Walk into any hardware shop and ask for “glue,” and the honest answer is a question back: glue for what? A laminate tabletop, a leaking bathroom joint, a loose chair leg, and a mirror fixed to a wall are four completely different problems, and no single tube solves all four. Pick the wrong one and the bond fails, sometimes in a week, sometimes in a monsoon.
At Khandelwal Trading Co. in Panchkula, this is one of the most common counter conversations we have with both homeowners and trade customers across the Tricity. So this guide lays out how to choose between adhesives and sealants the way an experienced hand would: start with the two materials you are joining, then the conditions the joint will face, and the right product usually picks itself. We will keep it practical, and link out to detailed guides where a particular job deserves its own deep dive.
Adhesive or Sealant? First, Know the Difference
People use the words interchangeably, but they do two different jobs.
- An adhesive bonds. Its job is to hold two surfaces together and take load: a laminate stuck to plywood, a beading fixed to an edge, two pieces of wood joined at a joint.
- A sealant seals. Its job is to close a gap and stay flexible, keeping water, air, and dust out while allowing the surfaces on either side to move slightly, such as the line where a wash basin meets the wall, or the joint around a window frame.
Some products blur the line and do a bit of both, but the rule of thumb holds: if you need holding strength, reach for an adhesive; if you need a watertight, flexible fill, reach for a sealant. Get this first choice right and half the battle is won.
The Two Questions That Decide Every Bond
Before you look at any brand or tube, answer these two questions. They narrow the choice faster than any label.
1. What are you joining?
Porous to porous (wood to wood), porous to non-porous (laminate to plywood, tile to wall), or non-porous to non-porous (glass to aluminium, metal to metal). Porous surfaces soak in water-based adhesives and grip well. Smooth, non-porous surfaces often need a contact adhesive, an epoxy, or a silicone instead, because a water-based glue simply cannot key into them.
2. What will the joint face?
Water and humidity, heat, sunlight, constant flexing, or heavy load all change the answer. A drawer joint indoors and a joint on a bathroom counter live in different worlds. In our climate, monsoon damp and summer heat are the two conditions that catch people out most, so always factor them in before buying.
Adhesives: Which One for Which Job
Most everyday bonding jobs fall into a handful of families. Here is how to think about each, with the Fevicol and Pidilite ranges we stock at KTC.
Wood and laminate work
This is the biggest category for carpenters and homeowners alike. The classic white synthetic resin adhesive, Fevicol SH, is the workhorse for interior woodwork and general lamination onto plywood, MDF, and block board. For areas that see moisture, such as kitchens and bathrooms, Fevicol Marine offers water resistance that ordinary wood glue cannot match. And where a surface gets genuinely hot, like a kitchen counter near a burner or a top that catches direct sun, Fevicol Heatx is built to resist heat up to around 170 degrees Celsius without letting go.
Because this range has so many grades, we have given it a dedicated breakdown. See our full guide on the Fevicol range decoded (SH, Marine, Heatx and 505) to match the exact grade to your job.
Contact bonding (laminate, rubber, leather, foam)
When you are sticking a large sheet of laminate, rubber, or leather and need it to grab the instant the two surfaces meet, you want a contact adhesive rather than a wood glue. Fevibond and the synthetic-rubber contact adhesives are made for exactly this: coat both surfaces, let them go tacky, then press together for an immediate hold. The technique matters as much as the product here, so we have written it up separately in our guide to contact adhesives for laminate, rubber and leather.
Instant fixes and repairs
For small, quick repairs on plastic, rubber, ceramic, and metal, an instant cyanoacrylate (the “super glue” family) or a two-part epoxy putty does the job in minutes. These are for spot repairs and small parts, not for load-bearing furniture joints, where a proper wood adhesive and clamping will always outlast them.
Strong, lasting furniture joints
A furniture joint that lasts is as much about technique as glue: the right adhesive, good surface contact, and proper clamping while it cures. We cover the full method in our guide to strong furniture joints and wood-glue technique, which is worth reading before your next carpentry project.
Nail-free and drill-free fixing
Sometimes you want to fix a skirting, a beading, an ACP panel, or a bathroom fitting without drilling holes or hammering nails, either because the surface is delicate, or because you simply want a cleaner finish. Modern construction adhesives, including the Wondernail range we stock, are engineered to grab hard on such fixings. When drilling makes sense and when adhesive is the smarter call is covered in our guide to nail-free construction adhesives versus drilling.
Sealants: Which One for Which Job
Sealants are where a lot of money gets wasted, because the wrong type in a wet or moving joint fails and has to be redone. There are three families to know, and the Feviseal and Dr. Fixit ranges cover them.
Silicone sealants
Silicone is the go-to for wet areas, glass, and glazing because it stays flexible and repels water well. Within silicone there are two important sub-types. Acetoxy silicone (such as Feviseal Acetoxy) cures fast and grips strongly on glass and glazed tiles, but it gives off a vinegar-like smell as it cures and is not suited to some metals and natural stone. Neutral silicone (such as Feviseal Neutral Pro) is low-odour and far safer on stone, metal, and mirrors, which is why it is preferred for sensitive surfaces. For exposed exterior joints, a weatherproof grade built for UV and water is the right pick.
PU (polyurethane) sealants
Where a joint has to seal and take some structural movement or abrasion, a polyurethane sealant like Dr. Fixit PU Sealant steps up. PU bonds strongly to concrete, masonry, wood, and metal, can be painted over, and handles expansion joints and heavier-duty applications that silicone is not meant for.
Acrylic sealants
Acrylic sealants are the economical choice for interior gap-filling in dry areas, such as filling cracks and gaps before painting, because they can be painted over and smoothed easily. They are not for constant water exposure or joints that flex a lot; use silicone or PU there instead.
Choosing between these three is a common source of confusion and costly mistakes, so we have a full comparison in our guide to silicone vs PU vs acrylic sealants.
Quick Selector: A Cheat Sheet
When you are standing at the counter and want a fast steer, this is the short version.
- Laminate onto plywood or MDF: Fevicol SH for interiors; Fevicol Marine where it stays damp; Fevicol Heatx near heat.
- Rubber, leather, foam, or big laminate sheets: a contact adhesive such as Fevibond.
- Loose furniture joint: a proper wood adhesive plus clamping, not super glue.
- Skirting, beading, ACP, fittings without drilling: a construction adhesive such as Wondernail.
- Small plastic, ceramic, or metal repair: instant glue or epoxy putty.
- Bathroom, sink, glass, and tile joints: silicone (neutral on stone and metal, acetoxy on glass and glazed tile).
- Concrete, masonry, and moving joints: PU sealant.
- Interior gaps and cracks before painting: acrylic sealant.

Common Mistakes to Avoid
- Using an adhesive where you need a sealant. A rigid glue in a joint that moves will crack; use a flexible sealant instead.
- Ignoring moisture. An interior wood glue in a wet area is the single most common reason a bond fails in the Tricity monsoon. Match the product to the damp.
- Skipping surface prep. Dust, grease, and old sealant kill adhesion. Clean and dry the surface first, every time.
- Acetoxy silicone on stone or mirrors. It can stain or corrode. Use a neutral-cure silicone there.
- Not clamping. Most wood adhesives need firm contact while curing. No clamp, no strength.
Frequently Asked Questions
What is the difference between an adhesive and a sealant?
An adhesive bonds two surfaces together and carries load. A sealant fills a gap and stays flexible to keep out water and air while the surfaces move slightly. If you need holding strength, use an adhesive; if you need a watertight, flexible fill, use a sealant.
Which Fevicol should I use for laminate work?
Fevicol SH is the standard choice for interior lamination on plywood and MDF. Choose Fevicol Marine for damp areas like kitchens and bathrooms, and Fevicol Heatx where the surface gets hot. Our detailed Fevicol range guide walks through each grade.
Can I use silicone sealant in a bathroom?
Yes. Silicone is ideal for bathroom and wet-area joints because it stays flexible and repels water. Use a neutral-cure silicone on natural stone, metal, and mirrors, and an acetoxy grade on glass and glazed tiles.
What can I use to fix things without drilling holes?
Construction adhesives such as the Wondernail range can fix skirtings, beadings, ACP panels, and light fittings without drilling. They suit clean, sound surfaces. Our nail-free fixing guide explains when adhesive beats drilling and when it does not.
