Westcoat EC-76 Cove Gel | 1.5 Gallon Kit
About
Create seamless, sanitary epoxy cove base for commercial kitchens, washrooms, and coated floors.
A cove at the wall-to-floor transition improves cleanability, hygiene, and long-term performance in resinous flooring environments. Westcoat EC-76 Cove Gel simplifies its installation by handling every resin stage of the process. Applied first as a tack coat, it primes the wall and the first 1 to 2 inches of floor. Blended with TC-73 Epoxy Mortar Sand or a comparable aggregate, it becomes the troweled mortar that forms the cove. After the aggregate coat dries overnight, a thin fill coat seals the aggregate texture and can be sanded smooth before the clear or pigmented topcoat.
EC-76 is the cove resin for Westcoat's epoxy floor systems, including Thin Film systems used on commercial kitchens, restaurants, washrooms, and showrooms. It dries semi-transparent and is for interior use unless protected by a UV-resistant coating. It is also specified for filling cracks in Westcoat Texture-Crete resurfacing systems.

Westcoat Systems Using EC-76
EC-76 Cove Gel is Westcoat's epoxy cove resin, used to create optional cove base at the wall-to-floor transition across Westcoat's epoxy floor systems. It is also the crack treatment in several Texture-Crete decorative systems, where it fills cracks before priming, with fine silica broadcast into the wet epoxy to give the coating a surface to bond to.

How-To
Application Instruction Overview for Westcoat EC-76
IMPORTANT! Before You Begin: Review the complete Westcoat EC-76 Technical Data Sheet (TDS) and Safety Data Sheet (SDS), linked above, along with the System Specification Sheet for the system being installed. The information below is a brief overview and does not replace Westcoat's complete application instructions.
Step 1 – Inspect and Prepare the Surface
- Surface must be structurally sound, clean, dry, and free of grease, paint, oil, dust, curing agents, laitance, or other material that will prevent proper adhesion
- Concrete should be at least 2,500 PSI and porous or rough enough to allow the product to soak in
- Concrete must cure a minimum of 28 days
- Test the slab for efflorescence, moisture, and hydrostatic pressure before starting
- Contact the manufacturer before application if moisture emissions exceed 5 lbs/1000 sq ft/24 hours (ASTM F1869) or relative humidity exceeds 75% (ASTM F2170)
- Prepare and prime the surface as specified in the System Specification Sheet for the system being installed
Step 2 – Mix EC-76
- In a clean, dry bucket, mix 2 parts A with 1 part B by volume
- Mix slowly with a mechanical mixer at low rpm for at least 3 minutes or until completely combined
- Only prepare the amount you can use in 20 minutes at 70°F
- Thinning is not recommended
Step 3 – Apply the Tack Coat
- Immediately after mixing, apply EC-76 to the wall up to the cove cap and 1 to 2 inches onto the floor
- Apply with a brush, trowel, or putty knife, completely coating the area to be coved
- No separate primer is required, as the tack coat acts as the primer
- Move immediately to the aggregate coat
Step 4 – Apply the Aggregate Coat
- Blend approximately 25 lb of TC-73 or equivalent aggregate per 48 oz of mixed EC-76, or 100 lb per 1½ gallon kit
- When using 20-30 grit silica sand, increase the resin by using approximately 75 lb of aggregate per 1½ gallon kit
- Mix with a mechanical mixer until all aggregate is completely and evenly coated
- Trowel the mix onto the wall, stopping at the cove cap
- Smooth and finish with a cove trowel, using water or solvent to lubricate the trowel
- Allow the aggregate coat to dry overnight
Step 5 – Apply the Fill Coat
- Mix 2 parts A with 1 part B by volume in a clean container
- Apply with a sponge float or brush to fill the aggregate before the clear or pigmented topcoat
- Apply as thin as possible, smoothing out all brush and trowel marks
- EC-76 can be sanded before topcoating to ensure a smooth finish
Step 6 – Topcoat and Clean Up
- Dry time is 4 to 5 hours
- Topcoat as soon as EC-76 is tacky but does not pull up
- Remove uncured material with solvent
- Cured material can only be removed mechanically or with an environmentally safe solvent
Installation Limitations
- For professional use only
- Do not apply below 50°F or above 90°F
- Be aware of the pot life of mixed epoxy
- Cure a minimum of 24 hours before contact with water
- For interior use only unless protected by a UV-resistant coating
- Do not allow Westcoat products to freeze
FAQs
What is EC-76 Cove Gel used for?
EC-76 is used to create epoxy cove base at the wall-to-floor transition, serving as the tack coat, aggregate coat, and fill coat. It is also specified for crack treatment in several Westcoat Texture-Crete systems.
Where is EC-76 cove base used?
EC-76 adds epoxy cove base to floors in spaces such as commercial kitchens, restaurants, washrooms, and showrooms, where a seamless wall-to-floor transition makes cleaning easier.
Do I need a primer before applying EC-76 Cove Gel?
No primer is required for the cove itself, because the EC-76 tack coat acts as the primer. The floor should still be prepared and primed as specified for the system being installed.
What aggregate can I mix with EC-76?
EC-76 can be used with TC-65 Quartz Sand, TC-73 Epoxy Mortar Sand, B-23, or silica sand. A 1½ gallon kit is typically blended with about 100 lb of TC-73, while 20-30 grit silica sand requires more resin, at about 75 lb per kit.
How much EC-76 do I need for a cove?
For a 6 inch cove, a 1½ gallon kit blended with 100 lb of TC-73 yields approximately 120 linear feet of aggregate coat. You will also need material for the tack coat (about 225-250 LF per gallon) and fill coat (about 200-225 LF per gallon), and coverage changes with cove height.
How soon can I topcoat over EC-76?
Let the aggregate coat dry overnight, then apply the fill coat. You can topcoat as soon as the fill coat is tacky but does not pull up.
Can EC-76 Cove Gel be used outdoors?
EC-76 is for interior use only unless it is protected by a UV-resistant coating.
What is the shelf life of EC-76?
EC-76 has a shelf life of 2 years in unopened packaging. Do not allow it to freeze.
