Applying microcement over existing tiles can reduce demolition and avoid changing floor levels as much as a full replacement. It is possible in many settings, but only when the tiled surface is stable, well bonded and properly prepared.
Covering loose tiles or active cracks simply transfers the weakness into the new finish. A site survey should determine whether the existing surface is a suitable substrate or an obstacle that needs removal.
Tailored Surface Designs installs Forcrete microcement for homes and businesses across Shipley and West Yorkshire.
Check Whether the Tiles Are Sound
Tiles should be firmly bonded without hollow, rocking or loose areas. The substrate beneath them also matters; movement in boards or screeds can continue through the finish. The installer may use visual, tapping and local investigation methods before deciding whether overlay is appropriate.
Identify Cracks and Movement Joints
A crack through several tiles can indicate movement below rather than a damaged surface alone. Structural and movement joints need appropriate treatment and may remain expressed through the system. Bridging active movement with a rigid decorative finish risks a visible crack later.
Clean and Degrease Thoroughly
Kitchen and bathroom tiles can retain grease, soap, polish or cleaning residues that interfere with adhesion. Preparation needs products and methods compatible with the microcement system. Simply wiping the tiles or roughening a contaminated surface does not create a dependable bond.
Create the Required Mechanical Key
Glossy tile faces are not normally suitable for direct coating. The surface is mechanically prepared and primed according to the system, with dust removed carefully. The objective is consistent adhesion, not random scratches that leave smooth areas between them.
Level Grout Lines and Texture
Grout joints and tile edges can show through thin decorative coatings if they are not treated correctly. Base layers and reinforcement create a more uniform substrate. Deep texture, lippage or small mosaic tiles may require more preparation and can change whether overlay remains cost-effective.
Plan Floor Heights and Doors
Microcement adds only a small build-up, but primers, reinforcement, base coats and finish still raise the surface. Check doors, appliances, thresholds, drains, skirtings and transitions to other rooms. A few millimetres can matter around fitted kitchens and level-access showers.
Coordinate Wet-Area Waterproofing
Existing tiles are not proof that the substrate beneath is waterproof or in good condition. Showers and wet rooms need a compatible waterproofing strategy, especially at drains, corners and penetrations. The installer should confirm how the overlay integrates with existing or new tanking.
Know When Tile Removal Is Better
Remove tiles where they are loose, contaminated, badly uneven or covering a weak substrate. Demolition can also be preferable when services, drainage or waterproofing need major changes. A responsible installer should recommend removal when overlay would only conceal a problem and transfer risk to the finished surface.
What to Prepare Before Requesting a Quotation
A useful quotation begins with accurate information. Photos and measurements can help an initial conversation, but they do not replace a survey where condition, access, compliance or hidden construction affects the recommendation. Prepare:
- the outcome you want and the problem you need to solve
- relevant photographs, drawings, manuals or previous reports
- known defects, changes and earlier repair or installation history
- access limits, operating hours and important programme dates
- questions about scope, exclusions, warranties and aftercare
Ask a Specialist to Assess Existing Tiles
Tailored Surface Designs can inspect tile condition, joints and surrounding details before proposing a Forcrete microcement build-up. Homeowners across West Yorkshire can then compare overlay with full removal using the actual substrate rather than an assumption.
