Preparations

Clean and dry surface.  Ensure surface to be coated is free of all dirt, grease, oil, paint, curing agents and other contaminants. Removal of Oil Contamination by degreaser and alkaline cleaning pressure wash

Acid-wash to enhanced surface porosity and etch the surface

Ensure moisture free surface.  Allow to completely dry, run Dry Test.  Place a piece of plastic over a small area, tape the edges and leave for 1 hour.  Remove plastic, if there is no moisture on either surface, concrete is sufficiently dry.

Ideally, always consider surface grinding and removal of loose materials.  Grinding is always advisable prior to application of all Shimicoat Epoxy products, to maximize adhesion.  For further information, please refer to SHIMICOAT Instruction for “Surface Preparations”

Epoxy vs Polyurethane

SHIMICOAT is the manufacturer and supplier of a wide range of Epoxy products for various applications and different desired performance results.  Epoxies have three most important desirable properties:

1.      Super strong bonding to a well-prepared concrete surface, creating a well-adhered system base that will allow subsequent build and topcoats. A complete coating system is only as good as its initial bond to the concrete substrate.

2.      High Build Up/ High Thickness epoxy application of 10mm or more, ideal for basecoat.  High Build Up/ High Thickness epoxy application of 10mm or more by self-levelling allows the coating to chemically bond to the epoxy primer, and is thick enough to your desire to self-level and fill minor concrete blemishes and hairline cracks. Depending on the desired performance requirements and condition of the concrete, more build coat applications may be installed by PourOn method. Upon curing, the epoxy build-coats provide a hard, durable surface.

3.      Easy Installation & High Performance upon curing, the epoxy build coats provide a hard, durable surface with good impact resistance

4.      Resilient, impact resistant, somewhat flexible and hard: Ideal for high traffic floor,

5.      Cost Effective when compared to many other industrial flooring solutions

The two major drawbacks with Epoxy products are:

a)      Sensitive to UV radiation of sunlight and they tend to amber or yellow over time, so non suitable for outside applications, under direct sun or UV radiation

b)     Epoxies are not as abrasion and chemical-resistant as polyurethanes, they are more susceptible to scratch and marks

SHIMICOAT recommend Epoxy applications for basecoat and those areas out of direct sunlight and Crystal Clear UVRes for all topcoat applications.

Direction

SHIMICOAT Polyurethane can be applied directly on surface or over other epoxy and decorative materials such as flakes or glitters.

Flake Flooring:

Ensure flaked floor has been uniformly scraped and all lose flakes vacuumed or removed from the surface.

Apply using a suitable roller or spread with a squeegee then level by back rolling.

One coat of SHIMICOAT Crystal Clear Polyurethane is enough for topcoat and two coats are ideal

The second coat must be applied within 24 hours of the 1st coat being applied, otherwise sanding may be necessary

 

Direct on Concrete:

Over new concrete, ensure concrete is sufficiently cured (recommended minimum 14 days), with moisture content of less than 5%. Skim grinding of the surface may be required to remove surface materials such as concrete sealer, paint, algae, mildew, mould, oil, grease and loosely bonded concrete.  If grinding is unavailable, we recommend acid wash followed by detergent wash and pressure cleaning.  Allow to thoroughly dry before coating.

Please refer to the following SHIMICOAT Procedures for further details:

1.      Surface Preparation Procedure

2.      Concrete Moisture Test

3.      Concrete Acid Wash

Application:

§  Calculate coverage rate of 5-7m² per litre depending on film build.

§  Pot Life of the product is 45 minutes depending on the temperature, get it out of the pol within 30min.

§  Blend enough that you can comfortably apply, not too much, not too little.  We recommend 2.5Lt (one person) or 5Lt Max for two people applying.

§  By weight or volume, Add 1 part of Part A into 4 parts of Part B.

§  Mix with slow RPM mixer or stick for 2-3 minutes gently and uniformly, in both directions.  DO NOT introduce air into the product, avoid aggressive mixing.

§  Use Neat.   Only if necessary, dilute by adding up to 5% AcryDil, EpoDil or Xylene into the mix to make it easier to roll out and apply to the surface.  Example of such situation is, during winter when temperature is closer to 10°C and resin is viscous or if you wish to thin it down during first application and allowing deeper penetration.

§  Mix well and commence application using brush, roller or squeegee.

Warning:

§  Do Not Apply if rain is expected within 24 hours, when applying outdoor

§  Surface Prep is crucial to ensure strong bonding.  Surfaces such as Porcelain Tiles, Polished or Burnished Concrete are not suitable for coating due to lack of surface porosity.

§  Sealed surfaces can become slippery when wet. 

§  DO NOT apply over existing Acrylic Sealers or other low-quality coating materials

§  Main three reasons detrimental to curing process of SHIMICOAT Crystal Clear UVRes Polyurethane:

o   Not mixed properly, mix for a minimum of 2 minutes using low speed electric mixer or paint mixer

o   Wet substrate with moisture content over 5%

o   Low atmospheric temperature, lower than 10 ℃

Warning:

UVthane is UV resistant sealer, NOT UV proof.  Avoid application under direct sun, for prolonged period of time, avoid applications to surfaces such as driveway and Swimming pool surrounding where fully exposed to sun radiation.

SHIMICOAT recommend Epoxy applications for basecoat and those areas out of direct sunlight and Crystal Clear UVRes for all topcoat applications.
