The Ultimate Guide to Cleaning and Sealing Pattern Imprinted Concrete

Essential Maintenance Tips for Pattern Imprinted Concrete

Pattern imprinted concrete (PIC), also known as stamped or decorative concrete, mimics the appearance of stone, brick, slate, or tile—while offering the strength and durability of poured concrete. To keep it looking fresh and protect it from the elements, proper maintenance is essential. This guide covers everything you need to know about cleaning and sealing PIC to ensure long-term performance and a beautiful finish.

Why Maintenance Matters

Without regular upkeep, pattern imprinted concrete can suffer from:

  • Fading due to UV exposure
  • Stains from oil, leaves, or rust
  • Surface wear and microcracks
  • Algae, moss, and weed growth in joints

By cleaning and sealing your surface regularly, you can:

  • Preserve colour and shine
  • Prevent cracking and surface damage
  • Protect against moisture, stains, and organic growth
  • Extend the lifespan of the concrete by several years

Part 1: Cleaning Pattern Imprinted Concrete

Tools & Materials You’ll Need

  • Broom or leaf blower
  • Stiff brush
  • Power washer (optional but ideal)
  • Mild detergent or degreaser
  • ProClean Moss & Algae Remover
  • Protective gear (gloves, goggles)

Step-by-Step Cleaning Process

  1. Clear the Surface: Remove loose debris, leaves, and dirt using a broom or leaf blower.
  2. Apply Cleaning Solution: Use warm water with a mild detergent or concrete cleaner. For oil, use a degreaser; for moss or algae, apply a moss killer like ProClean.
  3. Scrub Thoroughly: Work the cleaner in with a stiff brush and let it sit for 10–15 minutes.
  4. Rinse with a Pressure Washer: If available, use a pressure washer to rinse the surface, taking care not to erode the concrete.
  5. Allow to Dry Completely: Ensure the surface is 100% dry before sealing. Trapped moisture can lead to peeling or whitening.

Pro Tip: Clean your surface on a dry, mild day. Avoid doing it in direct sunlight to prevent streaks.

Choosing the Right Concrete Sealer

There are two primary types of sealers for pattern imprinted concrete:

  • Acrylic Solvent-Based Sealers: Provide a glossy finish and colour enhancement. Ideal for driveways and high-traffic areas. Browse our concrete sealants.
  • Water-Based Sealers: Low-odour and more eco-friendly. Suitable for residential or low-traffic areas.

Step-by-Step Sealing Process

  1. Check the Weather: Ensure dry weather for at least 24 hours. Best temperature range: 10–25°C.
  2. Prepare the Area: Mask walls and edges. Make sure the surface is dust-free and completely dry.
  3. Mix and Apply the Sealer: Stir thoroughly. Add ProGrip if desired. Apply a thin, even coat using a sprayer or application broom. Let it dry for 2–4 hours.
  4. Apply a Second Coat: For porous or worn areas, a second thin coat improves durability.
  5. Allow to Cure: Wait 24–48 hours before using the surface for walking or driving.

Maintenance Tips

  • Reseal every 2–4 years, depending on usage and exposure
  • Sweep regularly to prevent dirt build-up
  • Clean oil or chemical spills quickly
  • Avoid harsh de-icers in winter—use sand or eco-friendly alternatives

Common Mistakes to Avoid

  • ❌ Sealing a damp surface
  • ❌ Applying the sealer too thickly (causes bubbling and white spots)
  • ❌ Using indoor-only sealers outdoors
  • ❌ Skipping the cleaning or surface preparation

Final Thoughts

Cleaning and sealing your pattern imprinted concrete is one of the best ways to preserve its beauty and structural integrity. With the right techniques and quality products, you can enjoy a surface that not only looks great but lasts for years.
