At Dortech Direct, we get asked on a regular basis: "Do I need to use a sealer or a sealant for this work?" To help you out, let's break it down in simple language.
What Is a Sealer?
A sealer is a liquid coating that penetrates or rests on the surface to protect it from water, stains, dust, or chemicals. You can think of it as a protective shield that avoids materials like stone, wood, or concrete from being harmed by moisture and wear.
For example, if you’ve recently laid a new patio, driveway, or tile surface, applying a sealer ensures it stays protected for years to come. It helps prevent stains, cracking, and fading caused by everyday use and weather exposure.
How a Sealer Works
Sealants are put onto surfaces and never into cracks. The major purpose is to decrease porosity and render the surface more resistant. Sealers penetrate within the material in order to develop an unnoticeable barrier in certain situations, while others leave a glossy or matte finish on the surface.
A popular example is the Everbuild Sealer, available on Dortech Direct, that provides long-lasting protection for masonry, stone, and paving surfaces. It's designed to resist water entry and retard surface wear and tear — ideal for use outdoors.
What Is a Sealant?
A sealant, on the other hand, is a flexible material which is used to seal gaps, joints, and cracks between two materials. It does not permit air, water, or dust to pass through the joint but contains some provision for limited movement of the materials without cracking.
If you’ve ever used silicone around your bathroom sink or window frames, that’s a sealant in action. Its job is to seal spaces and ensure the area remains watertight and airtight.
One of the best-selling types is the Everbuild Silicone Sealant, which you can buy in varying types — sanitary, neutral cure, or general-purpose — from Dortech Direct. They are trusted by the professionals for their strength, flexibility, and durability.
When to Use a Sealer
You'll be needing a sealer when you want to stop a surface from taking in or weathering. These are some common instances:
Concrete driveways and patios – Prevent water penetration and cracking.
Wooden furniture or decks – Insulate against UV rays, moisture, and stains.
Natural stone tiles – Lessen staining and clean more easily.
If you're working with materials such as brick, stone, or concrete, the Everbuild Sealer is ideal. It's simple to apply, dries colorless, and improves the durability of surfaces without affecting their look.
When to Use a Sealant
Apply a sealant if you need to seal gaps or create a watertight joint. Some of the common uses are:
Around sinks, bathtubs, or showers – To stop water leakage.
Around windows and doors – To prevent air drafts and water entry.
Between expansion joints in concrete – To provide flexibility without allowing water entry.
The Everbuild Sealant range by Dortech Direct has something to suit any task — from the Everbuild Silicone used around bathrooms and kitchens to hybrid sealants for construction. They adhere well to most substrates and remain flexible even under varying temperatures.

How to Apply Sealers and Sealants Properly
Sealants and sealers are easy to use, but a couple of easy steps can result in the best result.
For Sealers:
Clean the surface thoroughly — remove dust, dirt, or oil.
Let it dry completely before application.
Apply evenly with brush, roller, or sprayer.
Let it cure as specified by the product instructions (typically a few hours).
Reapply as necessary, depending on the porosity of the surface.
For Sealants:
Clean the surface of the gap or joint to form adhesion.
Cut the nozzle at an angle for easy control.
Seal smoothly into the joint using a sealant gun.
Smooth the bead with a finish tool or wet finger.
Allow 24 hours for the surface to cure before exposing it to moisture.
These instructions apply to most Everbuild sealant and Everbuild silicone.
Always refer to packaging instructions for the best result.
These processes can be used for the majority of Everbuild sealant and Everbuild silicone products. Always follow the instructions on the product packaging for optimal results.
