Application of abe.®cote tough PU paint incorporated coloured decorative flakes

All the relevant product data sheets and MSDS’s are to be read for additional information i.e. pot life, mixing instructions, surface preparation, ventilation, temperature and application limitations, etc.

Surface Preparation

Surfaces must be clean, mechanically sound, free of laitance, nibs, dust, grease and oil. The concrete surface should be prepared by means of vacuum assisted grinding, or other approved method of preparation leaving an open uniform fine textured surface.

It is advisable to check bonding on unfamiliar surfaces. Older coatings must be sanded.

Precautionary Notes
  1. The substrate must be dry before application. Concrete moisture content tests must be conducted prior to application of the priming system. Maximum moisture content should be between 4-5%. (preferably a Protimeter Survey Master or equivalent, or Dynamic Calcium Chloride moisture “weight gain” over 24 hours, or at least a practical overnight “plastic sheet test” is also advisable (approximately 1 m. edges masked down onto the concrete surface).
  2. All blemishes in the surface such as pop-outs, omegas, blowholes and honeycombing should be patched with epidermix 201. This should be left overnight to cure and shall then be rendered smooth.
  3. Concrete substrate must have a minimum tensile strength of 1.5 N/mm2.
  4. For a smooth final finish, the surface profile, peak to valley, should not exceed 25% of the coating thickness.
Bonding/Priming

Apply 10% diluted abe.®cote tough polyurethane paint as a prime coat.

Mixing

Precautionary Note:

When decanting product from bulk supply, thorough stirring must be accomplished beforehand.

Thoroughly mix the abe®cote tough polyurethane paint prior to application. At this point for the primer coat add 10% potable water and mix thoroughly.

To ensure good mixing, mechanical mixing equipment should be used (below 400 r.p.m) to avoid air entrainment (Jiffy type stirrer is ideal). Transfer the mixed product to a paint tray and apply. Left over product in containers must be carefully sealed to prevent the product from drying out and not subjected to possible contamination.

Application

Precautionary Note

Prevailing weather conditions must be taken into account otherwise surface defects can occur (see under “properties during application”).

NOTE: A slow speed mixer must be used. Ensure that the mixing vanes are below the surface of the mix to minimize air entrapment. The stirrer mixing vane configuration should be such as not to introduce unwanted aeration.

abe.®cote tough polyurethane paint will not cure if applied below 10°C.

System Process
  1. Prime the prepared surface with abe.®cote tough polyurethane paint (diluted with 10% potable water) by first pouring a bead of material in the form of a ribbon on to the surface followed by brushing or rolling with a virgin mohair roller to obtain the required coverage rate (approximately 3.5 m2/litre), and allow to dry approximately 4 hours depending on the temperature and humidity conditions.
  2. Apply the second coat (undiluted) of abe.®cote tough polyurethane paint at approximately 7.5 m2/litre and allow to dry for 4 hours as in point 1 above.
  3. Apply the third coat of (undiluted) of abe.®cote tough polyurethane paint at a coverage rate of approximately 7.5 m2/litre and then immediately broadcast/scatter the flakes evenly into the still wet abe.®cote tough polyurethane paint and allow the system to cure overnight.
  4. Remove the excess fl akes by brushing or vacuuming followed by a light sweep with a steel float or light sanding to remove any high spots followed by brushing or vacuuming the loose particles to result in a clean dust free surface.
  5. The final two top coats of abe.®cote tough polyurethane paint clear (gloss finish) or abe.®cote PUD clear (matt finish– see respective data sheet for additional information) to be applied at coverage rates of approximately 8 and 10 m2/litre respectively per coat.

Coverage rates offered may vary due to substrate surface profile changes and absorption properties.

Typical coverage rates for flakes are: Sparce scatter: 30 to 80 grams/m2.  Personal requirement: between 80 to 400 g/m2. Saturation level: up to 400 grams/m2.

Cleaning of Equipment

Tools, brushes and mixing equipment use water immediately after use or abe® super brush cleaner before full drying takes place. Hardened material can only be removed by mechanical means.

 

Protection/Maintenance on Completion

Protect the surface against traffic and spillage until cured.The use of abe® super brush cleaner will remove any uncured material from the tools.

Handling & Storage

At least 12 months in original, unopened containers. Store in cool (+5 °C up to + 20 °C) and dry conditions. Not frost resistant. If stored at high temperatures and/or high humidity conditions, the shelf life may be reduced.

Health & Safety

Product safety information required for safe use is not included. Before handling, read product and safety data sheets and container labels for safe use, physical and health hazard information. The safety data sheet is available from your local a.b.e.® Construction Chemicals sales representative.
