CRACK REPAIR PRINCIPLES
Fiberdine’s technical paper classifies cracks by width as a practical guide because the resin properties and repair approach required can differ. Actual selection should also consider possible resin loss and substrate condition.
Because a larger resin volume is involved, the risk of resin loss or deformation increases. A relatively high viscosity and shorter cure time may therefore be required, with the method selected to suit the site condition.
Site assessment takes priorityThe concept is to retain resin inside the crack while allowing post-injection penetration into finer areas. TD-Cartridge uses 2 mm or more as the guideline for pressure injection.
View TD-Cartridge ↗Low viscosity and penetration are important because resin needs time to enter the fine crack. CP-10 is used for hairline cracks up to 0.5 mm without special pressure-injection equipment.

TD-Cartridge uses 2 mm or more as the guideline for pressure injection.The technical paper describes a method using M-1 and penetrating crack adhesive CP-10 without special pressure-injection equipment.
In one documented test using an approximately 0.2 mm hairline crack, resin penetration across almost the entire internal crack was recorded in about eight minutes after application. This is a test-condition result, not a jobsite performance guarantee.APPLICATION PROCEDURE
Review the sequence from work-area selection and substrate preparation through resin application, reinforcement-fiber placement, consolidation and topcoat. Crack repair, when required, is selected separately and completed beforehand.
TAC DINE resin, reinforcement fibers and a scale when dividing resin into smaller batches.
Work gloves / mask, wire brush, masking materials and a grinder when required.
Roller, rubber spatula, brush and other auxiliary items appropriate to the work conditions.
Decide whether reinforcement will be partial or full-area. For partial work, the source procedure uses a work area extending at least 30 cm beyond both ends of the crack.
Remove loose decorative mortar or weak material, smooth the surface with a wire brush or equivalent, and remove dust and contamination. Protect adjacent areas from resin.
Apply primer to the prepared surface. PS-10(G) is currently out of production. For this primer step, use solvent-free PE-10GⅡ after confirming the current product documents and site conditions.
Where the foundation has a major defect, fill it after primer treatment and restore a smooth surface.
Apply resin to form the bonding base for the reinforcement fiber. PE-10GⅡ or AC-100Ⅱ are identified as resins used with the reinforcement fibers; use a roller to create a uniform layer suitable for fiber impregnation and adhesion.
Follow the applicable product specification and application conditions for material selection and resin quantity.
Place the reinforcement fiber before the base coat cures. Press the sheet lightly into position and confirm resin penetration from behind the sheet.
Remove air from behind the sheet and consolidate the reinforcement layer. Use a de-airing roller or other suitable method when required so resin is distributed through the fiber layer.
Apply resin over the reinforcement fiber so the fiber layer is integrated between the resin layers. During cure, protect the surface from contact and from rain or water when exposure is possible.
Keep the finishing process separate from the core reinforcement sequence. AD-20 can be used when a mortar finish is specified.
