Professional Skim Coating
Spalling, pitting, and deteriorating concrete and block surfaces look terrible and continue to worsen. Our cement skim coating services restore and protect residential and commercial surfaces across McHenry and Lake County.
Spalling and pitted surfaces restored with professional cement skim coating
What is Skim Coating and When Do You Need It?
Skim coating is the application of a thin layer of cement-based material over existing concrete, block, or masonry surfaces to create a smooth, uniform, and protected finish. It's the most cost-effective way to restore surfaces that have become rough, pitted, spalled, or aesthetically deteriorated without full replacement.
For both residential homes and commercial buildings, skim coating restores curb appeal, seals out moisture, and extends the lifespan of existing structures. It's commonly used on foundation walls, block walls, concrete columns, retaining walls, and building facades throughout McHenry and Lake County.
Signs Your Surfaces Need Skim Coating:
- Spalling or flaking concrete surfaces exposing aggregate underneath
- Pitting and rough texture on block walls or foundation surfaces
- Visible deterioration from freeze-thaw cycles or salt damage
- Unsightly patched areas that don't match the surrounding surface
- Block walls with deteriorating mortar joints and crumbling face shells
Our Repair Process
Proper surface preparation is the key to a long-lasting skim coat. We follow a meticulous process on every residential and commercial project.
1. Surface Preparation
All loose material, paint, efflorescence, and deteriorated concrete is removed by mechanical grinding, pressure washing, or chemical cleaning. The surface must be clean, sound, and properly profiled for bonding.
2. Application & Leveling
A bonding agent is applied, followed by one or more layers of polymer-modified cement skim coat. Each layer is expertly troweled to create a smooth, uniform surface that fills all voids and imperfections.
3. Curing & Sealing
The skim coat is properly cured to develop full strength and prevent shrinkage cracking. A penetrating sealer is applied to protect the new surface from moisture, salt damage, and UV degradation.

Materials & Techniques We Use
Every skim coating project uses professional-grade materials engineered for durability and long-term performance in Illinois weather.
Polymer-Modified Cement
Fortified cement mix with polymer additives for superior adhesion, flexibility, and crack resistance compared to standard Portland cement mixes.
Acrylic Bonding Agent
Applied to prepared surfaces before skim coating to ensure a permanent mechanical and chemical bond between the existing substrate and new coating.
Fiber-Reinforced Overlay
Skim coat material reinforced with synthetic fibers to resist shrinkage cracking and provide additional tensile strength in thin applications.
Penetrating Concrete Sealer
Silane/siloxane-based sealer that penetrates the skim coat surface to repel water and resist salt damage without changing the appearance.
Elastomeric Waterproof Coating
Flexible, breathable coating applied over skim coats on below-grade walls to prevent moisture infiltration while allowing vapor transmission.
Color-Matched Finish Coat
Pigmented finish layer that can be tinted to match existing surfaces or provide a uniform color across the entire repaired area.
Common Surface Issues We Fix
Surface deterioration is one of the most common problems on concrete and masonry buildings across McHenry and Lake County. Here's what we see most often.
Concrete Spalling & Flaking
Freeze-thaw cycles and salt exposure cause the surface layer of concrete to pop off in flakes and chips, exposing the aggregate and accelerating further damage.
Block Wall Deterioration
CMU (concrete masonry unit) block walls develop rough, pitted surfaces as the face shells erode from weather exposure, creating an unsightly and weakened surface.
Foundation Wall Surface Damage
Exposed foundation walls above grade suffer from spalling, efflorescence, and surface erosion that allows water penetration into the basement or crawl space.
Pitted & Rough Concrete Surfaces
Poor original finishing, deicing salt damage, or age-related wear creates rough, pitted surfaces on walls, columns, and other vertical concrete elements.
Failed Previous Coatings & Patches
Improperly applied paint, stucco, or previous patches that are peeling, cracking, or delaminating from the underlying surface need complete removal and re-coating.
Commercial Building Facade Restoration
Commercial buildings with deteriorating concrete or block facades benefit from skim coating to restore a professional appearance and protect the structure.
