- APPLICATION ADVICE:
1. Surface requirement & preparation:
➢ Suitable substrates are concrete or modified polymer screeds with a minimum compressive strength of 25 N/mm2 and pull-off strength of 1.5 N/mm2.
➢ Substrate to be coated must be clean, free from dust, oil, water, paint residues, loose constituents or any contaminants. Make use of a concrete surface planer, grit blasting, surface grinding or other mechanical means until a flat, rough profile is evident. Prepare grooves, 5mm(wide) x 5mm(deep), at all edges, bay joints columns, doorways, and drains for anchoring purpose.
2. Mixing:
➢ Shake the containers of components A and B before use. First put component A into a clean mixing vessel and stir in component D MC-DUR PowerCoat Color (pigment). Then stir in component B. Stir the liquid components with a slow-running stirrer for approx. 1 minute until a homogeneous, streak-free mixture is obtained.
➢ The aggregate (component C) is now added to the premixed resin components and mixed homogeneously. The use of a compulsory mixer is required for mixing the resin components with the aggregate. The mixing time depends on the pre-storage temperature of component C. At 18 – 22°C, a mixing time of 3 minutes must be observed.
3. Application:
➢ Apply MC-DUR PowerCoat 230 within its pot life.
➢ Spread the composite matrix to thickness of 3-6mm and consolidate with pin rake or notched squeegee set to the correct depth. Immediately release any trapped air by spike rolling.
4. Temperature:
➢ MC-DUR PowerCoat 230 should not be applied on material or floor temperatures below 10°C. Temperatures should not fall below 5°C in the first 24 hours after application. MC-DUR PowerCoat 230 is not designed for immersion.
➢ Service temperatures:
– At 3 mm : Resistance up to 80oC & for freezer temperatures -5oC
– At 6 mm : Resistance up to 90oC & for freezer temperatures -5oC
5. Curing:
| 25oC @ 75% RH | 35oC @ 75% RH | |
| Foot traffic. (hr) | 10 | 8 |
| Light traffic. (hr) | 24 | 18 |
| Full traffic. (hr) | 48 | 24 |
| Full cure. (days) | 7 | 5 |
6. Substrate movement: All moving joints must be carried through MC-DUR PowerCoat 230 and properly sealed. Construction joints and cracks may be covered but if substrate movement occurs, the MC-DUR PowerCoat 230 will reflect the cracks.
7. Chemical resistance:
MC-DUR PowerCoat 230 will resist spillages of :
➢ Dilute and concentrated acids: hydrochloric, nitric, phosphoric and sulphuric.
➢ Dilute and concentrated alkalis, including sodium hydroxide to 50% concentration.
➢ Most dilute and concentrated organic acids.
➢ Fats, oil and sugar.
➢ Mineral oils, kerosene, gasoline and brake fluids.
➢ Most organic solvents.
8. Cleaning:
Clean all tools with Washing Thinner or other solvents before the material hardens. Small unreacted Part B in container is to be decontaminated with a 5% solution of washing soda (sodium carbonate) prior to disposal. After material has set it is virtually impossible to get off and will only wear off over time.
9. Maintenance:
Regular cleaning and maintenance will prolong the life of all resin floors, enhance the appearance and reduce the tendency to retain dirt.
