How to Seal Block Paving
Block paving adds a touch of classic elegance to any driveway or patio. However, to ensure it maintains its beauty and withstands the test of time, proper sealing is crucial.
Sealing block paving will protect your driveway or patio from stubborn stains like oil and grease, as well as biological contaminants such as moss and algae. Fortunately, it is a very simple process that can be achieved with just one easy-to-use product, and applied with a brush, roller or low pressure spray.
This guide will talk to you through how to seal block paving, and give clear instructions on how to maintain your surfaces to keep them looking pristine for the future.
Why Seal Your Block Paving?
Sealing your block paving has many benefits that will keep your patio or driveway looking nicer for longer:
Protection from the Elements: Creates an invisible barrier that repels water, oil, grease, and other stains, safeguarding your investment from the elements.
Stain Resistance: Prevents unsightly stains from everyday spills, including coffee, wine, and motor oil.
Reduced Maintenance: Makes cleaning easier, minimising the effort required to maintain its pristine appearance.
Enhanced Durability: Protects against the damaging effects of frost, de-icing salts, and UV rays, extending the lifespan of your block paving.
Moss and Algae Prevention: Reduces the growth of moss, algae, and other unwanted organisms.
Sealing your block paving does more than preserve the aesthetics of your outdoor space, it protects your investment against harmful contaminants and weathering that can otherwise damage the surface of your driveway or patio.

Application Guide
Prepare the Surface
Clean the Surface: Thoroughly clean the block paving to remove dirt, grime, moss, and algae. Use a suitable cleaner like GK Pro, GK Fungicidal Solution, or GK Greener Kleener.
Check the Weather: Ensure the surface is dry and the weather is suitable for application (between 10°C and 30°C). Avoid applying during rain, frost, or when the surface is damp.
Application Steps
Test: Conduct a small test on an inconspicuous area to ensure the desired results and to calculate consumption.
Apply: Shake the container well before use. Apply a generous, even coat using a brush, long-pile roller, or low-pressure spray. Ensure the surface is saturated.
Mop Up Excess: Remove any excess product with a clean microfibre cloth to prevent a patchy finish.
Multiple Coats (if needed): For highly porous surfaces, apply additional coats (up to 3) while the previous coat is still wet.
Maintenance
Regular Cleaning: Regularly clean the surface using suitable cleaning products like GK Pro, GK Greener Kleener, or GK Concentrated Fungicidal Wash.
Immediate Stain Removal: Remove spills and stains promptly to prevent them from setting. Clean away oil stains with Oil Out.
Important Notes
Do not apply to non-porous surfaces.
Do not apply to painted surfaces or those previously treated with silicone sealants.
Refer to the Safety Data Sheet (SDS) for complete safety instructions.
