DESCRIPTION
Protectakote is a single pack polyurethane which cures into an attractive, tough, textured coating, with excellent abrasion and chemical resistance, and non-slip qualities
Versions:
- Spray, for application by a wide nozzle underbody (Schutz 4mm bore) spray gun, which screws directly onto the 1 l can.
- Brush/Roller, for application by paint brush or 'stipple' roller, as used for stipple paints.
Colours
Black, Grey, Red, Dark Blue and Dark Green
PRODUCT USES
· Load areas of pick-up trucks for protection and non-slip properties
· Bakkie liner
· Floors and steps of transporters and busses
· Ramps for wheelchair access
· Emergency exits and fire escapes
· Non-slip areas around machinery
· Bridges, steps, walkways, decks and helicopter pads on ships
· Waterproofing and non-slip surfaces in showers, change rooms and ablution blocks
· Diving-suit repair and protection
· On rubber tread flooring for additional non-slip performance
ADVANTAGES
· Tough and weather resistant
· Easy to apply, no skilled labour required
· Will not taint water or food once cured
· Bonds to most surfaces except unprimed metal
· Non-slip
· Can be overcoated
· Resists many solvents, good chemical resistance to organic and inorganic acids
· Abrasion resistant
COVERAGE
Total coverage:
About 1m2 / l applied in two coats i.e. 2m² / l per coat.
SURFACE PREPARATION
Substrates differ significantly, and so all new applications should be tested first. All surfaces must be sound, dry and free of oil or grease.
Cement:
Old and new cement or concrete surfaces must be acid-etched rinsed well and dried. Cement plus primer: Protectakote exhibits good adhesion to acrylic, epoxy and polyurethane primers.
Metal:
To be free of millscale, rust, grease and well abraded.
Timber:
Abrade before applying Protectakote.
Gloss Paints and varnish:
Abrade to remove all gloss.
Rubber:
Clean well using detergent or cleaning solvent. Allow to dry. Test adhesion first.
PRIMING REQUIREMENTS
All primers to be selected, applied and overcoated to manufacturers specifications.
Mild Steel, galvanised steel, aluminium, stainless steel and fibreglass: Use Metcote as per instructions.
Cementitious and wood surfaces: Use Duraprime Epoxy Primer as per instructions.
APPLICATION INSTRUCTIONS
Ensure substrates have been prepared, tests for adhesion completed and areas not to be coated have been masked off. Stir well before use.
Spray Version:
Screw spray gun onto can, and attach airline providing a minimum of pressure of 5 bar. Protectakote should be applied in thin coats to prevent "mudcracking" during drying. Depending on the application, two or more coats can be applied, allowing time for all solvents to evaporate between coats.
Intercoat time approximately 2 hours (when touch dry) depending on ambient conditions.
Brush/Roller:
Protectakote should be "laid" onto the surface with a brush (do not brush backwards and forwards as with an enamel paint). Two coats will result in a final dry film thickness of 0,75mm to 1mm. Second or subsequent coats should be applied at right angles to the previous coat.
Roller:
If applied with a stipple roller, application is quicker and the final texture rougher with greater non-slip characteristics. Intercoat times approximately 2 hrs depending on ambient conditions.
Curing time:
Protectakote cures with atmospheric moisture. Without accelerator the coating will be touch dry in about 2-4 hrs, allowing light traffic after 12 hrs, and achieves full strength and chemical resistance in 4-7 days, but normally coating can be put to use after 24 hours.
Accelerated cure:
In areas of low atmospheric moisture or when shorter curing times are required, an accelerator can be added. This is available from manufacturer or supplier.
Overcoating and repair:
Protectakote can easily be repaired or overcoated. The old surface should be well cleaned and then abraded by wire brush or sandpaper, damaged surfaces must be cut out to provide an area without loose edges. Follow application instructions. If Protectakote is left for more than 24 hrs after coating, it should be abraded before recoating to aid intercoat adhesion.
SOLVENT/CLEANING
Protectakote can be cleaned in its uncured state using Duram Solvent.
PRECAUTIONS
· Do not clean surfaces with Lacquer thinners.
· Do not apply to bare metal without an appropriate primer.
· Protectakote is highly flammable in its wet state, solvents released during spraying, observe all fire precautions.
· Remove any overspray immediately, Protectakote is very difficult to remove once cured.
· Once opened use Protectakote within 2 hours or 1 hour if accelerator is used.
· Ensure good ventilation to prevent build up of flammable solvents.
· Protect from moisture and do not expose to temperature above 50 º C.
· Wear goggles, rubber gloves.
