For caulking around a kitchen sink, start with the joint and the surfaces on each side. GE Advanced Silicone 2 Kitchen & Bath is our first option for a compatible, unpainted seal; DAP Silicone Max Kitchen & Bath suits a small job that calls for a squeeze tube; Red Devil 0405 is the paintable choice for compatible kitchen joints.
These products seal joints. They do not replace the clips, frame or other support specified for a sink. For example, Kohler’s installation guide uses sealant together with mounting clips or an undermount support frame. Follow the instructions for your exact sink and countertop before choosing a formula.

| Red Devil Kitchen & Bath Siliconized Adhesive Caulk, 0405, white 5.5 fl oz squeeze tube | Paintability and water cleanup on compatible joints | Protect from water for 24 hours; white formula lists 24-hour full cure, longer in cool or humid conditions |
1. GE Advanced Silicone 2: first choice for an unpainted joint
The exact pick is US item 2812565, white, 10.1 fl oz. This is a neutral-cure 100% silicone, which is useful when the joint should remain flexible and does not need paint. GE lists kitchen sinks and countertops among its applications.
The current technical sheet includes metals, many plastics, granite and natural stone among potential substrates, with important compatibility exclusions. Test adhesion and staining on the exact surface, and obtain approval for sensitive stone, coatings or plastics. “Most plastics” does not mean every polymer.
- Pros: neutral cure; a full-size cartridge for a longer seam; documented kitchen and countertop applications.
- Cons: not paintable; requires a caulking gun; not for structural repairs, continuous underwater exposure or direct or indirect food contact.
Timing: GE’s 30-minute water-exposure claim requires a bead no larger than 3/16 inch, at least 65°F and at least 50% relative humidity. Otherwise, allow eight hours before water exposure. Do not touch or clean the bead for 24 hours or until cured. Typical cure is 24 hours at 73°F and 50% relative humidity, but depth, surfaces and conditions change it.
Buying route: use GE’s product page and retailer options, selecting white 10.1 fl oz item 2812565. Check the size and quantity before ordering.
2. DAP Silicone Max: a small squeeze-tube option
Choose DAP 08795, gloss white, 2.8 fl oz when you need a small amount and prefer a squeeze tube. It is 100% silicone, not paintable acrylic caulk. DAP lists sinks, countertops and backsplashes among its uses.
Its acid-curing formula has a vinegar odor and a different compatibility profile from GE’s neutral-cure pick. The manufacturer’s technical guidance excludes corrosion-sensitive metals such as copper, brass, zinc, iron and galvanized metal. It also identifies adhesion limits with plastics including polyethylene, polypropylene, PTFE, polycarbonate and methacrylate. Do not extend its cultured-marble listing into blanket approval for natural stone.
- Pros: small, gun-free package; flexible silicone seal; specific kitchen applications.
- Cons: nonpaintable; acid-cure metal and plastic restrictions; unsuitable for continuously submerged joints or fully confined spaces where it cannot cure.
Timing: DAP lists water resistance after 30 minutes and full cure after 24 hours at 73°F and 50% relative humidity. Lower humidity slows cure. Early water resistance does not mean the material has finished curing.
Buying route: use DAP’s size selector and Where to Buy options for white 2.8 fl oz model 08795, UPC 070798087958. Do not substitute the larger cartridge or a different DAP kitchen-and-bath formula without checking its instructions.
3. Red Devil 0405: the paintable option
Red Devil 0405, white, 5.5 fl oz is siliconized acrylic caulk, rather than 100% silicone. Consider it for an approved backsplash, trim or other kitchen joint where painting matters. The maker also lists sinks, but your sink’s installation instructions must allow this type of sealant.
Red Devil’s currently linked technical sheet lists wood, tile, marble, glass, plastic, vinyl, metal and fiberglass. These broad categories still require checking the actual finish and material. Do not substitute it where the sink or countertop maker specifically calls for 100% silicone.
- Pros: paintable; uncured material cleans up with water; squeeze-tube packaging suits a small joint.
- Cons: needs at least the specified 24-hour water-protection period; not for below-waterline work or aquariums; paintability does not make it suitable for every sink installation.
Timing: the white formula lists 24-hour full cure and protection from water for 24 hours. Cooler temperatures and higher humidity extend curing. Follow the package and paint instructions before painting; the clear formula has a different cure schedule.
Buying choice: select one white 5.5 fl oz tube, part 0405. The manufacturer also supplies cases of 12; the linked selection is one tube.

How to choose caulk for your kitchen sink
Identify both surfaces and the joint’s job
For a stainless-steel sink, confirm compatibility with the countertop as well as the metal and any coating. For stone, obtain the countertop supplier’s approval and test for discoloration. For plastic or composite sinks, identify the material instead of treating all plastics alike. Follow the sink maker’s specified joint and mounting method.
An exterior rim seam, a backsplash joint and the sealed interface beneath a sink rim are different applications. These recommendations do not make caulk a substitute for drain gaskets, specified mounting adhesives or mechanical support. If a sink has shifted or its support has failed, repair that problem before resealing.
Choose silicone or paintable acrylic deliberately
GE and DAP are useful candidates where approved 100% silicone is required and the finished bead will remain unpainted. Red Devil 0405 adds paintability for joints that permit siliconized acrylic. The word “siliconized” does not identify the same chemistry as 100% silicone.
Plan preparation and downtime
Remove old sealant and leave the bonding surfaces clean, dry and sound as the selected product requires. Check joint dimensions, backing requirements, ventilation and protective equipment in its instructions. Keep water away for the specified period, extending downtime when conditions slow cure. A skinned surface is not proof of a fully cured joint.
Keep kitchen use separate from food-contact approval
A kitchen-and-bath label does not establish direct food-contact or aquarium suitability. GE specifically excludes direct and indirect food contact; Red Devil excludes aquariums. DAP’s technical sheet discusses incidental food contact only after curing and washing, which is not a general approval for a food-contact repair or a fish tank.
Which should you buy?
Start with GE Advanced Silicone 2 2812565 for a compatible unpainted sink joint. Pick DAP Silicone Max 08795 for a smaller job when its acid-cure compatibility limits are acceptable. Choose Red Devil 0405 when paintability matters and the joint permits siliconized acrylic. The sink and countertop instructions take priority over this shortlist.
Frequently asked questions
What caulk should I use around a stainless-steel kitchen sink?
Choose a sealant approved for both the sink and the countertop. GE Advanced Silicone 2 is a neutral-cure 100% silicone candidate for compatible, unpainted joints. Check coatings, adjacent materials and the sink manufacturer’s instructions before using it.
Can I use the sink 30 minutes after caulking?
Only when the exact product’s water-exposure conditions are met. GE’s 30-minute claim has bead-size, temperature and humidity limits, while DAP gives its timing at 73°F and 50% relative humidity. Red Devil 0405 requires 24 hours of water protection, with longer curing in cool or humid conditions. None of these early water times means every joint is fully cured.
Can these sealants hold an undermount sink in place?
Do not use this shortlist as structural mounting approval. Install the clips, support frame or other mounting system specified for the exact sink and countertop. Sealant at the joint does not replace that support.
Which of these kitchen caulks can be painted?
Red Devil 0405 is paintable when its curing and paint instructions are followed. GE Advanced Silicone 2 and DAP Silicone Max are not paintable. Choose the formula the joint requires before considering the finish.
Is kitchen-and-bath caulk automatically safe for food-contact surfaces or aquariums?
No. Kitchen use does not establish those approvals. GE excludes direct and indirect food contact; Red Devil excludes aquariums. DAP’s stated incidental-contact allowance after curing and washing does not establish suitability for every food-contact repair or aquarium. Use a product expressly approved for the intended application.
