Purathane two pack gloss
URETHANE COATINGS PURATHANE TWO PACK GLOSS is two component water borne polyurethane finish developed to provide your commercial timber and parquetry floors with extremely hardwearing and long lasting protection. The rapid curing of PURATHANE TWO PACK GLOSS achieves optimal hardness up to 50% faster than single pack water borne polyurethane and higher solids provide greater resistance to wear.
Because water is used as the alternative carrier to solvent, URETHANE COATINGS PURATHANE GLOSS emits low VOC’S (volatile organic compounds) and is therefore user and environmentally friendly but retains all the durable and hard wearing benefits of solvent based polyurethane.
PHYSICAL DESCRIPTION
Appearance: Opaque liquid.
Colour: Milky white.
PH: >7
Specific Gravity @ 25ºC: >1.
PREPARATION
General:
- Check that timber is adequately seasoned as if not, any subsequent cracking warping and shrinkage may compromise adhesion.
- Ensure the surface is dry and thoroughly clean, removing all dirt, mildew, wax, grease, resin oils, tannins and dust.
- Nail holes and surface defects should be filled with water based putty.
New Floors:
Follow steps 1 to 3 above, sand the floor and fine sand, finishing with 120 grit screen back or pad and vacuum thoroughly.
Old Floors:
Follow steps 2 to 3 above and clean with hot water and detergent. Roughen surface completely with 100 grit sandpaper and fine sand finishing, with 120 grit screen back or pad and vacuum thoroughly.
If there is risk of contamination, test for compatibility by applying PURATHANE TWO PACK on a small section of floor first. If ‘craters’ or ‘fisheyes’ appear add 20mls of URETHANE COATINGS PURAMAX Anti Rejection Fluid per Litre of PURATHANE TWO PACK and refer to URETHANE COATINGS PURAMAX directions.
MIXING
Shake each container for one minute and allow each to stand for two minutes, then Mix PURATHANE PART B (BASE) and PURATHANE PART A (HARDENER) at a ratio of 10 to 1 and thoroughly stir, then allow the mixture to stand for two minutes. Always add PURATHANE PART A (HARDENER) to PURATHANE PART B (BASE). Mixed PURATHANE TWO PACK has a pot life of 2 hours (@ 25ºC and 50% R.H.). Smaller mixtures (< 2 Litres) and increased temperature and/or reduced humidity will reduce pot life.
APPLICATION
URETHANE COATINGS recommend a 3 coat system for most situations; 1st coat PURASEAL, followed by 2nd and 3rd coats of PURATHANE TWO PACK. A 2 coat system will achieve a high performance finish on hardwood when applied at the rate of 8m² per Litre.
Coat PURASEAL with either PURATHANE or PURATHANE TWO PACK.
N.B. (1) PURATHANE GLOSS, SATIN and MATT are completely compatible with each other, and can be mixed together and coated over each other. (2) PURATHANE TWO PACK GLOSS, SATIN and MATT are completely compatible with each other, and also can be mixed together and coated over each other. (3) Do not mix PURASEAL with PURATHANE or PURATHANE TWO PACK.
As an alternative to PURASEAL, URETHANE COATINGS solvent based TIMBERSEAL is a well proven fast drying sealer. As a 3 coat system TIMBERSEAL can be coated with PURATHANE or PURATHANE TWO PACK.
Application Orientation:
UV Stable, ideal for internal use, verandas, and covered patios.
Application Method: 3 Coat System
1st Coat. Decant PURASEAL directly from the container. Cut in edges with a paint edger or brush, taking care not to proceed excessively ahead of the main coating (particularly in hot and/or dry conditions). Apply PURASEAL at the rate of 10m² per Litre with a 10mm nap waterbased type roller cover or a waterbased applicator, disperse into a uniform finish taking care not to ‘overwork the coating’ allowing it to self level, and wherever possible, finish parallel with the grain. Allow 1.5 to 2 hours to dry (@ 25ºC and 50% R.H.) and prepare to recoat. Do not return unused material to the container.
It is not necessary to fine sand or buff PURASEAL unless surface imperfections or raised grain exist – if so allow 3 hours to dry and then buff with 150 grit screen back (or finer), taking extreme care not to cut through the PURASEAL as this will allow the next coat to ‘wet’ the timber which may then dry a slightly different colour.
2nd Coat. After mixing PURATHANE TWO PACK, cut in edges with a paint edger or brush, taking care not to proceed excessively ahead of the main coating (particularly in hot and/or dry conditions). Apply PURATHANE TWO PACK at the rate of 10m² per Litre with a 10mm nap waterbased type roller cover or a waterbased applicator, disperse into a uniform finish taking care not to ‘overwork the coating’ allowing it to self level, and finish wherever possible parallel with the grain. Allow 2 hours 30 minutes to dry (@ 25ºC and 50% R.H.) and buff with 150 grit screen back, vacuum thoroughly and prepare to recoat. Do not return unused material to the container.
3rd Coat. Repeat directions as detailed under 2nd Coat, finishing parallel with the grain. Allow 8 hours to dry (@ 25ºC and 50% R.H.) before providing access for light foot traffic.
Application Conditions:
Do not apply PURATHANE TWO PACK when ambient/surface temperature is below 10ºC or above 30ºC.
Do not apply PURATHANE TWO PACK if relative humidity is in excess of 85%.
Do not apply PURATHANE TWO PACK if the moisture content of timber is in excess of 14%.
Sanding:
PURATHANE TWO PACK is suitable for sanding after 2 hours 30 minutes drying
(@ 25ºC and 50% R.H.). A good indication that PURTHANE TWO PACK is sufficiently dry is when light sanding using a 150 grit screen back or buffing pad, produces a fine white powder.
USE and MAINTENANCE of a 3 COAT SYSTEM
PURATHANE TWO PACK GLOSS requires 1.5-2 days (@ 25ºC and 50% R.H.) to cure before regular use, and 4 days before using cleaning formulations. Avoid heavy traffic during this period. After the curing period sweep regularly with a soft bristle broom, and if preferred rugs/mats/carpet squares can be placed on the floor. To clean your floor, mix up to one cup Methylated Spirit into a bucket of hot water, and mop the floor regularly rinsing the mop. Use protective pads under legs of furniture. Dirt and grit are abrasive when on the soles of shoes, and can damage any coating. Accordingly mats placed at entrances can assist in removal of grit, reducing abrasion and protecting the coating.
DRYING TIME
Touch dry: 40 minutes. Through Dry: 2 hours. Sanding & Recoat: 2 hours 30 minutes (Without sanding recoat in 90 to 120 minutes). All drying times are @ 25ºC and 50% relative humidity. Reduced temperature and/or increased humidity can delay drying time.
COVERAGE
10m² per Litre.
THINNING
URETHANE COATINGS PURATHANE TWO PACK does not require thinning. In hot and/or dry conditions and very large areas where it is difficult to maintain a wet edge, add 50ml of URETHANE COATINGS PURAMATE Wet Edge Extender per Litre of PURATHANE TWO PACK and refer to URETHANE COATINGS PURAMATE directions.
CLEAN UP
Thoroughly wash brush, roller, applicator and equipment with water. If PURATHANE TWO PACK is allowed to ‘become tacky’ on equipment, first rinse off excess with water, then wash off any build up of PURATHANE TWO PACK with URETHANE COATINGS CLEANING SOLVENT or Methylated Spirit, then rinse with water. Dry all equipment before reusing.
PACKAGING
URETHANE COATINGS PURATHANE PART B (BASE) is available in 5 and 10 Litre plastic bottles and PURATHANE PART A (HARDENER) is available in 500ml plastic bottles.
SHELF LIFE
URETHANE COATINGS PURATHANE TWO PACK is best if used within 12 months from manufacture (refer to batch number on label), when stored in unopened containers under normal conditions of temperature (between 5ºC and 30ºC – DO NOT FREEZE) and humidity. Keep containers closed when not in use.
RESPONSIBLE CARE
URETHANE COATINGS are proud of a conservative tradition of responsible care, and therefore regardless that the VOC levels of PURATHANE TWO PACK are low, it is inappropriate to advise PURATHANE TWO PACK (and all other water borne coatings) is non toxic. Accordingly URETHANE COATINGS recommend that personal protective equipment is used when applying this product.
