abescreed flooring for a seamless flooring system

• Seamless and hygienic finish when sealed, no crevices where dirt and bacteria can gather
• Excellent chemical resistance to sugars and acids
• Clean and sterile, low maintenance requirement
• Non-slip finish
• High abrasion resistance
• Solvent-free; low odor
• Far longer life than unprotected concrete floor
• Excellent resistance to damaging liquids

PRECAUTIONARY NOTES

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 (approx. 1m² masked down on surface).

Concrete substrate must have a minimum tensile strength of 1.5N/mm².

Concrete shall be free of all laitance and preferably should be lightly vacuum blast cleaned leaving a uniform texture. All surface defects may be patched with abescreed – see under application below.

Prior to application of abescreed, apply a tack coat of neat flooring resin. The abescreed is trowelled directly into this wet coat within 30 minutes of priming. Should the application of the screed be delayed, the tack coat should be blinded with abecoarse silica sand while still tacky and allowed to cure. All excess and unbonded aggregate must be vacuumed away. This will provide a mechanical key suitable for bonding. Apply abescreed within 48 hours.

The resin and hardener must be pre-mixed prior to use. Colour Additives: If colour is desired, the appropriate pigment paste is added to the Base at the specified rate.

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

In order to avoid colour variation in large expanses, one must ensure that the same batch product component is used and is carefully and accurately dispensed (factory colour 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:

A slow speed mixer must be used. Ensure that the mixing vanes are below the surface of the mix (liquid components) to minimize air entrapment. The stirrer mixing vane configuration should be such as not to introduce unwanted aeration. The blended liquids are then thoroughly mixed with the “special” graded aggregate using a rotating pan type mortar mixer.

PRECAUTIONARY NOTE

Prevailing weather conditions must be taken into account otherwise surface defects can occur (see under “properties of wet material”). abescreed epoxy mortar mixture is immediately used to fill in any holes, cracks and crevices using a margin trowel. The material is then spread with a gauge rake, trowel or screed box, to the desired thickness.

Finally the material is evenly compressed using a plastic finishing trowel, finish moving the trowel from left to right. The finished surface should be relatively smooth, free of trowel marks and without open areas. abescreed can be used for making turn-ups on walls, columns and other surfaces to a height of 150 mm. Careful application should ensure that the trowelled floor is non-porous and will not require an additional sealer coat. However, if severe chemical spillage is encountered and doubt exists regarding the non-porosity of the flooring, a sealer coat should be applied over the cured floor.
abescreed should be sealed with abecote 436 clear epoxy sealer coat. It must be appreciated that sealing of abescreed compromises its natural non-slip finish, but abrasive fillers may be incorporated into these sealer coats to restore and in some cases improve non-slip properties. They are applied at a rate of about 15-30 g/m². See ‘Nonslip Abrasives’ literature. All over-coating times must be strictly adhered to. abescreed will not cure if applied at below 10 °C.

abe® super brush cleaner before setting.

Protect surface against traffic and spillage until cured. Most epoxies chalk and degrade in extensive sunlight.

The flooring system will be abescreed, a four-component, solvent-free, epoxy comprising a clear resin and activator blended with a pre-packed graded aggregate and a colour pigment applied in accordance with a.b.e.®’ recommendations, including abe.®cote 436 sealer as directed.

All abescreed related products have a shelf life of 2 years if kept in a dry, cool store in the original, unopened packs. If stored at high temperatures and/or high humidity conditions, the shelf life may be reduced.
