Hychem Epoxy Glaze 2 — Protective epoxy coating for concrete

Epoxy Glaze 2 is usually applied by roller.

Apply 2 coats at 6–8m² per litre

Dry film thickness approximately 140µm per coat.

Temperature and the surrounding atmosphere play a part in the curing process of epoxy coatings. Under conditions of lower temperatures and higher humidity the final finish can be adversely affected resulting in low gloss or in more severe instances a white film over the surface after contact with water. Adhesion can also be affected.

To minimise an unsatisfactory cure the following indicative application conditions should be observed with respect to temperature and humidity levels:

21°C and less than 85% humidity 10°C and less than 75% humidity

Attention also needs to be paid to the substrate temperature which should be at least 3°C above the dew point during the curing phase.

Approximate application data for 23°C and 75% relative humidity.

• Concrete substrate shall be firm, clean and dry with a compressive strength of 25 MPa and surface tensile strength of 1.5MPa minimum.
• New concrete must be allowed to cure for a minimum of 28 days.
• Repair imperfections (holes and cracks) with an epoxy patching compound such as Hychem GP where necessary.
• Remove surface laitance, contaminants, coating, curing compound and all weak and loose materials.
• Prepare concrete surface by water blasting or diamond grinding to provide the appropriate surface profile for optimum mechanical keying.

• Mix with a jiffy mixer at a speed of 500rpm to avoid incorporating excessive air into the mix.
• Mix for 1 minute, scrape down the sides of the mixing container and mix for another minute to ensure the mix is homogeneous.

• Apply by brush, roller or airless spray at a rate of 6–8m²/litre. Apply 2 coats.

• If a fine non slip finish is required, it is possible to mix approximately 80# or finer aggregate into Epoxy Glaze 2 and roll for even distribution.
• If a coarser non slip finish is required then aggregate should be broadcast into the wet applied product and sealed with one or more subsequent coats.
