Overview
KingProof PP100 is a fast-curing, cold applied, one component, thixotropic, moisture curing, modified polyurethane fluid based on elastomeric waterproofing membrane.
It produces a tough rubber - like seamless finish with excellent surface adhesion to most types of substrates and excellent elasticity.
Where to use
Waterproofing and protection of
- Vertical and horizontal substrates.
- Roofs.
- Cementitious substrates.
- Wet areas and irrigation channels.
- Bathrooms.
- Bitumen membranes (for repair also).
- Foundations.
- Closed spaces with high humidity like planters.
Why use it
- Easily applied by brush, squeegee blade or airless spray.
- Fast curing.
- Excellent adhesion to almost any surface.
- Excellent thermal resistance and service temperatures.
- Stable at a wide temperature range.
- Excellent mechanical properties, high elongation, high tensile and tear strength, high abrasion resistance.
- Thixotropic consistency, easily applied on vertical surface and complex shapes without running or bubbling.
- As a pitch based system, it gives an excellent chemical resistance.
- Provides a uniform, joint free, seamless membrane.
- UV stable, does not harden or become brittle.
- Good oxidation stability.
- Can be easily repaired if damaged.

How to use
Surface preparation
The surface should be clean, dry, sound and free from oil, grease and wax contamination.
Cement laitance, loose particles, mould release agent or curing membranes must be removed. Fill surfaces irregularities with a suitable product. New concrete structures need to dry for at least 28 days.
Priming
For porous concrete substrates the following priming procedures can be adopted; mix KingProof PP100 and KINGKRETE solvent PU with a ratio of 1 : 1.
Use KingProof Primer PU for bituminous surfaces, old and failed membranes, metal, glass and timber.
Application
For spraying with airless spray machine, KINGKRETE Solvent PU may be used with 5 - 10%. For any mixing done on site, low speed (300 rpm) mixer or electric drill should be used. Apply at least two coats. it is not to leave more than 24 hours between coats.
KingProof PP100 is a UV stable, and it can be left exposed to UV light. However, if extra heat and light stability is needed, KingProof PUT100 can be used to overcoat cured KingProof PP100.
It is recommended to use KingFlash V as a reinforcement by embedding it into the still wet membrane, for upstand joints, complete coverage of old application, reinforcing joints on timber, etc.
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.
