Assess the cause
Start with wide photos, joint close-ups, your postcode and access details. Slab movement, pooling water and damaged bedding need assessment before joint replacement is agreed.

Failed joints in natural stone paving
Natural stone and Indian sandstone patios can develop open or cracked joints while the slabs themselves remain usable. Repointing may suit sound paving, but moving slabs, flaking edges or settlement need checking before the old filling is removed.
Indian sandstone is not one uniform product. Slab finish, thickness and porosity can vary. Tell us about known sealers and previous treatments; do not assume a cleaning or jointing product that suited another patio will suit yours.
What matters before choosing a stone joint finish
- Check narrow, broad and irregular joints against the proposed product’s width and depth limits.
- Identify fragile edges before raking out; aggressive preparation can damage the stone.
- Check whether the bedding and drainage are compatible with any proposed permeable joint system.
- Discuss residue control and a suitable small-area test where staining is a risk.
How the work is assessed and planned
Prepare sound joints
Where repointing is suitable, failed filling needs appropriate removal without damaging slab edges. Clean the surface and joints using a method suited to the paving, keep outlets clear and check the required joint depth.
Choose and apply a compatible system
Agree the material after checking the paving, bedding and joint sizes. Follow that product’s preparation and application requirements rather than choosing on colour alone.
Protect the finish
Weather, drying and curing requirements determine the work sequence. Keep people and pets off for the advised period and follow the agreed aftercare before washing or moving furniture back.
Which jointing material is suitable?
There is no single material that suits every patio. The options below are subject to inspection; they are not a specification for your paving.
Sand and cement / mortar-based pointing
A compatible sand-and-cement or proprietary mortar system can give a firm traditional joint on suitable rigidly laid paving. It needs careful mixing, depth and finishing; a rigid joint can crack if the slabs move, and careless application can mark porous stone. A thin skim over failed joints is not a repair.
Resin and brush-in jointing compounds
Some resin-based compounds are brushed into prepared joints, which can make application practical on suitable paving. Brush-in describes the method, not one universal chemistry: products vary in drainage, bedding, width, depth and weather requirements. Poor compatibility or preparation can cause failure, and residue can mark some surfaces. The actual system is agreed after inspection.
Colour and surface finish
Choose from suitable systems only after compatibility is checked. Wet stone can look very different from dry stone, and new joints may not match weathered pointing exactly.

Questions about natural stone and Indian sandstone patio repointing
Can Indian sandstone use a resin jointing compound?
A compatible product may be an option, but the joint sizes, bedding, drainage and stone finish must meet its requirements. It should not be selected solely because the paving is described as Indian sandstone.
Can preparation damage sandstone edges?
Yes, unsuitable removal methods can chip or mark slab edges. The condition of the stone and existing filling needs assessment before the preparation method is agreed.
Will repointing fix loose slabs?
No. Joint replacement does not repair unstable bedding or reset paving levels. Moving, sunken or rocking slabs need assessment first; the scope of any separate repair must be agreed before repointing.
Can you choose the material from a photo?
Photos help with initial advice, but joint dimensions, bedding, drainage and the paving material may need an inspection. No particular brand or system is promised before suitability is checked.
