Overview
KingProof PUT100 is a one component, high solids, polyurethane coating that cures by reacting with the humidity in the atmosphere to form a transparent, strong elastic film with excellent UV resistance.
KingProof PUT100 is based on pure elastomeric hydrophobic polyurethane resin that provides excellent mechanical, chemical and thermal resistance properties.
Where to use
KingProof PUT100 is designed for waterproofing and protection of:
- Exposed roofs, balconies.
- Tiles.
- Natural stone.
- Wood, metal and galvanized steel.
- Internal and external applications.
- Terraces.
- Concrete.
Why use it
- Transparent.
- One component – ready to use.
- Excellent weather and UV resistance.
- Excellent thermal resistance.
- Easily applied.
- Excellent mechanical properties.
- Cold Resistance: the film remains elastic down to -40°C.
- Good chemical resistance.
- Water vapor transmission.
- Can be applied in thick, bubble-free, coats.

How to use
Method of use
Substrate Preparation
All surfaces should be clean, dry, sound and free from oil, grease and wax contamination, surfaces must be free of any dust or loose particles before product application. Use suitable methods like vacuuming or sweeping. Maximum moisture content should not exceed 5%.
Any possible surfaces irregularities or defects should be repaired before application. Consult KINGKRETE's Technical Department for the best repair material.
For Concrete Surfaces: The surface must be structurally sound, free from oil, grease and other forms of contamination. Cement laitance, loose particles, release agent or curing membranes must be removed.
REMARKS
- New concrete structures need to dry for at least 28 days.
- Concrete substrate should be below 85% Relative humidity.
- Concrete substrate temperature should be between 5 - 35°C.
Mixing
Stir KingProof PUT100 well before use, mix for 2 - 3 minutes manually or use a slow speed mixer fitted with suitable paddle until a uniform consistency is achieved.
No thinning is required but KINGKRETE Solvent PU may be used.
Application
KingProof PUT100 should be applied over the prepared surface using a roller in 2 successive layers with a minimum total consumption of
0.8 litre/m2.
For nonporous substrates
Apply KingProof PUT100 as soon as KingProof Primer PU coat dries (after 15 - 20 min). Do not leave more than 24 hours between coats.
For Porous substrates
Apply KingProof PUT100 onto the substrate after a minimum of 12 hours and not later than 2 days from applying KingProof Primer PU. Do not leave more than 24 hours between coats.
PRIMER
The following priming options are available depending on the substrate surface:
For nonporous substrates
Non porous substrates such as glazed ceramic tiles should be primed using KingProof Primer PU.
Apply KingProof Primer PU at rate of (50 - 60 ml/m²), wipe the entire surface with the primer using a clean cloth, do not leave any pools of fluid and do not leave any untreated spots.
For porous substrates
Porous substrates such as marble and natural stones should be primed using KingProof Primer PU.
Apply KingProof Primer PU at maximum rate of (200 ml/m²) using brush or roller, do not leave any pools of fluid and do not leave any untreated spots.
Cleaning
All tools should be cleaned after finishing with paper towels and then wipe by using KINGKRETE Solvent PU. Do not try to clean rollers.
Limitations and notes
- Do not use on unsound substrates.
- Since KingProof PUT100 cures with moisture, low humidity conditions will extend the tack-free time and recoat time.
Coverage, packaging and storage
Consumption
Minimum total consumption: 0.8 - 1.0 litre/m², to achieve a dry film thickness of 0.65 – 0.85 mm. Consumption will depend on substrate type and texture.
Packaging
KingProof PUT100 is available in 20 litre pails.
Storage
Shelf life is 1 year when stored under cover, out of direct sunlight and protected from extremes of temperature.
Failure to comply with the recommended storage conditions may result in premature deterioration of
the product or packaging. For specific storage advice consult KingKrete's Technical Services Department.
Health and safety
As with all chemical products, care should be taken during use and storage to avoid contact with eyes,mouth, skin and foodstuffs. Treat splashes to eyes
and skin immediately. If accidentally ingested, seek
medical attention. Reseal containers after use. Use in well ventilated areas and avoid inhalation.
