Why is Primer so Important for Paving Slabs?
Paving Primer is primarily used on Porcelain Paving tiles by Landscapers, with some using it on natural stone pavers such as Sandstone Paving and Limestone Paving, as well as Cobble Setts and Block Paving.
Our recommendation would always be to use Pro-prime Paving Primer on Porcelain Paving. This is because these paving slabs are man-made and therefore have smoother sides and typically less 'grip' than natural paving.
By priming your Porcelain Paving slabs before you lay them onto your mortar bed, you are giving them a bonding agent that will firmly bond the paving slabs to the mortar bed in a way that will stand the test of time throughout all weather conditions, as well as footfall on your garden patio.
If you don't use a Paving Primer on Porcelain Paving, over time you may experience some movement of your patio slabs, where they can essentially 'un-stick' from the mortar bed, which will cause problems down the line which will be hard to fix.
How to Use Pro-prime Paving Slurry Primer
Whether you're a landscaping professional or an experienced gardener that has decided to lay paving slabs, you'll need to ensure you're using a high quality Paving Primer, especially on Porcelain Paving tiles. Read our step-by-step guide below for some top tips on how to use this Paving Slurry Primer. Please note that this paving primer has a workability time of 1 hour.
Precautions: This product requires careful handling; we recommend wearing protective gloves and clothing. As this product contains cement which is highly alkaline, skin irritation may occur when in contact. If this product gets into your eyes, wash out immediately with clean water and seek medical attention if irritation persists. This should be used in a well-ventilated area and mixed carefully to avoid too must dust rising.
Step 1 - Preparation
Once you have prepared your mortar base - tips on Laying Paving Slabs can be found here - you should be ready to start priming your paving slabs. Ensure the patio slabs have been cleaned of any dust or debris by simply brushing down or washing with clean water. Ensure you have carried this out for your entire batch of paving slabs before you start priming.
Step 2 - Mixing
Pour 7 litres of clean water into a large container. Add UltraScape pro-prime powder slowly and mix for 3 to 5 minutes to create a smooth, lump-free slurry. Your Primer is now ready to use.
Step 3 - Priming
Start to apply your paving primer liberally by using a small paint brush and aim to coat the back of the paving slab with 1-2mm of the primer. Once you're happy that the entire surface area is coated with primer, immediately place your paving slab in place onto the prepared mortar bed. Repeat this process across your paving tiles.
Step 4 - Storage
If you have any of this powdered substance left, you can store this back in its tub, provided there is no water present. You can store this for up to 8 months in a cool, dry place.
We have many Paving Accessories within our large range of landscaping supplies, including Paving Jointing Grout, Paving Cleaner and Natural Stone Sealer.

What is the Difference Between Porcelain and Sandstone?
When selecting paving materials for your outdoor spaces, Porcelain and Sandstone offer distinct qualities suited to different preferences and requirements.
Porcelain Paving
Porcelain is a manufactured material designed to replicate the aesthetic of natural stone while delivering superior durability and minimal maintenance. Its production involves vitrification, where pure clays and minerals like quartz are heated to temperatures exceeding 1200°C. This process results in:
Durability: Porcelain slabs are exceptionally strong, resisting scratches, stains, and wear over time.
Non-Porous Surface: Being waterproof and resistant to mold, moss, and frost makes Porcelain ideal for wet climates or areas around pools.
Minimal Maintenance: Unlike natural stone, Porcelain retains its texture and color without sealing, requiring only basic cleaning.
Safety: With an R11 skid rating, Porcelain provides excellent grip even in wet conditions, ensuring safety in high-traffic or family-friendly areas.
Modern Aesthetic: Its refined, sleek appearance works well in contemporary garden designs.
Sandstone Paving
Sandstone, a natural material sourced from quarries (primarily in India), exudes a traditional, rustic charm. Its distinctive riven texture and natural variations make it a popular choice for homeowners seeking a timeless appeal.
Eco-Friendly: Sandstone’s porous nature allows rainwater absorption, aiding in natural drainage and potentially reducing flood risk.
Natural Aging: Over time, Sandstone develops a weathered patina, appealing to those who enjoy a vintage or aged aesthetic.
Maintenance: Regular sealing is needed to preserve its colors and protect against weathering. Without sealing, its hues gradually fade to softer, lighter tones.
Traditional Look: Sandstone’s textured finish and natural variations add warmth and character to outdoor spaces.
Comparative Overview

Maintenance Low—easy to clean, no sealing needed High—regular sealing to maintain color

Choosing the Right Option
Your decision should align with your aesthetic goals, maintenance preferences, and environmental considerations:
Opt for Porcelain Paving for a modern, sleek look with minimal maintenance and long-term durability.
Choose Sandstone Paving for a traditional, natural vibe with environmental benefits and a rustic charm.
Both materials bring unique advantages, allowing you to tailor your choice to your lifestyle and outdoor needs.
