Why Fossil Mint Indian Sandstone Is So Popular in UK Gardens
Fossil Mint Sandstone works with almost every garden style. Its creamy beige colouring complements red brick, grey render, timber decking, and cottage planting equally well. Because it is naturally calibrated to a consistent 22mm thickness, every slab sits level without constant adjustment, saving hours of laying time.
It also brightens naturally after pressure washing, so it looks as good after ten years as it did on day one. To understand what makes sandstone such a durable and long-lasting choice, read our guide on everything you need to know about sandstone for paving.
Which Fossil Mint Paving Slabs Should You Choose?
This is a question most buyers ask before they order, and the answer depends entirely on the look you want.
If you prefer a contemporary, smooth finish with clean sawn edges that suit modern garden designs, the Fossil Mint Smooth Sandstone Mixed Patio Sawn Edged Paving Slabs are the perfect choice.
If you prefer a more natural, traditional finish with the characterful surface texture that Indian sandstone is famous for, the Fossil Mint Riven Sandstone Mixed Patio Paving Slabs deliver that authentic outdoor feel. The natural riven surface also provides excellent slip resistance, which matters greatly in wet UK conditions.
Both ranges come in mixed patio packs with complementary slab sizes already calculated for you, so there is no guesswork on quantities.
What You Need Before You Start
Materials: Fossil Mint Paving Slabs, MOT Type 1 sub-base, sharp sand, cement, bonding primer, flexible jointing compound, and an impregnating stone sealer.
Tools: Rubber mallet, spirit level, tape measure, string line, wacker plate, wet saw, safety goggles, and gloves.
Always order 10% extra slabs to cover cuts and any breakages. For low maintenance border areas alongside your new patio, the Kandla Grey 600x900 Outdoor Porcelain Paving pairs beautifully with Fossil Mint Sandstone and requires zero sealing.
How to Lay Fossil Mint Sandstone Paving Slabs Step by Step
Laying Fossil Mint Indian Sandstone is a straightforward process when you follow the right order. Work through each step below carefully and you will have a level, long-lasting patio that looks professionally finished.
Step 1: Prepare the Ground Correctly
Dig down 150mm for a standard patio or 200mm where vehicles may cross. Compact the soil firmly with a wacker plate, add 100mm of MOT Type 1 sub-base, and compact again. Build in a 2% drainage fall away from your house, roughly 20mm of drop per metre. Without this fall, water pools on your Fossil Mint Indian Sandstone and creates algae and frost damage very quickly.
Step 2: Mix the Mortar Bed
Use a semi-dry mix of 4 parts sharp sand to 1 part cement. It should hold its shape when squeezed but never feel wet. Lay it at 40 to 50mm deep. Never use a full wet slurry mix on pale stones like Fossil Mint Sandstone Paving Slabs as it causes permanent brown staining. Apply bonding primer to the back of every slab before placing it on the bed.
Step 3: Lay the Slabs
Start from a fixed corner against the house and use a string line to keep rows straight. Place each Fossil Mint Paving Slab firmly onto the mortar, tap level with a rubber mallet, and check both directions with a spirit level. Keep joint gaps between 10mm and 15mm throughout. Work in small sections of around two square metres at a time so the mortar bed does not skin over before the slabs are placed.
For cuts around edges and curves, a wet saw gives the cleanest result. Our guide on the best way to cut slate paving slabs covers cutting techniques that apply directly to sandstone too.
Step 4: Joint and Point Properly
After 24 hours, brush a flexible jointing compound into all gaps and compact it down. Never use standard cement pointing on Fossil Mint Indian Sandstone as it cracks in winter and leaves grey staining across the pale surface. A flexible compound moves with the stone through seasonal temperature changes and stays watertight year after year.
Step 5: Seal the Stone
Apply two coats of a quality impregnating sealer to completely dry slabs. This protects Fossil Mint Sandstone from oil, algae, frost, and food spills, keeping the warm cream colour looking vibrant. Allow each coat to dry before foot traffic.
Once sealed and in use, learn how to pressure wash sandstone paving safely without damaging the surface or stripping the sealer.
How Long Does Fossil Mint Indian Sandstone Actually Last?
Fossil Mint Sandstone Paving Slabs are extremely durable and low maintenance when installed on a suitable sub-base that is compacted and drained and a good sealer used. It is a naturally dense and frost-resistant stone which is important for the UK climate because freeze-thaw conditions in winter can be a major cause of paving failure.
What helps them last is a good sub-base, the right consistency of mortar, good drainage fall, using flexible jointing rather than cement and re-sealing every 3-5 years. If you follow those five points your Fossil Mint Paving Slabs will look great for at least another 15 years.
Common Mistakes to Avoid
Too wet a mortar mix stains pale Fossil Mint Sandstone permanently. Skipping the bonding primer causes slabs to lift within months. Laying directly on compacted soil with no sub-base leads to sinking and cracking. Ignoring the drainage fall allows water to pool and encourages algae growth. Pointing too soon before the mortar cures fully leads to cracked joints by the following winter. Avoiding all five of these mistakes is the difference between a patio that lasts two decades and one that needs relaying within three years.
Summary
Laying Fossil Mint Indian Sandstone correctly takes preparation, the right materials, and attention to a few key details. Nail the sub-base, use a semi-dry mortar, keep joint gaps consistent, use flexible jointing compound, and seal the finished surface. Do those five things and your Fossil Mint Paving Slabs will look exceptional for the next 20 years.
