Ceilcote 748 Epoxy Grout
Ceilcote 748 is a three-component chemical resistant epoxy grouting material. It provides high strength, good adhesion to concrete and steel, minimal shrinkage and resists degradation by corrosive chemicals.
- Excellent Chemical Resistance
- Low Exotherm
- High Strength
Ceilcote 748 Corrosion Grout, Chemical Resistant Epoxy Machinery Grout
Ceilcote 748 Corrosion Grout is a three-component, silica-filled, polyamine-cured epoxy grout from International Protective Coatings, an AkzoNobel brand. It is used under chemical pumps, process equipment, storage tanks, machinery, structural steel, and pedestals where the grout has to carry load and stand up to corrosive splash. The cured grout develops high compressive strength, bonds to concrete and steel, and shows low creep under sustained load, with a low exotherm during placement. Splash and spill resistance covers common acids, alkalis, solvents, and hydrocarbons. International supplies 748 in 0.4 and 1.6 cubic foot units. Ceilcote 749DP is a separate deep-pour epoxy grout for large volumes and virtually unlimited pour depth, not the same 748 chemistry. Use Ceilcote 749DP Grout 2.0 cu ft when the job needs that deep-pour system.

Frequently Asked Questions
What is Ceilcote 748 Corrosion Grout?
It is a three-component, silica-filled, polyamine-cured epoxy grout for chemical pump pads, process equipment, storage tanks, machinery, structural steel supports, and pedestals. It provides high strength, adhesion to concrete and steel, minimal shrinkage, and resistance to corrosive chemicals.
How is Ceilcote 748 different from Ceilcote 749DP?
They are related Ceilcote epoxy grouts, not the same material. 748 is the standard chemical-resistant corrosion grout (manufacturer pour depth not to exceed 4 inches per lift; multiple pours for greater depth). Ceilcote 749DP Grout 2.0 cu ft is a separate deep-pour system designed for virtually unlimited pour depths and large volumes.
What compressive strength does Ceilcote 748 develop?
The current manufacturer data sheet reports 17,000 psi (117 MPa) compressive strength by ASTM C579 Method B, 12,000 psi (83 MPa) at 170°F, and 15,100 psi (104 MPa) for the 3.5 bag mix. Tensile strength is 2,500 psi (17 MPa). Values come from the International Paint / AkzoNobel TDS (English issue 18 June 2007; Spanish USA LTR publication 1 January 2008).
What is the working time and when can equipment go back in service?
Working time is approximately one hour at 70°F (21°C). Time to service at 10,000 psi is 60 hours at 50°F (10°C), 18 hours at 73°F (23°C), and 8 hours at 90°F (32°C).
How deep can Ceilcote 748 be poured?
The manufacturer data sheet states grout pour depth should not exceed 4 inches (10 cm). Use multiple pours for greater depths. For virtually unlimited pour depth in a deep-pour chemistry, use Ceilcote 749DP Grout 2.0 cu ft.
What unit sizes does International supply for 748?
Standard packages are 0.4 cubic foot (resin 4.9 lb, hardener 2.0 lb, aggregate 46.0 lb) and 1.6 cubic foot (resin 19.5 lb, hardener 8.00 lb, aggregate 184.0 lb). Optional Ceilcote 680 Primer is packed in 1 and 4 gallon units. Minimum shelf life at 70°F (21°C) is 18 months for resin and hardener; aggregate is indefinite if kept dry.
