks to ~380°F in the heat-transfer-oil vat (no scorching, unlike direct-fire kettles) and feeds a hose-and-wand for controlled placement. Bring a vehicle with a hitch; we’ll handle the hookup walkthrough at pickup. It's the same class of machine our crews run — which is the point. Cold pour from a jug shrinks and fails by spring; hot-applied rubber bonds to crack walls and flexes for years.

The sealant only bonds to clean, dry crack walls. Blow every crack out with compressed air (rent a compressor if you don't own one), kill vegetation growing in cracks a few days ahead, and work on a dry day above 45°F. An hour of prep per hundred feet of crack is the honest ratio — skip it and you're gluing rubber to dust.

Light it per the walkthrough we give at pickup, feed blocks as the vat draws down, and keep material in the working range — too cool strings, too hot degrades. Move the wand at a steady walk, slightly overfilling, then strike flush with the included tool or a squeegee. A first-timer does 300–500 feet of crack per hour once the rhythm lands. Traffic can return as soon as the sealant skins — minutes in summer.

Daily and weekly rental rates plus Crafco blocks at our counter — call (559) 442-4105 for current pricing and dates. Rule of thumb: an HOA or yard with 1,500+ feet of cracking usually saves real money DIY-ing with our machine and materials; a homeowner with one driveway is usually better off having our crew do it during a grouped route. We'll tell you which side you're on — even when it's the smaller ticket.
