Common Questions This Guide Answers

  1. What is the difference between an adhesive and a sealant? → Adhesives bond materials together; sealants close gaps and seams against water, air, and dust — though some Selleys products perform both functions simultaneously.
  2. Which Selleys product is best for bathrooms and wet areas? → Selleys Wet Area Silicone — a mould-resistant silicone sealant formulated for bathrooms, kitchens, and laundries.
  3. Can sealant be painted over? → Acrylic sealants are paintable once fully cured; silicone sealants are generally not paintable — choose an acrylic or paintable hybrid sealant for painted finishes.

Adhesives & Sealants

Selleys has been the trusted name in adhesives and sealants for over 80 years, and there's a reason tradespeople and DIYers keep reaching for it. Whether you're securing a loose tile, weatherproofing a bathroom, or working through a full renovation, the right product makes the difference between a job that holds and one you'll be redoing in six months.

Here's what you need to know to pick the right product and apply it properly.

What are adhesives and sealants?

Adhesives and sealants are two distinct product types, though they often work together on the same job.

Adhesives bond materials together — wood, metal, ceramic, plastic, glass, and more. A good adhesive creates a strong, lasting connection that holds under pressure, movement, and everyday wear.

Sealants close gaps, joints, and seams to keep out water, air, dust, and noise. A reliable sealant protects your work from moisture damage, draughts, and deterioration, preserving the quality of your finish for years.

Many Selleys products do both at once, bonding surfaces while sealing against the elements in a single application.

Choosing the right product

Three things determine which product you need: the materials you're working with, the conditions the joint will face, and the finish you want.

Materials

Different surfaces need different formulations. Porous materials like timber and concrete absorb adhesive differently to smooth, non-porous surfaces like glass or metal. Always check that your chosen product is compatible with both surfaces you're joining or sealing.

Conditions

Think about what the finished joint will be exposed to:

  • Moisture and water — bathrooms, kitchens, outdoor areas, and wet zones need a waterproof or water-resistant product
  • Heat and UV — outdoor applications and areas near heat sources need a product that won't break down under temperature extremes
  • Movement and vibration — joints that flex, expand, or contract need a flexible sealant that moves with the structure rather than cracking
  • Load and weight — structural bonding needs an adhesive with the holding strength to match the task

Finish

Visible joints and seams need a sealant that looks as good as it performs. Selleys sealants deliver smooth, clean, professional results.

Selleys adhesive and sealant range

Construction adhesives

Selleys construction adhesives are built for tough jobs — bonding timber frames and flooring, securing heavy panels and cladding, and anything else that needs to stay put.

Selleys Liquid Nails is Australia's leading construction adhesive, trusted by tradespeople and DIYers for its bonding strength across a wide range of building materials. It bonds timber, plasterboard, concrete, brick, foam, and more with a grip that holds firm under pressure.

Silicone sealants

Silicone is the go-to for wet areas, glazing, and anywhere you need long-lasting flexibility combined with waterproof protection. Selleys silicone sealants stay flexible for the life of the joint, resisting mould, mildew, and moisture without cracking or shrinking.

Selleys 401 Roof & Gutter silicone is UV-stable, waterproof, and built to handle Australia's toughest weather conditions in exposed outdoor applications.

Selleys Wet Area Silicone is the professional choice for bathrooms, kitchens, and laundries. Its mould-resistant formulation keeps wet area joints clean and performing at full strength year after year.

Polyurethane sealants

Polyurethane sealants offer strong flexibility and adhesion on porous surfaces like concrete, timber, and masonry. They're the right choice for expansion joints, driveways, paths, and structural sealing where movement is a factor.

Selleys Polyurethane Sealant bonds and seals in a single application, delivering a tough, paintable finish that holds up to heavy traffic and outdoor exposure.

Acrylic sealants

Acrylic sealants are the practical choice for interior gaps, cracks, and joints that will be painted over. They apply cleanly, sand smoothly, and accept paint without lifting or peeling.

Selleys Spakfilla and Selleys No More Gaps are trusted by painters and renovators across Australia for delivering clean, paintable results that make every job look its best.

Epoxy adhesives

When maximum strength is non-negotiable, epoxy is the answer. Two-part epoxy systems chemically bond to create a joint stronger than the materials themselves — ideal for structural repairs, metal bonding, and high-load applications.

Selleys Araldite is the benchmark for epoxy adhesive performance, a heritage brand trusted by engineers, tradespeople, and DIYers for decades. When the job demands a bond that won't fail, Araldite delivers.

Specialty adhesives

Not every job fits a standard category. Selleys specialty adhesives cover the full range of bonding challenges, from contact adhesives for laminates and rubber to super glues for fast, precise repairs.

Selleys Kwik Grip contact adhesive gives you an instant, high-strength bond on laminates, veneers, rubber, leather, and more. Apply to both surfaces, allow to dry, and press together for a grip that holds from the moment contact is made.

Selleys Super Glue delivers fast, precise bonding on a wide range of materials, ideal for repairs where speed and accuracy matter.

How to get professional results

The right product is only part of it. Preparation and application are what separate a result that lasts from one that lets you down.

Surface preparation

Clean, dry surfaces are the foundation of a strong bond or seal. Remove dust, grease, oil, old sealant, and any loose material before you start. On smooth surfaces, light abrasion improves adhesion. On porous surfaces, a primer may be required — check the product instructions.

Application

Apply adhesive or sealant within the recommended temperature range. Most products perform best between 5°C and 35°C. Cold temperatures slow curing; extreme heat can affect adhesion.

For sealants, cut the nozzle at a 45° angle to match the bead size you need. Apply in a single, steady pass and tool the bead immediately for a clean finish. Use masking tape to protect adjacent surfaces and remove it while the sealant is still wet.

For adhesives, pay attention to the open time — the window between application and when the bond is made. Pressing surfaces together too early or too late both affect the final strength of the joint.

Curing

Allow the full cure time before putting the joint under load or exposing it to water. Skin-over time tells you when the surface is touch-dry, but full cure takes longer. Check the product data sheet for specific cure times under your conditions.

Frequently asked questions

How do I remove old sealant before applying a new one?

Score the old sealant with a sharp blade and peel it away. Use a sealant remover to break down any residue, then clean the surface thoroughly before applying fresh sealant. A clean surface is what makes the new bond last.

Can I paint over sealant?

Acrylic sealants are paintable once fully cured. Silicone sealants are generally not paintable — if you need a painted finish, choose an acrylic product or a paintable hybrid sealant. Check the product label to confirm paintability before you start.

How long does silicone sealant last?

A quality silicone sealant applied correctly to a properly prepared surface will last 20 years or more. Mould, cracking, or shrinkage are signs of poor surface preparation, the wrong product choice, or a product past its service life.

What's the difference between a sealant and a filler?

Fillers like Spakfilla are rigid once cured — designed for static cracks and holes that won't move. Sealants stay flexible and are designed for joints and gaps where movement, vibration, or thermal expansion is expected. Put a rigid filler in a moving joint and it will crack.

How do I get a smooth sealant finish?

Apply masking tape to both sides of the joint before you apply sealant. Run the bead in a single, steady pass, then smooth it with a wet finger or a sealant tool. Remove the masking tape immediately, before the sealant skins over, for a clean, sharp edge.
