MR. JO EP Grout – CMR
MR. JO EP Grout – CMR Chemical-resistant epoxy grout for aggressive environments — protect foundations where spills attack concrete
The problem — chemical exposure shortens foundation life
In chemical plants, plating shops, battery rooms, dairy/food facilities and many industrial production lines, accidental spills (acids, alkalis, solvents) or regular washdowns can attack cementitious grouts, leading to:
- Rapid degradation of grout and concrete,
- Loss of bond and local undermining of baseplates,
- Corrosion of anchors and increased safety risk, and
- Costly premature repairs or shutdowns.
A standard epoxy grout may resist mechanical stress but not all chemistries; some sites need specific chemical resistance.
The solution — why MR. JO EP Grout – CMR
EP Grout – CMR is formulated for machine foundations that are regularly exposed to aggressive chemicals. It combines the mechanical strength and load transfer properties of epoxy grouts with enhanced chemical resistance, protecting both the foundation and the machinery from spill-related damage.
Use CMR when your foundation faces corrosive liquids, regular acid/alkali washdowns, or environments where spill containment is imperfect.

Job-ready workflow (site practical)
- Evaluate exposure — document the chemical types, concentrations and likely exposure frequency. This informs whether CMR is suitable and any additional protective steps (e.g., coatings).
- Surface prep — as with STD, ensure concrete and metal are clean and sound. For chemically contaminated sites, extra cleaning cycles or neutralization may be required.
- Mixing & placement — CMR is also a 3-component system; follow exact mixing instructions. Because chemical resistance depends on proper cure, obey mix ratio, mixing time and curing conditions.
- Pour & vent — ensure full contact under base plates and avoid voids. For aggressive environments consider a top seal/coating over grout (if specified) to improve long-term resistance.
- Cure & validate — allow full cure as per TDS before exposing to chemicals or washdowns. Consider testing a small exposed sample if unusual chemistries are present.

Practical tips & dos/don’ts
Do:
- Do run compatibility checks if you expect exposure to exotic solvents — consult technical data.
- Do protect newly grouted areas from immediate aggressive exposure until full cure.
- Do combine with secondary seals (if spec’d) for extreme exposures.
Don’t: - Don’t assume all epoxy grouts are equal — CMR’s chemistry gives superior chemical resistance; use it where needed.
- Don’t expose to concentrated chemicals during early cure.
Troubleshooting
- Surface attack after exposure → inspect for premature exposure; check if cure was complete or if chemicals are outside recommended resistance list.
- Finish softening → verify chemical concentration and consider additional protective coating.
ROI — protect your assets & reduce surprises
Using a chemically resistant grout prevents progressive foundation deterioration, reduces unplanned outages and avoids secondary damage to anchored equipment. For chemical-exposed facilities the investment in CMR minimizes safety and replacement costs.
