Quick Take
If you're comparing sealants and adhesives for construction work, the first fork in the road is pack format. The ASI-55 listings are boxes of new sausage-style tubes, and you can choose the shade that fits your job. The Sika Sikaflex Construction Sealant is a compact cartridge. That difference changes both how much material you have on hand and how you'll apply it. A multi-pack makes sense when you have multiple seams, joints, or surfaces to cover. A single cartridge is easier to justify when the job is small and contained. Before you compare color or formula, ask yourself whether you need a full box or just one tube.
Price Comparison
The listed prices for these four options start at $13.21 and go up to $98.95. That's a wide range, so the real question is whether the larger upfront cost pays off in coverage.

Product Notes
#### 12 Pack- ASI-55 Industrial & Construction Sealant / Adhesive Sausage- gray 20oz

This gray version of the ASI-55 12-pack is the option to look at when you want a gray finish across a large area. The box contains 12 new 20 oz tubes, adding up to 240 oz total, so you can move from one seam to the next without buying another pack. The product is described as a hybrid polyether that can be applied to wet surfaces and in below-freezing temperatures, which helps on difficult jobs. That versatility comes with a specific trade-off: the listed price is $98.95 for the whole box, so you should have a project big enough to use that much material. If you regularly run long sealing jobs, the bulk format is the point; if you only need a small amount, it's a lot of leftover.
#### 12 Pack- ASI-55 Industrial & Construction Sealant / Adhesive Sausage- White 20oz

If white is your color, this ASI-55 12-pack gives you the same sausage-tube format as the gray version. You get 12 new 20 oz tubes and 240 oz total at the same listed price of $98.95. The description includes the same wet-surface and below-freezing application benefits, so it can handle demanding conditions. The limitation is the quantity: it's a full box, so a small repair would leave you with a lot of unused tubes. Still, if you have several areas to seal with white sealant, having one box on hand keeps the job moving and maintains a consistent white finish across the work.
#### 12 Pack- ASI-55 Industrial & Construction Sealant / Adhesive Sausage- black 20oz

The black ASI-55 12-pack rounds out the color choices and costs the same as the other ASI-55 boxes: $98.95. It also has 12 new 20 oz tubes for 240 oz total. What makes it different is the black finish, which can be useful when you want the sealant to blend with dark materials or darker work surfaces. The practical limitation is the bulk format: the box is built for large workloads, not a quick one-off fix. If the job is big enough to justify the purchase, the black option gives you a consistent finish across multiple tubes and keeps you from stopping mid-job.
#### SIKA Sikaflex Construction Sealant - White, All-Purpose Polyurethane for Join

The Sikaflex Construction Sealant is the single-cartridge alternative. The listed price is $13.21 for one 10.1 fl oz white cartridge. It is described as a urethane-based formula that won't stain surfaces and is quick and simple to use with most electric, pneumatic, or hand-powered application guns. It also says the formula meets federal specifications and ASTM standards and helps reduce radon levels. The obvious limitation is that you're buying one cartridge, so for large jobs you'd need to purchase multiple cartridges and reload more often. For small joints, though, the one-cartridge format and smaller footprint make it a practical place to start.
Final Recommendation
Choose the ASI-55 12-pack when you have a lot of surface area to cover and you're comfortable with the full-box format. The available shade options let you match the finish while staying with the same formula family. Choose Sikaflex when the job is small and a shorter supply is enough.
