Pattern imprinted concrete (PIC) has become a go-to choice for UK homeowners and contractors seeking the look of stone, brick, or slate with the durability of concrete. However, like any decorative surface, imprinted concrete requires protection to maintain its vibrant colour and resilient surface. This is where a quality imprinted concrete sealer comes in - a product that’s often misunderstood, but essential for long-term results.
Why Use an Imprinted Concrete Sealer?
Imprinted concrete is porous and exposed to the elements, vehicle traffic, and daily wear. Without a sealer, it can quickly lose its colour, become stained, or even start to crack. Here’s what a good concrete imprint sealer does:
-
Protects Against Stains: Repels oil, petrol, tyre marks, and food spills, making cleaning much easier.
-
Prevents Colour Fading: Locks in colour hardeners and decorative tints, keeping your driveway or patio looking fresh and vibrant.
-
Enhances Appearance: Adds a gloss or satin finish that brings out pattern depth and makes decorative surfaces pop.
-
Guards Against Weather Damage: Blocks water penetration, reducing freeze-thaw damage and surface wear.
-
Improves Durability: Reduces surface dusting, cracking, and general wear, prolonging the life of your investment.
Imprinted Concrete Sealer: Myths and Misconceptions
“All concrete sealers are the same.”
Not true. Imprinted concrete sealers are specially formulated (often acrylic-based) to penetrate textured surfaces and lock in decorative finishes. General concrete sealers may not provide the same colour enhancement or durability.
“Sealing makes concrete slippery.”
Modern sealers often include anti-slip options, like silica grit, so you can enjoy a glossy finish without sacrificing safety, especially on slopes or pool surrounds.
“You only need to seal once.”
Even the best concrete sealer needs reapplication every few years, especially in high-traffic or exposed areas.

-
Deep Penetration: Look for a resin blend that soaks into the surface, binding loose particles and enhancing pattern depth.
-

-
Custom Finish: Choose from clear or tinted gloss, or add anti-slip silica for a textured satin finish.
-
UV and Stain Resistance: Essential for driveways and patios exposed to sun, oil, and vehicle traffic.
-
Easy Application: Ready-to-use formulas that can be rolled or sprayed make life easier for both DIYers and professionals.
Step-by-Step: How to Apply Imprinted Concrete Sealer
-
Prep the Surface:
Pressure-wash to remove dirt, algae, and residues. Allow the surface to dry fully (moisture ≤ 4%). Remove any old, flaking sealers. -
Prime if Needed:
On bare or highly porous concrete, apply a primer to ensure even absorption and better adhesion. -
Mix and Add Anti-Slip:
Stir the sealer for two minutes. For anti-slip, gradually add the silica pack and stir until evenly suspended. -
First Coat:
Apply thinly with a solvent-resistant roller or low-pressure sprayer. Avoid puddling or over-application. -
Second Coat:
After 4–6 hours, apply a cross-direction second coat. For high-traffic areas, a third clear coat can boost depth and durability. -
Curing:
Keep the surface dry for at least 6 hours. Wait 48 hours before allowing vehicle traffic, and 7 days for full chemical cure.
Pro Tips:
-
Avoid sealing in extreme temperatures or when rain is forecast.
-
Ensure good ventilation during application and drying.
-
Always wear gloves and a vapour mask for safety.
Frequently Asked Questions About Concrete Sealers
Does concrete paint need a sealer?
If you want to prolong the life and colour of painted concrete, a clear sealer is highly recommended. It protects against wear, stains, and fading.
Can I paint over concrete sealer?
Generally, paint won’t adhere well to sealed surfaces unless the sealer is specifically designed to be painted over. Always check manufacturer guidance.
Can I apply three coats of concrete sealer?
Yes, especially on very porous or high-wear areas. Just ensure each coat is thin and the previous coat is fully dry before reapplying.
Can concrete sealer be used on wood?
No, Concrete sealers are formulated for mineral surfaces and may not bond or perform well on wood.
Can I paint over Bostik concrete sealer?
Check the product label. Most solvent-based sealers are not designed to be painted over without abrasion or special primers.
