Aquepoxy® will not peel or flake, is hard wearing, solvent free and has very low odour making it suitable for application in most industrial and trafficable floors, food process and occupationally sensitive areas.

Aquepoxy® is the most cost effective way to provide a safe, low maintenance workplace or public area whilst adding prestige and value to your investment.

Aquepoxy® Concrete Floor Sealer was designed for direct application to stable substrates such as concrete, masonry and brickwork. It also performs well on flooring grade particle board and plywood but is not suitable for application to polished surfaces or natural timber floors.

Aquepoxy® is a medium build coating system designed for application to relatively smooth surfaces / concrete floor finishes. Aquepoxy® is ideally suited to most factory, warehouse and workshop situations. Gives a consistent and attractive finish with excellent wear characteristics on a relatively smooth surface but does not level or repair rough and inconsistent floors. Aquepoxy® should not be confused with a self-leveling seamless epoxy concrete floor finish that falls into a much higher applied price bracket of $40-50 per sq./mt. and can be used to repair rough and uneven surfaces.

All epoxy concrete coatings chalk slowly when exposed to sunlight. Aquepoxy® sealers are formulated to minimize this degradation and will generally give better adhesion to exterior concrete than other systems. As a general rule, lighter colours can be used but we would not recommend Aquepoxy® Clear finish or darker colours for exterior use.

Fresh concrete epoxy paint finishes can usually be coated after 14 days, depending on curing conditions. Allow a further 2 weeks if the floor has been curing at low temperature. No acid etching or other preparatory steps are needed, other than hosing off efflorescence and construction debris, then vacuum to remove surface dust and debris from sawcuts etc.

Aquepoxy® is a water-based system and can be applied to a damp concrete surface, unlike solvent based and seamless and self-leveling finishes. Vacuum any ponded water, then Aquepoxy® can be applied to the damp concrete epoxy paint surface.

Old concrete epoxy paint floors can often present adhesion problems for any coating or adhesive. Many coating systems do not adhere well to this highly alkaline surface. The top layer of aged concrete will gradually degenerate to an unsound powdery, dust-like surface, to which adhesion can be a problem. Soluble salts (efflorescence) often migrate to the surface, further hindering adhesion. Aquepoxy® sealers are extremely forgiving when applied to degraded concrete floor finish surfaces with excellent penetrating , binding and adhesion qualities and usually performs well even when applied to a low quality concrete surface.

Aquepoxy® will not fix powdery, crumbling or otherwise defective floors but will usually perform well when other concrete floor coatings fail. When in doubt, an adhesion test should always be carried out prior to application of Aquepoxy®. Diamond grinding may be required if adhesion is suspect.

It is a common misconception that acid etching will remove existing coatings, oil and grease. This is not the case. Acid etching is designed to remove laitance (a weak, poorly-cured layer on a concrete surface as a consequence of excessive bleed water, often from over-trowelling). Acid etching can cause more problems than it solves if not carried out strictly in accordance with correct procedures and is generally not necessary, nor recommended, before the application of Aquepoxy®.

Aquepoxy® is relatively tolerant of contamination from oily materials. In areas of heavy grease, we recommend the use of a strong, hot detergent wash and high pressure clean. Follow up with clean, fresh water to remove all traces of detergent. Vacuum any ponded water then Aquepoxy® can be applied even when the surface is damp.

There are three common classes of concrete curing membranes: PVA, chlorinated rubber and wax emulsions. PVA latex polymers, although the least effective as curing membranes, do not usually need to be removed before Aquepoxy® is applied. Wax-based curing agents and chlorinated rubber-based systems in particular, must be removed before application of Aquepoxy® or indeed any surface coating or flooring adhesive.

As a general rule, if the sealer or coating is wearing away and there is no evidence of peeling or flaking, it is usually safe to apply Aquepoxy®. However, some floor sealers (E.G. Polyurethane) and concrete curing membranes (see above) cannot be successfully recoated. You should always apply a small test patch of Aquepoxy® to any previously painted or suspect surface and check the adhesion after 48 hours before proceeding on a commercial scale.

Adhesion can be tested by cross-hatching the surface with a sharp blade, applying a strong adhesive tape, and then removing the tape in a single, rapid motion. Traces of the coating on the tape will confirm relatively poor adhesion. Bear in mind that the overall adhesion will only be as good as the “weakest link” between coatings, or between coatings and the substrate.

A previously-applied coating showing any sign of peeling or flaking must be completely removed, usually by diamond grinding or similar treatment to provide a sound concrete base. Similarly, if your adhesion test fails, all traces of the previous coating must be removed and adhesion rechecked before application of Aquepoxy®.

For two coat application (normal specification), one 25lt kit of Aquepoxy® will give coverage of 100-120 mt2 depending on the porosity of the surface.

For three coat application i.e. for R11/R12 slip requirement and high traffic areas such as toll booths / turning points in basement car parks or for extended warranty, one 25lt kit of Aquepoxy® will give coverage of approximately 70-80 mt2.

Dilution is not usually recommended for roller application to ensure that the necessary film build is achieved. In some rare situations – and only when specifically recommended by CavcoProducts or its distributors, Aquepoxy® may be diluted for the remediation of very highly porous areas in epoxy concrete coatings.

The second coat can usually be applied as soon as the surface is dry enough to walk on, usually about four to six hours after the first coat is applied depending on drying conditions.

These problems are usually caused by variation in texture (roughness) and/or porosity of the concrete floor finish. The first coat of Aquepoxy® seals the porous surface and allows the second coat to dry with minimal sheen variation. Some variation should be expected on particularly rough surfaces and additional coats will give improved uniformity.

Lap marks can occur when wet and dry layers are overlapped during application, resulting in visible areas of thicker film build. This is a common problem with clear and semi-transparent finishes when applied over large surface areas. Where possible, try to ensure that the edge of the applied coating does not dry before lapping-in with a layer of fresh coating. Aquepoxy® Sealer/finishes are formulated with long wet edge/open time properties to minimize this effect. Good application practice should always be followed to avoid lapping problems, for example by making use of saw cuts or expansion joints to break down a large floor area into smaller manageable sections.

Aquepoxy® Sealers are water based and exhibit very low odour, consequently ventilation is often ignored. It is important that water is allowed to evaporate and escape before curing of the epoxy binder occurs. Applicators should encourage air flow across the floor to avoid pockets of moisture vapour settling on the floor and suppressing evaporation. Open doors and use a fan to assist air flow across the floor, especially for application in small or confined areas. Try to avoid application of Aquepoxy® when humidity is high.

Aquepoxy® sealers are formulated to give a low sheen finish. A gloss finish can be achieved by application of an additional coat of Aquepoxy® Clear Gloss but this will downgrade slip resistance (especially when the floor is wet) and is not usually recommended or encouraged.

Aquepoxy® has been applied to concrete, masonry and brick vertical surfaces with very good results. However, Aquepoxy® sealers are primarily formulated for high-build application and controlled flow on horizontal surfaces (such as an epoxy garage floor), so minimizing the effects of substrate variability. For application on walls and other vertical surfaces, Aquepoxy® should be applied at 14-16 mt2/litre to avoid sagging. Line White, Off White and pastel colours are not recommended for application on vertical surfaces.

Aquepoxy® is a hard wearing, two-pack epoxy coating. Epoxy concrete coatings are recognised as being amongst the toughest and most abrasion resistant coatings available. Any concrete floor coating will eventually wear through via abrasion. The three factors determining how long the epoxy concrete coating will last are the coating film thickness, the degree of abrasion the coating is subjected to and of course, the quality of the coating.

When applied over sound concrete and subject to light foot traffic, Aquepoxy® would be expected to last many years, even 10 years or more in light traffic areas. The lifetime of the coating will be reduced in areas of highly abrasive, frequent traffic such as on an epoxy garage floor, toll gates, forklift doorways etc. and may require periodic recoating in these areas.

Generally two hours @ 25oC - shorter if ambient temperature is above 25oC. A 25Lt mix of Aquepoxy can usually be applied well within a two hour period of continuous application. However, mixed Aquepoxy should always be discarded if more than two hours old. Ie: if application has been interrupted for any reason.

Aquepoxy needs to be stored as separate components in a cool place and has a shelf life of 12 months. The Aquepoxy7 latex component (Part B) may crystallise (freeze) if stored at low temperatures for extended periods. Should this occur please contact your supplier for instructions.
