Safe Use of This Product

Safe use of this product requires good work practices. MSD Sheets

are available on request. Please familiarise yourself with these

sheets before starting work. The solvent levels in SwiftEpoxy HB

are low, but vapours will still be present as the paint is applied and

the paint film cures.

Be aware of this and plan your work

accordingly. The hardener is a corrosive and care should be taken

when handling. Contact with skin or eyes is to be avoided.

SwiftEpoxy HB

Preparation and Application

for Swimming Pools

Surface Preparation

Important Note: The purpose of surface preparation, for this

coating or any other, is to produce a surface that is clean and

sound. Anything other than a clean and structurally sound

surface will detract from the life span of any coating applied

to it.

This reduction in life span will be even more

pronounced in immersion conditions.

All substrates must be sound, free from grease, oil and fats,

and free of soluble salts. If you are aware of serious

contamination of your substrate, contact a professional to

prepare the surface for you, or contact Macleod Industries

directly for more information.

Basic Techniques used in Preparing Surfaces

Degrease and Rinse

Degrease surfaces using a solution of EC101 (preferred) or other

degreaser at concentration specified on package. Manually scrub

using a stiff bristled broom or scrubbing brush and rinse thoroughly

when finished to remove all grease, fats, and oils. Ensure all

residues are thoroughly removed; rinse with clean potable water

with low dissolved mineral content. If substrate is a swimming pool

or spa, pay particular attention to the waterline and above, and to

the shallow areas and the steps.

Waterblast

Water-blast at 3000 p.s.i. or higher. Tip should be no further than

80 cm from the surface to ensure good pressure. This removes

solubles and unsound paint or substrate. If removal of unsound

paint is required, it is recommended that the surface be water-

blasted a second time, at least one hour after the first blasting. The

water used should be low in dissolved minerals.

Acid Etch and Rinse

Read all safety instructions on the container of acid before

beginning. Protective mask and clothing should be worn. Rinse

with a solution of spirits of salts (

33%

-

35%

hydrochloric acid) to

react and solubilize alkaline salts and remove them, and to etch

smooth surfaces. Spirits of salts should be diluted

1:3

(acid: water).

A plastic watering-can equipped with a rose is recommended for

mixing and application of acid. Always add acid to water. Ensure

that every part of the surface is exposed to fresh, unreacted acid.

Rinse immediately with water free of soluble minerals; acid

residues must not be allowed to dry on the surface.

Abrasion

Abrasion is necessary to reduce the gloss of a previous epoxy or

urethane coating, or where loose rust on a metal surface is present.

Sandblasting, wet sandblasting, disc grinding with angle grinder, or

manual abrasion with grit paper are all acceptable. Metal surfaces

should be abraded to SA

2.5

. Remove grit and paint and substrate

particles from area when finished.

Preparing Mineral Substrates for

Painting

Mineral substrates include:

● Concrete and concrete form-work

● Cement render

● Cement sheeting and cement and terracotta tiles (unglazed).

● Marblesheen

™

,Quartzon

™

,and other coloured renders, not

including pebbled render surfaces

● Note: Render or render patches which have been modified with

resins may be difficult to overcoat. If your render has been

modified with resin, please contact Macleod Industries or the

render manufacturer before proceeding.

Preparing New Mineral Substrate

● Make sure that the substrate has cured fully

● Acid Etch and Rinse. Ensure that the substrate is now rough.

Steel-troweled finishes can be quite smooth, and may require a

second acid etch and rinse

Preparing Aged Unpainted Mineral Substrate

● Degrease and Rinse

● Acid Etch and Rinse

● Water-blast

Preparing a Mineral Substrate Previously Painted with a 2-Part

Epoxy, or 2-Part or Moisture-Cure Urethane

● Degrease and Rinse

● Acid Etch and Rinse

● Allow to dry. Examine gloss level of paint and abrade any areas

where gloss remains. If previous coat is SwiftEpoxy HB, no

abrasion should be necessary

● Water-blast, wait an hour. If paint is curling at edges, water-blast

again. Repeat, if necessary. If this continues, you may need to

sandblast to remove all paint.

Preparing a Mineral Substrate Previously Painted with

SwiftVulc or other Chlorinated Rubber

● Not recommended. SwiftVulc is a more appropriate product for

this application.

Preparing Mineral Substrates with another type of Coating

● Contact Macleod Industries directly for advice specific to your

application.

After Surface Preparation of Mineral Substrates

SwiftEpoxy HB is not a patching compound, although it does

have some crack-filling characteristics. If blowholes or cracks

are present, they should be patched after cleaning and before

painting. Straight render should be allowed to cure fully, and be

acid etched before painting.

2

-component epoxy patching

compounds should be abraded to remove all gloss after curing.

Please ensure the patching compound you are using is

recommended by the manufacturer for your application.

SwiftEpoxy HB is not a membrane, and will not solve serious

engineering problems.

SwiftEpoxy HB

Preparation and Application

for Swimming Pools

Preparing Steel for Painting

●Degrease if any grease or oils are present. Dry surface as quickly

as possible after rinsing.

●Abrade to remove loose rust or mill scale if present. Mill scale

cannot be removed by hand sanding.

●Treat surface with a wash on/wash off rust converter.

Preparing Aluminium for Painting

●Degrease and rinse if any grease or oils are present. Dry surface

as quickly as possible after rinsing

●Lightly abrade to remove white rust, if present, and to roughen the

surface to promote adhesion

Preparing Fibreglass

●The variables with fibreglass are too numerous to detail in this

publication. Contact Macleod Industries directly for additional

information

Preparing Other Substrates

For technical advice on your specific application, contact Macleod

Industries directly.

After Preparation

Substrates must dry after surface preparation before painting begins.

Coating substrate with standing water or extreme wetness will lead

to adhesion loss. Rising damp is an engineering issue, and will not

be solved by a coating.

Application Technique

●Roller: Use a 10 mm nap, quality synthetic (Rolana or

equivalent) or lambs wool roller.

●Brush: Use any solvent-resistant (epoxy set) brush.

●Cleanup: Thin and clean-up only with SVX Thinner, as directed

for your application. Thin only as instructed. Any spills of part A

or B should be wiped up with SVX and disposed of safely.

●Mixing/Stirring: Part A should be well-stirred before Part B is

added. There should be two distinct layers to Part B. Do not

attempt to mix part packs. The two layers of Part B mix with

each other only in the presence of the resin in Part A. Add part B

to part A while stirring. Stir together thoroughly to achieve a

uniform mixture, so that there are no streaks All paint should be

well stirred to a uniform consistency before and during use. Use

a broad paddle or mechanical stirrer. Do not use a stick or dowel.

Induction: After mixing, allow to stand for 10 minutes before

stirring again, then applying.

●Mixed Pot Life: SwiftEpoxy HB has a mixed pot life of

approximately 90 minutes at 20

o

C and 50% relative humidity. Do

not attempt to extend this time by thinning with SVX, as chemical

properties will be adversely affected.

Application Conditions

Temperature: At the substrate, temperature should be between

5º

and

25º C

. Painting of mineral substrates is best done to avoid the

peak temperature of the day, as the substrate temperature is static or

falling.

Humidity: Any humidity level is acceptable, assuming a the

substrate is not wet from rain or condensation (dew).

Intercoat Times: Minimum 12 hrs, maximum 30 hrs at

20º C

and

50%

relative humidity. You must prepare the surface again if the

previous coat can no longer be indented with a fingernail. Best

practice is for two coats to be applied starting at the same time on

subsequent days.

Spread Rate: Recommended spread rate is 8 m

2

/ltr per coat, to

produce a dry film build on a non-porous substrate of

approximately 110 microns per coat. Attempting to apply the paint

at greater than the recommended spread rate will result in a grainy

finished film with poor protective qualities. The paint may be

applied as a high-build coating at up to 160 microns on walls,

higher on floors (about 6 – 7 sq metres per litre).

Cure Rate: SwiftEpoxy HB is touch dry within 6 hrs, print free

within 10 hrs at conditions of

20º

C and

50%

RH, assuming good

airflow. Solvent release from coating is not possible once the

coating is immersed in water. Allow a minimum of 5 days before

immersing. Do not expose to strong chemicals until 12 days after

painting.

Painting Mineral Substrates

● You will need to prime unpainted mineral substrate with one coat

minimum of SwiftEpoxy primer or other primer as recommended

by Macleod Industries. Marblesheen

™

, Quartzon

™

, or other

coloured or very porous substrates may require two coats.

● After priming/sealing, or over previously existing paint, apply

two coats of unthinned SwiftEpoxy HB at standard spread rate.

Painting Steel

● Prime with a suitable metal primer (zinc rich or etch primer)

which can be overcoated with epoxy paints.

● Apply two coats of SwiftEpoxy HB, unthinned.

Painting Aluminium

● Contact Macleod Industries directly for application advice.

Painting Fibreglass

● Apply two coats of SwiftEpoxy HB, unthinned.

Painting Other Substrates

● Contact Macleod Industries directly for application advice.

Product Data

SwiftEpoxy HB

Preparation and Application

for Swimming Pools

Important Notes:

●Check batch numbers on part A. If tins of part A are from

different batches, and there are not enough of any one batch for a

single coat, mix the different batches together before application.

●This product is an epoxy, and as such is prone to the effects of

UV light. In all bisphenol-based epoxies this takes the form of

yellowing and chalking. SwiftEpoxy HB has been engineered to

minimize this occurrence, but chalking will still occur over the life

of the coating. Chalking and yellowing will be most extreme

under harsh chemical environments, and in full sun.

●SwiftEpoxy HB is not a flexible coating. If substantial substrate

movement is expected, another coating type may be more suitable.

●Many coloured render swimming pool finishes were never

intended to be painted. As adhesion of paint was not engineered

for, overcoating is sometimes difficult. Coloured or uncoloured

render surfaces with no topcoat may degrade to the point of being

unsound in fully immersed conditions. Painting will not solve

serious structural problems.

●Allow film to cure before immersing in water. For swimming

pools, the standard is 5-7 days. It is vital that the small amount of

solvent in SwiftEpoxy HB leaves the coating before fully

immersed. Chemical curing takes place even after the solvent is

gone, and even under full immersion. It is recommended that you

do not chemically treat your pool for 2 days after filling, and do

not superchlorinate, or “shock” the pool, at least for the first two

weeks of operation. Macleod Industries Australia advises that

avoiding “shocking” the pool will greatly enhance the lifespan of

its own product or of any pool finish.

●Macleod Industries is not associated with the manufacturers or

installers of Marblesheen

™

or Quartzon

™

. Macleod Industries

neither promotes nor disparages these products, and the names of

these products are merely used as an example of coloured render

finishes in common use in Australia.

●Ensure that water you use to fill fish ponds or water features

which will contain fish is suitable for the purpose. A large

percentage of council and bore water contains chlorine and

fluorine compounds, or other minerals, at levels which are

injurious to certain aquatic animal and plant life. Contact pet and

plant shops in your area which specialize in fish and aquatic

plants for advise on treating the water in your area.

●Follow the advice of a qualified pool maintenance professional on

proper chemical levels for your pool.

The Langelier Index is the Best Buide You Can Use

to Determine Whether Your Pool is Balanced.

Safe Use and Handling:

●Avoid contact with skin and eyes. Avoid breathing vapour.

●Wear protective gloves and clothing when using SwiftEpoxy HB

●If poisoning occurs, contact a doctor or the Poisons Information

Centre in your area.

●If swallowed, do not induce vomiting. Give a glass of citrus juice

or water.

●If skin contact occurs, remove contaminated clothing and wash

skin thoroughly.

●If in eyes, hold eyes open and flood with water for a minimum of

15 minutes and contact a doctor.

Environmental Protection:

●Do not spill this product or its thinner in or near waterways.

●Spilled paint (fully mixed A and B), drop cloths with paint spills,

used rollers and soiled clothing may be safely disposed of as

household rubbish only when the paint is fully cured and

entirely free of all solvent.

●Residuals in part B are a corrosive and should be disposed of

safely. Part A tin is inert chemically if you have mixed parts A

and B in that tin and after any residual solvent is gone. The fully

cured Part A tin may be disposed of safely with Hard & Green

rubbish pick ups. Contact your council or rubbish collection

company. You may return any and all packaging of these

products to Macleod Industries for disposal. Any drips of Part B

should be wiped up with a rag wet with SVX thinner. Rags,

clothing or other items wet with unreacted Part B, or the container

Part B is shipped in, should never be disposed of with household

rubbish. Please return to Macleod Industries or contact

professionals for advice.

●Please contact Macleod Industries directly if you or your

organization have questions or advice about the environmental

impact of Macleod products.
