Hi-build Epoxy Floor Coating 

abe.®cote 400 Hi-build is an economical four-component, solvent-free epoxy flooring system comprising a clear resin and hardener, pre-packed filler and a ready-for-use pigment paste.

Uses

Floor coating in ablution blocks, walkways, food processing plants, hospitals and schools etc. May also be used as a binder for abrasive grit to yield non-slip floor finishes.

Surface Preparation

Precautionary Notes

(1) The substrate must be dry before application. For 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 m2 masked down on surface).

(2) Concrete substrate must have a minimum tensile strength of 1.5 N/mm.

Concrete shall be free of all laitance and preferably should be lightly vacuum blast cleaned leaving a uniform texture. All blemishes in the surface such as pop-outs, omegas, blowholes and honeycomb should be patched with epidermix 201. This should be left overnight to cure and shall then be rendered smooth. For a smooth final finish, the surface profile, peak to valley, should not exceed 25% of the coating thickness. If the surface is very irregular, consideration should be given to the use of abe.®prime SL, a solvent free epoxy self leveling primer.

Bonding / Priming

If abe.®prime SL is not used, then abe.®cote 400 Hi-build is normally applied over a thoroughly sealed concrete surface using up to two coats of abe.®cote 337.

Over coating of the primer with abe.®cote 400 Hi-build should comply with the over coating time requirements laid down for the specific primer. The over coating time for abe.®cote WD 337 is 4 – 6 hours.

Mixing

Precautionary Notes

(1) When decanting base from bulk supply, thorough stirring must be accomplished beforehand.

(2) In order to avoid colour variation in large expanses, one must ensure that the same pigment batch is used and is carefully and accurately dispensed (factory batching available on request).

Proper mixing and proportioning of the epoxy binder (base and activator), filler and pigment is essential for good results with no colour variation from mix to mix.

Transfer pre-measured volume of flooring base resin to mixer. Add pigment and activator and homogenize. Add filler slowly and mix well.

Note:

(1) 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. Also, for this type of mixing, transferring the base/activator combination to a new container i.e. “re-mixing” will eliminate contamination due to unmixed base which is inclined to cling to the walls of the original container.

(2) Where light colours (yellows/white etc.) are used, the addition of 2 units of pigment pastes per kit is advised to ensure opacity. A similar coloured primer is also recommended.

Coverage

Application

Precautionary Note

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

abe.®cote 400 Hi-build should be applied by first pouring a bead of material in the form of a ribbon on the surface to be coated. Do not leave material in the container too long because it will set faster thus reducing the work life. Using a serrated trowel, spread the applied material at the specified rate. Apply as evenly as is possible, working from left to right, and then back. Approximately 10 minutes after application, roll using a porcupine roller to aid in excess air release. All over-coating times must be strictly adhered to. abe.®cote 400 Hi-build will not cure if applied at below 10 ºC.

Non-Slip Surface

Precautionary Note

Overcoat times of 48 hours maximum must be adhered to at all stages.

A non-slip surface can be achieved by applying a clear bond coat of abe.®cote 400 Hi-build Resin onto the relevant cured pigmented abe.®cote 400 Hi-build System base coat at an approximate rate of 3 m²/L and broadcasting into this a suitable grit at the rate of approximately 50 g/m2. Ensure that grit application is evenly broadcast and back-rolled using a short mohair fibre roller.

Protection / Maintenance on Completion

Enlist the services of experienced cleaning specialists. Furthermore, the following recommendation will go a long way to maintain the original appearance of the epoxy floor viz.

(1) Protect from trafficked dirt/grit ingress into coated area by using dirt traps etc.

(2) Use of a “renewable” clear high wear polymer based floor polish will reduce scratching and “black heel”.

(3) Encourage frequent maintenance cleaning.
