Description and Application
Epoxy Based Primer
EpoxiPrime has been specially formulated to achieve adhesion of subsequent coats to difficult surfaces like glass, tiles, pools and ponds etc. The latest resin technology has been utilised in EpoxiPrime to produce a product with low environmental impact and a primer capable of forming an osmotic barrier for floors, pools and ponds or where required.
EpoxiPrime is designed to:
• Be used as a primer for difficult surfaces.
• Promote adhesion to epoxy, polyester, glass, tiles and damp (not wet) cementitious surfaces.
• Exceptional Internal strength and adhesion
• Forms an osmotic barrier against moisture
• Pools
• Floors
• Glass
If primer or top coat are left to dry longer than the specified times they must be sanded before
subsequent coats are applied.
Using EpoxyPrime as an osmotic barrier – Porous surfaces (Swimming Pools and Ponds)
Osmoses occur when water migrates through concrete or brick and cement to a sealed surface above, for example: A painted floor with no Damp Proof Course (D.P.C) under the floor, swimming pool or pond. Pressure from osmosis has been recorded (in the worst cases) at 20mPA, more than enough pressure to
destroy the concrete and off course any coatings on its surface. Epoxy Prime has been formulated to tolerate light moisture in the surface it is applied to. Epoxy Prime, applied at the correct dry film thickness, will act as an osmotic barrier holding the pressure from rising damp back and preventing blisters in the top coat. This is achieved by its adhesion to the concrete being equal to that of the concrete’s internal strength. The number one failure of pool paint products is the tendency to form blisters from Osmotic pressure, it is therefore vital to apply Paintcor EpoxiPrime to a pool before applying Paintcor PoolCure.
Osmotic Barrier on Pools or Floors
1. Ensure floor and walls of the swimming pool are free of any dirt, oil, algae or dust. Should algae be present, then treat with Ushevu (algaecide) and remove. (See Ushevu Data Sheet on www.paintcor.co.za.)
2. The surface must be raw and unsealed.
3. Acid wash the surface well with neat Pool Acid using a nylon bristle broom, rinse well with clean water immediately after use and allow to dry. (Use protective clothing, particle mask and eye protection).
4. Sand rough areas to smooth. Remove sanding dust.
5. Repair any damaged areas with a suitable patching compound.
6. Mask surfaces you do not wish to paint.
7. Mix Resin (Part A) and Catalyst (Part B) as per point 1.5 above. 8. Once resin and catalyst have been mixed you have 40 minutes at 25°C to apply PoolCure primer before gel time is reached and you will be unable to apply the product. Reducing the volume of mixed primer and keeping the product cool before application will help slow the gel time down. (Reducing volume – splitting mixed product into roller trays).
9. Using a mohair roller or block brush, apply 1 coat of Paintcor EpoxiPrime to all areas being painted at a rate of ± 5m² per litre but not more than 6m² per litre. Allow 6 hours at 25°C to dry or until it can be walked on. 10. Now apply a second coat of EpoxiPrime to the surface at ± 5m² per litre but no more than 6m² per litre. In order for EpoxiPrime to form an osmotic barrier it should be applied to the correct dry film thickness, that being 440g per m² (2 x coats at 4.4m² – 4.5m² per litre).
11. Remove masking tape immediately after application of the Primer.
EpoxiPrime will spread further than the prescribed 5m² per litre on the second coat because the surface will no longer be porous, it is therefore recommended to apply a third or even a fourth coat of primer to achieve the correct film density to create a proper osmotic pressure barrier.
Allow the final coat of primer to dry for 6 hours at 25°C but no more than 24 hours before application of the first PoolCure Epoxy top coat. Should EpoxiPrime be allowed to dry for more than 24 hours at 25°C before application of PoolCure or EpoxiPrime, then EpoxiPrime must then first be sanded.
Failure to adhere to these instructions could result in coating failure. (See PoolCure Epoxy Top Coat Data sheet before application).
Non-porous surfaces (Glass, Tiles and Melamine)
1. Remove all loose or peeling paint, if any.
2. Wash the surface well to remove all dirt and surface latencies. Tiles and glass must be cleaned with Lacquer Thinners after washing. Allow to dry.
3. Mask the surface you do not wish to coat, with masking tape.
4. If coating over old paint (e.g. Epoxy or Polyester etc.), first sand old paint well and remove sanding dust.
5. Mix Resin (Part A) with Catalyst (Part B) well. Make sure all catalyst is poured into the resin and well mixed with a flat paddle. Failure to ensure this is properly done, will lead to a primer that will not cure properly. Do not use a broomstick.
6. Apply 1 thin coat of Epoxy Prime to all surfaces to be coated at a rate of 15m² per litre. You have approximately 40 minutes at 25°C to apply the mixed Epoxy Prime before gel time is reached, therefore, only mix as much as can be used in 40 minutes. Epoxy Prime will run if applied too thick
7. Allow Epoxy Prime to dry for 6 hours at 25°C but no longer than 24 hours before over coating with PoolCure Epoxy coating (See PoolCure Data Sheet).
8. Remove masking tape immediately after application of the Primer.
Over-coating EpoxiPrime with an ACRYLIC or ENAMEL based paint on non-porous surfaces
1. Prepare the surface and apply Epoxy Prime as per surface preparation for non-porous surfaces above (1 – 6). 2. Allow Epoxy Prime to dry to “tacky” (± 4 hours @ 25°C), you must be able to leave a fingerprint on the surface of the still curing primer, then apply 1 coat of high-quality adhesion promoted acrylic (water based), good quality Enamel or Polyurethane Alkyd. 3. Allow 6 hours at 25°C to dry before applying a second top coat.
• Do not apply EpoxiPrime at or below 10°C or allow Epoxy Prime to cure below 10°C with relative humidity above 60%. • Wear protective gloves and eye protection. • Avoid contact of Epoxy with skin. • Work quickly, be aware of pot life. • Only mix enough product for the surface area being coated.
• Do not mix the catalyst into the base and close the tin, pour the mixed product out into rolling trays immediately. Mixing the catalyst with the base and closing the tin may lead to the tin building pressure and exploding. • See SDS (Safety Data Sheets) for further information on www.paintcor.co.za.
Should the primer be left to dry beyond “tacky” (can no longer leave a fingerprint on the surface of the primer), delamination of the non-epoxy top coat from the primer may occur.
Drying and curing times are quoted at 25°C. At higher than 25°C, drying and curing times will shorten and at lower than 25°C, drying and curing times will take longer.
Mixing Ratio: Catalyst (Part B) 35.5gms to 100gms of resin (Part A)
Leaving EpoxiPrime tins in the sun before application will cause the product to warm up, this leading to accelerated drying times, likewise, cooling the product down before mixing will result in extended drying times.
GUARANTEE As osmotic pressure can get higher than the force required to destroy concrete, EpoxiPrime cannot be guaranteed unless there is an additional D.P.C. barrier used in the construction of the floor or pool.
APPLICATION EQUIPMENT Varnish/Fiberglass Brush or Mohair Roller
CLEAN EQUIPMENT Clean all equipment immediately after use with Paintcor’s’ Etch Thinners or Lacquer Thinners.
STORAGE Keep stored in cool, dry conditions and away from children. FLAMMABLE PRODUCT KEEP AWAY FROM OPEN FLAME.
