PRODUCT INFORMATION

Aqua-Mite waterproofer™ provides a specially formulated two-component coating system that you can apply to almost any type of surface for waterproofing purposes.

This system comprises a unique blend of hi-tech powders in pack one and, in pack two, a very special fluid chemical blend. When you combine these components, they form an extremely potent surface coating capable of withstanding constant water presence.

Furthermore, Aqua-Mite waterproofer™ offers versatility as it can be used to repair specific leaks in a substrate or for general waterproofing and is safe for use with potable water. It is also a quick drying waterproofing coating.

Activation of the product involves a specially formulated compound. This not only provides waterproofing but also inhibits algae growth on its surface. This cutting-edge technology represents a groundbreaking advancement for underwater coatings.

Moreover, Cosmo-Dec, with its hi-tech approach to coating technology, consistently positions itself at the forefront of innovation.

In addition, our coating contains active ingredients that literally clean the water.

Surface preparation

The substrate onto which Aqua-Mite waterproofer™ is to be applied must be clean of loose dirt, dust, grease, grime, paint etc.

The substrate must also be dry.

In the event of cracks or splits or holes in the substrate, these are mended with a thicker mixture of Aqua-Mite waterproofer™ worked into the crack or hole with a spatula, and once dry (About 2 hours) they are over coated with Aqua-Mite waterproofer™ as a paint.

A membrane is also used in conjunction with Aqua-Mite waterproofer™ for obstinate repairs as well as the addition of plaster sand with the crack fill mixture for larger cracks or repairs.

Mixture

Mix one part of Aqua-Mite waterproofer™ powder with two parts of Aqua-Mite waterproofer™ liquid by volume in a suitable container. Stir for a couple of minutes or until all the powder is mixed with the liquid and there are no lumps.

Mix only enough to last for about a half an hour as the mixed Aqua-Mite waterproofer™ has a pot life of about one hour depending on weather conditions. Brushes and equipment can be washed with ordinary tap water, warm and soapy preferably, as the product is miscible in water.

Application & coverage

Apply the mixed Aqua-Mite waterproofer™ by brush, roller or spray applicator onto the suitably prepared surface. Do two coats 24 hours apart with brush strokes at right angles to one another per application.

Aqua-Mite waterproofer™ covers approx. 3 square meters per kg.

Instructions

Treating a hairline crack

Clean the substrate with a firm brush down to it’s original condition. At this time, Wipe away all loose dust and ensure the surface is dry. ( If hairline cracks are visible don’t do anything special to them.)

Mix sufficient powder and liquid together in a 5 Lt. container to do the area you are about to treat. Then, Add the powder to the liquid whilst stirring ensuring there are no lumps.

The mixing ratio for this coating is 2 Powders to one liquid by volume. Subsequently, An entire packet of powder and a whole bottle of liquid covers, in this way, about 22.5 square meters applying 2 coats. Use pro-rata measurements for smaller areas.

First work the mixture into the crack. Allow to dry (About 30 minutes on a sunny day).

Paint one coat of the mixture over the length of the crack about 50 mm wide.

Wait for about 30 minutes for that coat to dry before applying a second coat.

Note

Once mixed, the mixture has a limited pot life. So mix only enough to treat the specific task you are undertaking.

Treating a larger crack.

Open the crack in a “V” shape about 10 mm wide and 10 mm deep with a chisels edge or a screw driver.

Brush away loose dirt. Make sure the surface is clean and dry.

Mix 1 part of powder with one part of silica sand and about one quarter part of the white liquid plastic to make a paste.

Work the paste into the opened crack. Smooth over with the spatula. Allow to dry (About 30 minutes).

With sand paper, sand down the dried paste to provide a smooth surface flush with the surrounds.

Apply 2 coats of Aqua-Mite waterproofer™ paint mixture (2 powders to one liquid by volume) over the treated crack one at a time allowing drying time in between.

Waterproofer for dams and ponds

Treating a large crack where the substrate is weak.

Proceed as with the larger crack above up the point where you have smoothed over the dried paste with sand paper.

At this time, Cut a piece of membrane about 100 mm longer than the crack.

Mix the Aqua-Mite waterproofer™ paint mixture (2 powders to one liquid by volume) and paint a thick coating as wide and as long as the membrane you’ve just cut over the repaired crack.

Whilst the Aqua-Mite waterproofer™ paint is wet, stick the membrane over the repaired crack into place using the Aqua-Mite waterproofer™ as an adhesive.

At this time, Iron out all the folds and bubbles in the membrane. Paint 2 coats of Aqua-Mite waterproofer™ paint mixture over the entire membrane that has been stuck in place, allowing for drying time between coats.

Plastic tanks (Cracked)

Step 1.

Make or drill a small hole about 3 mm in diameter at each end of the crack to prevent the crack from running.

Roughen up the area to be treated with sand paper. About a 100 mm longer than the crack and as wide as the membrane. Brush away loose dirt.

At this time, Ensure the surface is clean and dry. Mix sufficient of the powder and the liquid together in a 5 Lt container to do the area you are about to treat.

Step 2.

Add the powder to the liquid whilst stirring, ensuring there are no lumps.

The mixing ratio for this coating is 2 Powders to one liquid by volume. Subsequently, An entire packet of powder and whole bottle of liquid can cover, in this way, about 5 square meters applying 2 coats. Use pro-rata measurements for smaller areas.

First work into the crack, with the paint brush provided, the mixture. Allow to dry (About 30 minutes on a sunny day).

Step 3.

Then, paint one coat of the mixture over the length of the crack about 50 mm wide.

Step 4.

Wait for about 30 minutes for that coat to dry. Apply a second coat over the first coat. Once mixed, the mixture has a limited pot life. So mix only enough to treat the specific task you are Undertaking.

Step 5.

Mix the Aqua-Mite waterproofer™ paint mixture (2 powders to one liquid by volume) and paint a thick coating as wide and as long as the membrane you’ve just cut over the primed crack.

At this time, Iron out all the folds and bubbles in the membrane. Paint 2 coats of Aqua-Mite paint mixture over the entire membrane that has been stuck in place, allowing for drying time between coats.

 Repair the crack on the INSIDE of the tank if possible.

Waterproofer for dams and ponds

Joints, seems, cracks, overlaps, holes or other specific leaks in any substrate

Proceed as with repairing a crack in a plastic tank except don’t drill any holes at each end of the crack. (If there is one)

As far as exterior surfaces are concerned work on the outside of the surface.

 The substrate must be clean and dry.

Three important rules to remember in coatings are preparation, preparation, preparation.

General waterproofing. (Metal, asbestos, tiles, concrete, plastic etc.)

Onto any surface that is porous or leaking, first clean the entire substrate and make sure it is dry before applying the first coat of Aqua-Mite waterproofer™ mixture (Two parts of powder to one part of liquid by volume.)

At this time, Coat the whole surface with brush or roller movements in one direction. Following this, apply a second coat of Aqua-Mite waterproofer™ after the first has had a chance to dry. Do this by applying with  the brush or roller at a 90 deg. angle to the first coat.

Don’t work if it is going to rain or if the surface is wet.

Dampen with water any concrete surface slightly before applying any mixed Aqua-Mite waterproofer™. Clean equipment with ordinary water.

MIXING WITH AQUA-MITE FLUID

The mixing procedure for mortars or concretes containing Aqua-Mite waterproofer™ Fluid closely resembles that used for conventional compositions. However, it involves partially or completely replacing gauging water with Aqua-Mite waterproofer™ Fluid.

The quantity of Aqua-Mite waterproofer™ Fluid recommended depends on the application and is normally from 9 to 18 litres per 50 kg of cement.

Typical examples of mortars are given in the appendix.

Portland, High Alumina and certain fast setting cements are compatible with Aqua-Mite Fluid and have been successfully used.

Water/cement ratio

Mortars containing Aqua-Mite waterproofer™ Fluid have a water/cement ratio lower than conventional mortars.

Aggregate

Many types of aggregate are successfully used in Aqua-Mite waterproofer™ Fluid modified compositions; typical examples are those conforming to the SABS 1090 – 1976 “Sand for plaster and mortar” as well as granite chippings used in heavy duty flooring.

Workability

The workability time is generally slightly increased by the addition of Aqua-Mite waterproofer™ Fluid. However, In cold weather conditions (below 10º C) especially when it is also damp, use a rapid or extra-rapid hardening cement.

Alternatively, ordinary Portland cement is used in conjunction with 2% – 4% of calcium chloride (expressed on cement weight); the calcium chloride added as a 50% solution in water to the mortar mix.

Additives

Workability additives such as fly ash and lime are not necessary as Aqua-Mite waterproofer™ Fluid exerts a considerable plasticizing effect of it’s own.

Air entraining agents must not be used without adequate testing. Also, The addition of an anti-foaming agent is sometimes desirable and we have found that Nopco NDW added at the level of 20g per 5 litres of Aqua-Mite fluid is an effective material.

Cleaning of equipment

All tools must be cleaned immediately after use, importantly, hardened Aqua-Mite waterproofer™ Fluid-modified cement compositions have excellent adhesion and are therefore difficult to remove.

If this important precaution is overlooked, solvents such as white spirit, solvent naphtha or preferably toluene can be useful in removing hardened Aqua-Mite waterproofer™ Fluid-modified mortar.

Note on anti-foam

For most applications, addition of anti-foam is not normally necessary when using Aqua-Mite waterproofer™ Fluid. However, occasionally, it may be desirable to incorporate an anti-foam in some Aqua-Mite waterproofer™ Fluid-modified flooring compositions, eg those containing flint aggregates.

If anti-foam is required, we recommend the addition of Nopco NDW added at the level of 14 g antifoam per 5 litres.

WALL RENDERINGS

Preparation

The wall surface must be free from crumbly or other unsound debris. In addition, dusty patches and old paint must also be removed. However, it is sufficient to prepare the wall with a wire brush.

Dampen all surfaces an hour or so before priming.

Priming

We recommend a priming coat to obtain maximum adhesion of the subsequently applied rendering. This priming coat, consisting of 2 parts of ordinary Portland cement slurried with 1 part of Aqua-Mite waterproofer™ Fluid, should be thoroughly brushed on to the prepared wall surface, equally important, rendering is applied whilst the mixture is still wet.

Mixing

A general purpose rendering compositions is as follows:

• SABS 1090 – 1976 “plaster sand” 100 kg.

ordinary Portland cement * 33 kg.

Aqua-Mite Fluid 6 litres.

water as required to adjust consistency.

See earlier remarks with regards to using rapid hardening cements or calcium chloride in cold weather conditions.

We highly recommend using a concrete mixer, although hand mixing is permissible where the total weight of the dry batch does not exceed 50 kg.

Furthermore, the usual procedure is to quickly pre-mix the sand and cement in a mixer, pour in the Aqua-Mite waterproofer™ Fluid, mix for 2-3 minutes and finally cautiously add water little by little until the required consistency is achieved. Over addition of water causes rapid thinning of Aqua-Mite waterproofer™ Fluid modified mortars owing to the plasticizing effect of the Aqua-Mite waterproofer™ Fluid.

Application

Several coats applied in rapid succession is sufficient to allow each coat time to set-off to receive the next coat. Time required between coats varies according to conditions but is typically 15 – 30 minutes.

Waterproofer for dams and ponds

WATER RESISTANT RENDERING

In cases where improved water resistance is the primary requirement for rendering, we recommend a modified application technique.

After you’ve prepared the substrate as described earlier, it’s time to apply two sealing coats. These consist of approximately two parts of Portland cement slurried with one part of Aqua-Mite waterproofer™ Fluid. In addition, ensure that you thoroughly brush these coats onto the surface.

The second sealing coat can be applied as soon as the first coat is touch dry, usually around 20 to 30 minutes. Ideally, apply the sealing coats at right angles to each other to guarantee complete coverage of the substrate.

Furthermore, it’s essential to note that the thickness of each sealing coat should not exceed 1,6mm to prevent cracking. Before proceeding further, allow the double sealing coat system to dry out completely for at least 48 hours.

The amount of Aqua-Mite waterproofer™ Fluid required in the rendering composition depends upon the degree of water resistance required and the conditions prevailing during application. However, the addition of 14 litres of Aqua-Mite waterproofer™ Fluid per 50 kg of cement is usually satisfactory.

We recommend a level of 20 litres of Aqua-Mite waterproofer™ Fluid per 50KG cement where high hydro static pressure is anticipated

Because the application of water-resistance rendering is a specialized procedure, we advise that each customer to consult us for recommendations appropriate to their individual requirements.

FLOOR SCREEDS

Preparation

Where the existing floor is old or dirty, remove all contaminants such as oil, grease as well as paint to ensure adequate development of bond when the topping is applied. Furthermore, remove any unsound crumbly concrete.

An efficient way of preparing an old floor is to use a mechanical scabbler to remove all unsound materials. If the concrete is in reasonably good order light scabbling will suffice, eg, to a depth of about 2 – 4 mm.

 Remove the upper surface to ensure that weak surface latency is not present. In general, light scabbling to a depth of up to 4mm will normally suffice.

Alternatively, good results obtained by etching either new or old concrete floors with hydrochloric acid (1 part of concentrated acid diluted with 2 parts of water) followed by a thorough washing to remove all traces of acid.

Additionally, if screed bars are to be used to define thickness of the screed, these must be positioned after the above preparation.

Priming

We recommend a priming coat to obtain maximum adhesion of the subsequently applied screed. Dampen the prepared floors thoroughly with water, then remove excess standing water before application.

  Then, thoroughly brush a priming coat, consisting of 2 parts of ordinary Portland cement slurried with 1 part of Aqua-Mite waterproofer™ FLUID into the floor using a stiff broom.

The topping is applied whilst the priming coat is still wet.

For general-purpose topping, the following composition is recommended :

SABS 1090 – 1976 “mortar sand” 100 kg.

Ordinary Portland cement 33 kg.

Aqua-Mite waterproofer™ Fluid 6 litres.

Water as required to adjust consistency.

The mixing procedure is straight forward, and is also as described in the section dealing with wall renderings.

Application of topping

Aqua-Mite waterproofer™ Fluid allows “feather-edging” of suitable mortar compositions, it can patch up only the damaged portions of existing concrete floor. These portions must also be prepared and primed as previously described.

As an alternative procedure, carry out further troweling after a suitable interval, when initial stiffening of the mortar has commenced. In particular, we recommend a clean steel trowel is for this operation.

Timing

Too great a time interval on the other hand would result in the mortar having set too much to be smoothed. In addition, the whole surface should be troweled, not just sections of it to avoid variations in shade, texture, etc.

Heavy duty flooring

 The procedures for preparing and priming the existing floor and for mixing and application is also as described for general purpose floor screeds.

However, Iron aggregate flooring is the exception to this. Therefore, we recommended laying as a 6 mm topping.

A typical heavy-duty composition is as follows:

Portland cement 100 kg.

SABS 1090 – 1976 “mortar sand” 125 kg.

3mm granite chippings 125 kg.

Aqua-Mite waterproofer™ Fluid 18 litres.

Water as required to adjust consistency.
