Application Stages

How This System Helps Reduce Old Tile Overlay Risks

Old tile overlay waterproofing risks often come from dense glazed tile surfaces, weak bonding, dust, oil, cleaning residue, loose tile areas, open joints, grooved joints, cracked or hollow tiles, drain edges, wall-floor corners, door thresholds, exposed surface wear and peeling risk at weak edges. This system uses BW6-9527 blended with quartz sand for joint filling and local repair, BW8007 as the adhesion interface coat and BW8032 as the exposed surface overlay to help improve bonding, reduce weak joint paths and create a continuous protective finish over the prepared old tile surface.

Old tile cleaning and joint grooving preparation before BW6-9527 joint filling and polyaspartic overlay
01

Old Tile Surface Cleaning and Joint Grooving

Clean the old tile surface, remove dust, oil, loose material and weak areas, then groove or open tile joints where needed. This step helps reduce bonding failure caused by contamination, dense glazed surfaces, untreated gaps and weak tile edges.

Reference: cleaning, drying, joint opening, edge checking and removal of weak or hollow areas should be confirmed before product coating work. Loose, hollow, severely cracked or unstable tiles should be removed, repaired or mechanically fixed before the overlay system is applied.
02

BW6-9527 Quartz-Sand Joint Filling / Repair

Blend BW6-9527 with quartz sand for grooved tile joint filling, gap treatment and local repair. This step helps reduce leakage paths through open joints, cracked joints, small voids and local weak points before the adhesion interface coat is applied.

Reference: BW6-9527 product data lists about 0.7 kg/m2 at 500 um. When blended with quartz sand, final joint filling consumption depends on joint width, groove depth, sand ratio and repair scope.

03

BW8007 Adhesion Interface Coat

Apply BW8007 as the adhesion interface coat to improve bonding between the prepared old tile surface and the following BW8032 overlay coat. This step helps reduce peeling risk over dense tile surfaces and supports a more stable overlay connection.

Reference: BW8007 product data lists about 0.08 kg/m2 at 40 um, with recommended DFT of 20-40 um. Final consumption depends on tile absorption, surface texture and application method. BW8007 official product packaging for old tile adhesion interface coat Product usedView BW8007 ->

BW8032 Polyaspartic Surface Overlay Protection

Apply BW8032 to form the exposed waterproofing, protection and decorative overlay surface over the prepared old tile system. This step helps reduce exposed surface wear, water contact, staining and weak surface finish issues after renovation.

Reference: about 1.2 mm / about 1.80 kg/m2 for BW8032 surface overlay protection. Final consumption depends on tile absorption, surface texture, color requirement, application method and project specification.

Quality control

Application & Quality Control

Quality control should focus on tile-surface readiness, joint filling stability, BW8007 adhesion coverage and BW8032 overlay continuity before handover.

01

Tile Surface Readiness

Confirm the existing tile surface before product application starts.

  • Loose tile and hollow-area review
  • Dust, oil and contamination removal
  • Joint opening and cleaning
  • Dry and compact prepared surface
02

Joint Filling and Adhesion Interface

Control the transition from joint repair to interface bonding.

  • Stable BW6-9527 quartz-sand filling
  • No untreated gaps or weak repairs
  • BW8007 coverage over prepared tile
  • Recoating window checked before BW8032
03

Surface Overlay Protection

Review the exposed BW8032 overlay before handover.

  • Continuous surface coverage
  • Color and finish consistency
  • No pinholes, peeling or weak edges
  • Detail and edge continuity
Inspection focus
  • Tile joints and gaps
  • Local repair zones
  • Prepared dense tile surface
  • Adhesion interface coverage

  • Color and finish review

Suitable project conditions

Suitable Old Tile Overlay Conditions

Use this section to check whether the project fits a BW6-9527 + BW8007 + BW8032 old tile overlay renovation system before final specification.

  1. 01

    Old Tile Surfaces for Overlay Renovation

    Existing tile surfaces can be reviewed when the tile layer is stable enough for cleaning, joint opening, repair, adhesion interface and overlay protection.

    Check before specification: tile stability / cleaning / adhesion

  2. 02

    Open Joints, Gaps and Local Weak Areas

    Projects with visible joints, gaps or small repaired areas can use BW6-9527 blended with quartz sand for joint filling and local repair before overlay work.

    Check before specification: joint width / groove depth / repair scope

  3. 03

    Dense Ceramic Tile Bonding Risk

    Dense old tile needs adhesion-interface review before the surface overlay coat is applied.

    Check before specification: surface profile / dryness / compatibility

  4. 04

    Exposed Decorative Protection Need

    BW8032 can be reviewed where the old tile face needs a continuous exposed protective finish with waterproofing and decorative renewal goals.

    Check before specification: color / finish / service exposure

Do not count old tile surface cleaning or joint grooving as product coating layers. The product build-up starts from BW6-9527 quartz-sand joint filling, then BW8007 adhesion interface and BW8032 surface overlay protection. The system should not be applied directly over unstable tile areas.

FAQ

FAQ

Common questions about using BW6-9527, BW8007 and BW8032 for old tile overlay renovation.

What is this old tile overlay system designed for?

It is designed for old tile surface renovation where the project needs joint treatment, adhesion over dense tile and an exposed polyaspartic overlay surface without removing the entire tile layer.

Is joint grooving counted as a coating layer?

No. Joint grooving is substrate preparation. The product build-up starts from BW6-9527 blended with quartz sand for joint filling and local repair.

Why is BW6-9527 blended with quartz sand?

BW6-9527 blended with quartz sand is used to fill grooved tile joints, gaps and local repair areas before the overlay system is applied.

What does BW8007 do in this system?

BW8007 is the adhesion interface coat. It helps improve bonding between the prepared old tile surface and the following BW8032 overlay coat.

What role does BW8032 play?

BW8032 forms the exposed overlay surface for waterproofing, surface protection and decorative renewal over the prepared tile surface.

Does this system remove the entire old tile layer?

No. The page is focused on overlay renovation. The old tile surface must still be checked for stability, cleanliness and repair needs before coating.

Can exact consumption be fixed before seeing the tile surface?

No. Planning consumption depends on joint width, groove depth, tile absorption, surface texture, color, application method and project requirements.

What information helps before requesting a quote?

Tile area, tile stability, joint width, groove depth, local repair scope, moisture condition, target color, service exposure, application method, location and timeline are useful for review.
