Sika lists driveways, garages, sidewalks, balconies, pavements, and similar slabs. Loctite lists driveways, garage floors, sidewalks, and concrete floors and decks. It pours into the joint and levels itself, so you do not tool it like vertical caulk.\u003c\/p\u003e\n\u003ch3\u003eSelf-leveling or non-sag concrete sealant?\u003c\/h3\u003e\n\u003cp\u003eUse self-leveling on flat horizontal joints. Use non-sag (gun-grade) on vertical or sloped surfaces. Henkel pairs PL S20 (self-leveling) with PL S10 (non-sag) for that split. Sika pairs Sikaflex Self-Leveling with Sikaflex Construction Sealant for vertical and multi-material joints.\u003c\/p\u003e\n\u003ch3\u003eHow long before I can paint or get rain on it?\u003c\/h3\u003e\n\u003cp\u003eIt depends on the product. DAP AMP rates 1 hour paint and rain ready on a thin bead. Sikaflex Self-Leveling calls for about 1 week before painting or total water immersion. Loctite PL S20 is paintable after full cure, about 7 days per the Henkel sheet.\u003c\/p\u003e\n\u003ch3\u003eDo I need a backer rod?\u003c\/h3\u003e\n\u003cp\u003eFor Loctite PL S20, Henkel calls for a backer rod in joints deeper than 3\/8 in, with sealant depth about half the joint width (min 1\/4 in, max 1\/2 in). Deep joints without a backer rod can bubble. Follow each maker sheet for joint design.\u003c\/p\u003e\n\u003ch3\u003eCan I use it on wet concrete?\u003c\/h3\u003e\n\u003cp\u003eDAP AMP is rated for wet and damp surface application. Sika says Self-Leveling Sealant can go on green or new concrete 24 hours after the concrete has cured, and on wet concrete once the water source has been stopped for 1 hour and there is no standing water. Loctite warns that applying PL S20 too deep or on a substrate that is not absolutely dry can cause bubbling.\u003c\/p\u003e\n\u003ch3\u003eIs the 29 oz Sikaflex Self-Leveling listed?\u003c\/h3\u003e\n\u003cp\u003eThe 10 oz gray cartridge is ACTIVE. The 29 oz size is still draft in the catalog, so the live pick right now is the 10 oz. Sika coverage tables rate about 12.1 linear ft of a 1\/2 x 1\/4 in joint per 10.1 oz cartridge and about 34.9 ft per 29 oz cartridge.\u003c\/p\u003e\n\u003ch3\u003eWill it handle driveway traffic?\u003c\/h3\u003e\n\u003cp\u003eAfter full cure, yes for the polyurethane lines. Loctite describes PL S20 as abrasion and tear resistant for pedestrian and vehicle traffic. Sika lists pavements, driveways, and garages. DAP AMP withstands foot and vehicle traffic after full cure per its TDS. Wait for full cure before heavy traffic.\u003c\/p\u003e\n\u003c\/div\u003e\n","products":[{"product_id":"sika-self-leveling-sealant-gray-10-oz-398-982","title":"Sika Self-Leveling Sealant Gray 10 oz","description":"\u003ch2\u003eSika Self-Leveling Sealant Gray 10 oz\u003c\/h2\u003e\n\u003cp\u003eConquer your weekend concrete project with Sikaflex Self-Leveling Sealant.\u003c\/p\u003e\n\u003cp\u003ePermanently elastic, self-leveling sealant requires no tooling.
