Clean and Seal
Protect. Refresh. Extend the Life of Your Concrete.
Whether it’s brand-new or years old, concrete deserves long-lasting protection. At CONDEC, our Clean and Seal service brings tired surfaces back to life — removing dirt, stains and mildew before applying a premium sealant that protects against wear, weather and water damage.

From exposed aggregate and coloured concrete to stamped and honed finishes — we clean and seal all types of decorative concrete with care.
Why Seal Your Concrete?
Concrete is tough, but it’s also porous. Without sealing, moisture, oils, and dirt can soak in, causing discolouration, cracking, or moss build-up.
Sealing helps:
- Extend the life of your concrete
- Prevent stains, mould and weather damage
- Enhance colour and finish
- Make surfaces easier to clean
- Improve slip resistance
The Clean & Seal Process
Our 3-step process is designed for longevity and impact:
1. Assessment & Prep
We inspect the surface and select the right cleaning method.
2. High-Pressure Cleaning
Removes built-up grime, oil, mould and debris.
3. Sealant Application
We apply a premium-grade sealer for long-lasting protection.
Clean & Seal FAQs
How often should concrete be sealed?
Every 2–3 years is ideal for most driveways and outdoor areas. High-traffic zones may need more frequent resealing.
Can you seal old concrete?
Yes — as long as it’s structurally sound. We’ll clean and prep it thoroughly before sealing.
Will sealing change the look?
Acrylic sealers can deepen colour and add a light sheen. Penetrating sealers keep the surface natural.
Is sealing slippery?
Not with the right additives. We can include non-slip grit to maintain traction on any surface.
How long does it take to dry?
Surfaces are usually dry in 1–2 hours, and fully cured in 24–48 hours (weather dependent).
Can I seal it myself?
DIY sealers exist, but our commercial-grade products and pro application deliver far better, longer-lasting results.
