- Ready-to-Use Product Features
- Product Highlight
- Often specified as a resurfacer, the material acts as an enhancement to any subsequent epoxy topcoat systems.
- With a resinous open crosslink during initial gel-time it serves as a bonding layer and crosslinking system, boosting the adhesion of epoxy top coats and making any system cohesively improved and better performing in combination; the mortar serves as a self-priming underlayment, top-coated with a variety of high performance epoxies for use when dealing in extremely aggressive environments.
- Mortartec Ceramico is a high-performance solution for lining, surfacing/resurfacing, patching and filling voids and bug holes on concrete substrates.
- The mortar may be hand or spray applied, typically from 1/16” to 1” in depth.
- Uses include repairing concrete walls, ceilings, lining brick or concrete infrastructure, etc.
- Mortartec Ceramico provides an extremely dense matrix and will accept coatings at earlier stages than typical Portland cement repair products.
- Features
- Advanced epoxy-modified-cement technology
- Next generation, acid resistant mortar (surpassing calcium aluminate)
- Mitigation of MVT and outgassing
- Same day recoat / top coat (-3 hours after applied)
- Incredible adhesion
- Self-priming open resinous cross-link for top coat bond optimization
- No need for further preparation after cure
- Ultra-thin film capability (1/16"), up to 1" per p
- "Green" concrete resurfacing solution
Applications & Uses
- Applications
- Application Area
- Application Method
- Typical Uses
- Industrial infrastructure repair / resurfacing
- Sanitary sewers/ manholes/ lift stations
- Water+wastewater treatment plants
- Repair mortar and/or total substrate resurfacer for concrete to aid in top coating and lining.
- Surface Preparation
- Remove all loose concrete, brick or mortar from affected areas by mechanical means.
- Surfaces shall be free of paints, oils, dirt, dust, curing compounds, sealers, form release agents or any material that would prevent mortar from coming into contact with the open pores of the concrete.
- Shot blasting, abrasive blasting, chipping and high-pressure water cleaning (5,000 psi min.) are all excellent surface preparation methods.
- Smooth concrete surfaces may require etching.
- Dampen area to achieve a saturated, surface dry condition (SSD).
- Substrate should remain moist, SSD as much and as long as possible until the application.
- Prepare concrete to remove laitance, form release agents, curing compounds, sealers and other contaminants and to provide surface profile in accordance with SSPC-SP13/NACE 6, ICRI CSP5.
- To repair large bugholes, and spalls, coarse aggregate or preapproved fillers may be added.
- Mixing
- Pour liquid Part B into a container large enough to hold all components.
- With agitation slowly add Part A.
- When blended, slowly sift powder, Part C, while continuing agitation.
- Do not dump all of the Part C into the liquids at one time.
- Mix for at least two minutes or until the cement-sand is thoroughly wetted and a smooth consistency is obtained.
- Important: Do not add additional Part C.
- Application Method
- Allow new concrete to cure 28 days, or until compressive strength has reached accepting levels.
- Verify dryness by testing for the presence of moisture with the “Plastic Film Tape- Down Test” (Reference ASTM D4263) or by other industry-acceptable methods.
- When moisture is detected on horizontal surfaces, perform “Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride” (Reference ASTM F1869).
- Moisture content not to exceed three pounds per 1,000 sq.ft.in a 24 hour period.
- Then proceed to mix, apply, and finish.
- If within recoat times, no preparation is required for subsequent lifts or top coats.
- Coverage
- Allow for wastage due to surface irregularities porosity.
- Maximum performance is obtained when the product is expertly applied as a continuous, void-free film.
- When using Mortartec CeramicoTM, surface should be “pre-wet” or dampened with potable water to a Saturated Surface Dry (SSD) condition; the concrete is darkened by water but there is no pooling on the surface.
- Do not oversaturate the surface.

- If Mortartec CeramicoTM begins to thicken in pail during use when applying by hand, do not add more water.
- Simply reagitate with drill to bring back original creamy texture.
- Because Mortartec CeramicoTM is waterborne epoxy modified, while spraying, it is possible to add additional water in measured quantities without affecting performance as spraying cause some loss of moisture.
- Up to 6oz of additional water can be safely added, if Mortartec CeramicoTM is being transferred with low-pressure spray application.
- Use only potable water.
- Equipment
- Mortar hawk, steel, concrete finishing trowels, broad knives and rubber floats are recommended.
- Material can be transferred to the surface by utilizing hydraulic spray equipment (i.e. Graco M680 or S340e Mortar Pump or a 9:1 WIWA 410 pump) followed by troweling to seal the material.
- For a smoother finished appearance, trowel licks may be reduced by using a dry sponge to smooth out the Mortartec CeramicoTM material.
- Note: If white liquid is brought to the surface during this process, material is being overworked and/or oversaturated.
- Overworking or oversaturating the surface may have an adverse effect on the adhesion of subsequent coatings applied.
- If this is evident, then allow for Mortartec CeramicoTM cure and remove surface deposit using concrete rub brick, or another applicable method.
- Limitations
- Surface temperatures must be no higher than 110°F during application, and no less than 65°F.
- Protect from rain until initial set has been achieved.
- To avoid flash setting, do not contaminate Mortartec CeramicoTM with other type cements.
- Minimum thickness: 1/16 inch
- Maximum thickness: 1 inch per pass, if rebuilding requires more depth, wait for the gel time to set in order to hang multiple coats in successive applications (1/2 hr at 85F)
- Note: For alternative repair methods of large spalls and other cavities deeper than the recommended maximum thickness, contact Epoxytec.
- Recoat windows start as soon as gel begins (typically 2 hours minimum at 77°F), do not exceed 36 hours @ 77°F for recoat or tie-in top coats.
- Consult with Epoxytec for detailed instruction applying to “green” concrete.
