DAMAGED CONCRETE? NOT A PROBLEM! PROFESSIONAL CONCRETE RESTORATION THAT ELEVATES SURFACES INTO ARCHITECTURAL ART.👊👊👊

Our client engaged us for a concrete staining at a School Project in Sengkang (Singapore).

This project involves extensive off-form concrete walls and cylindrical columns. The existing surfaces exhibited multiple challenges:

• Uneven surface

• Uneven joint lines

• Grinding marks

• Visible repair patches

  
  

These flaws collectively diminished the architectural appearance of the structure. ⬇️

Limitations of Conventional Methods

Traditional staining techniques would not have resolved the underlying surface variations, making it nearly impossible to achieve a uniform, natural-looking concrete finish.

Our Solution: 🌟RENUCRETE™🌟, OUR IN-HOUSE CONCRETE MARBLING SYSTEM.

To overcome these challenges, we employed our “Marbling Method ”, a proprietary application system designed to:

📍 Blend uneven tones across large surfaces

📍  Minimize the visibility of repair patches and grinding lines

📍 Create a natural, concrete-like appearance

📍 Provide deep penetration of stain for long-term performance

This method enables controlled layering of silicate-based stains, producing a consistent and durable finish that cannot be achieved with conventional spraying or rolling.

📌 Before application, several essential preparation steps must be completed.

✅ Surface Preparation

1️⃣ Inspection & Repair – Check for cracks, voids, or imperfections and repair them if needed.

2️⃣ Surface Conditioning – Light sanding, or washing (depending on finish) to create the right texture for staining.

3️⃣ Surface Cleaning – Remove dust, laitance, and loose particles to ensure a smooth base.

       Guard Cleaner Surface Preparation

4️⃣ Surface Staining – Apply silicate stain, to ensure a uniform and homogeneous concrete surface. ImperGuard Color Silicate Stain

Only after these steps is the concrete ready for marbling — the stage where true artistry begins 🎨 🎨 🎨 - the shades of grey, dilution ratios, number of coats, application techniques are carefully curated by RENUGLASS technical team on a project basis in order to bridge the gap between site condition and architect's vision. 👇

🔔 Key Takeaway

This project illustrates the importance of selecting the right staining methodology. By moving beyond conventional application methods and leveraging our innovative technique, we were able to restore the architectural integrity of the structure and deliver a long-lasting, natural finish.

✨DIRTY FAIR FACED CONCRETE FACADE? OR STAIN BONDING FAILURE? LET'S HEAR FROM THE EXPERTS✨

Our client at Namly Drive approached us with concerns about the appearance of their fair-faced concrete facade. From a distance, the surface looked patchy, dirty, and uneven, which affected the overall aesthetic of the property. The client initially requested a standard cleaning service. ⬇️

🔎 During our close-up inspection, we discovered that the issue was not dirt buildup but a bonding failure of the previous concrete stain, which had been applied approximately six years earlier. The surface showed clear signs of detachment and inconsistent penetration. ⬇️

💡 The dark spots visible from a distance were exposed concrete where the previous light-grey stain had peeled off. We identified that the failure was most likely due to insufficient surface preparation during the earlier application. Without proper cleaning and pore opening, the stain could not fully impregnate and silicify within the concrete matrix, leading to premature breakdown and patchy appearance.

👊 Our Solution

Instead of a superficial cleaning that would not have resolved the issue, we proposed a comprehensive renovation service:

📍 Thorough Cleaning & Surface Preparation

• Remove remnants of the old stain.

• Concrete cleaning with our Guard Cleaner Surface Preparation to ensure proper bonding.

📍 Re-Staining the Facade

• Apply our concrete stain - ImperGuard Color Silicate Stain designed for deep penetration and long-lasting color stability.

• The color and opacity was chosen in collaboration with the home owner.

📍 Protective Treatment

• Apply our water & oil repellent impregnation - ProtectGuard CE for a long lasting protection against weathering.

💫 Outcome

The renovated facade now showcases a uniform, natural, and elegant finish. Beyond aesthetics, the concrete surface is protected for the years to come. ⬇️

🔔 Key Takeaway

This project highlights the importance of accurate problem diagnosis. While the surface initially appeared “dirty,” the true issue was deeper. By combining our expertise in concrete assessment, surface preparation, staining and protective coating, we delivered a tailored made, lasting solution. ⬇️

The art of transforming concrete expectations into reality... despite below average off form concrete quality

RENUGLASS was appointed to supply & apply our ImperGuard Color Silicate Stain on the precast walls of the internal lift lobby at a new commercial building in Singapore. 

The precast panels had to be partially hacked and repaired with plaster during construction. It was clear that, given the panels condition, applying a concrete stain with the specified dilution of 1:3 would not give a satisfactory result. The result below was understandingly rejected by client as the plaster repair still stand out due to the low opacity:

Result after 2 coats of ImperGuard Silicate Stain dilution 1:3

RENUGLASS proposed an alternative solution that would hide the panels imperfections and repairs while retaining the concrete look design intent. 

How we did it: 

• Sand down the panels to remove extra plaster and achieve a flat surface

• Apply 3 coats of ImperGuard Color Silicate Stain light grey at maximum opacity (1:1) to achieve homogeneity across the panels

• Lightly sand the panels to maximise adhesion

• Apply 1 coat of ImperGuard Color Silicate Stain dark grey using sponging method to create an earthy concrete look

Here is the result in 3 steps:

RENUGLASS objective is not just to deliver on a predefined scope of work (i.e: apply 2 coats of silicate stain on off form concrete) but to find the way to achieve the architect vision regardless of the external parameters like the concrete quality. We are purpose driven and always strive to deliver quality work with innovative solutions.
