FAQ: Overlay vs. Demolition
Traditional demolition can be messy, costly, and time-consuming — but resurfacing with modern overlay systems offers a faster, cleaner, and more sustainable alternative.
At Alt. Surfaces, we specialise in a high-performance microcement overlay called X-Bond, designed to that transform existing floors, walls, and joinery without the need for demolition. Below, we’ve answered the most common questions about how overlays compare to full replacement so you can choose the best approach for your renovation.
Q. What’s the difference between overlay and demolition?
Demolition involves completely removing existing materials before reinstalling new substrates and finishes — for example breaking up concrete or ripping out tiles. It’s time-consuming, noisy, messy, and often costly.
An overlay, by contrast, is a thin resurfacing system applied directly over existing surfaces. Using advanced materials such as microcement, overlays create a brand-new finish without the need to remove what’s underneath. This makes overlays ideal for renovations and remodels where speed, precision, and minimal disruption are key.
Q. Is an overlay as durable as replacing the surface entirely?
Yes — when properly installed, high-quality overlays like X-Bond Microcement are engineered for exceptional adhesion and strength. The key to long-term performance lies in correct surface preparation and professional installation.
An overlay bonds to the substrate, forming a flexible, durable finish capable of withstanding heavy use. In most residential and commercial settings, it performs just as well (if not better) than new concrete or tile installations.

Q. When is demolition the better option?
Only once the underlying structure is sound can a microcement or overlay system perform as intended — providing a long-lasting, seamless finish that won’t fail over time.
Therefore, demolition may be necessary if:
The existing substrate is severely unstable, crumbling, or excessively cracked beyond repair.
There’s significant moisture damage beneath the surface.
The floor or wall structure needs re-levelling or rebuilding.
In most other cases, a resurfacing system can be applied directly over the existing surface — saving time, cost, and waste.
Q. What are the benefits of choosing overlay instead of demolition?
Are you deciding whether to demolish your old floor or walls, or just resurface over the top? Choosing an overlay means achieving the look and performance of a brand-new material without the demolition headache.
| Overlay / Resurfacing | Demolition & Replacement |
|---|---|
| Minimal dust, machinery and noise | Noisy, messy, labour-intensive often with heavier machinery |
| Applied over existing surfaces | Requires full removal of old material |
| Fast installation | Extended downtime |
| Eco-friendly — reduces landfill waste | High material waste and disposal costs |
| Thin profile (2–3 mm) | Adds new thickness, may require re-levelling |
| Seamless, modern finish | Traditional segmented finishes |
Q. Can overlays go over tiles or concrete?
Absolutely. Systems like X-Bond Microcement are designed to adhere to almost any stable surface — including concrete, tiles, plasterboard, screed, and even MDF joinery.
Q. How long does an overlay last?
With proper installation and maintenance, a microcement overlay can last decades. Regular cleaning and some light upkeep will help maintain its appearance and performance, much like a traditional concrete floor.

Q. Is overlay cheaper than demolition?
In most cases, yes. While exact costs depend on surface area and project scope, overlays typically:
Reduce labour hours (no demolition or disposal)
Eliminate waste removal costs
Shorten project timelines
This makes overlays a cost-efficient renovation solution to delivering a high-end architectural finish with less disruption and downtime.

Q. Who should install an overlay system?
Overlay performance depends on the skill of the installer; it’s therefore not recommended as a DIY project. At Alt. Surfaces, our team of X-Bond Microcement applicators are trained in correct substrate preparation and application techniques.

Q. Can your overlays be used outdoors?
Yes, X-Bond is suitable for outdoor floors, facades, and pool surrounds when the correct system and sealer are used. It’s UV-stable, water-resistant, and ideal for extending indoor finishes seamlessly to outdoor areas.
Overlay systems like X-Bond Microcement redefine what’s possible in modern renovations. They combine strength with adaptability and the beauty of a handcrafted finish — without the waste, mess, or downtime of traditional demolition.
If your surface is sound, you don’t need to tear it up. You just need to overlay it.
