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.

Cracked grout, missing joints or residue on porcelain?
Outdoor porcelain paving needs a compatible exterior jointing system, not a product chosen just because it is called grout. Narrow gaps, movement joints and the underlying construction can make this a different job from repointing broad-jointed stone slabs.
Cracking along a joint can reflect movement below the surface. A loose tile or slab needs assessment before replacement grout is applied. Grout haze on the face is also different from failed material within the joint.
A porcelain-specific assessment
- Send a slab label or supplier details if available; appearance alone may be misleading.
- Measure representative gaps and show existing movement joints and perimeter details.
- Identify residue on the face separately from cracks or voids in the joint.
- Do not use acid cleaners or abrasive tools on an unidentified surface to prepare for a quote.
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.
Exterior cementitious grout
A compatible exterior-rated grout may be suitable if the joint dimensions and construction meet its requirements. Product selection and residue removal need care.
Resin or epoxy options
A resin-based or epoxy system may be considered where the manufacturer approves the application. It is not automatically the right choice, and working time and cleanup requirements differ.
Movement joints
A designed movement gap is not an ordinary failed grout joint. It must be identified and treated appropriately rather than filled rigidly with the rest of the patio.

Questions about porcelain patio grouting and joint repair
Can all gaps in porcelain paving be grouted?
No. Designed movement joints and perimeter details must be identified rather than filled rigidly. Ordinary joints also need the correct width, depth and compatible exterior material.
Is grout haze the same as failed grout?
No. Haze is residue on the paving face; failed grout concerns the joint itself. Cleaning compatibility and the need for joint replacement must be assessed separately.
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.
