Overview
KingFloor Primer S is a clear high performance solvent based epoxy primer designed to improve adhesion of various types of KINGKRETE epoxy range including coatings, self-smoothing and trowel applied products.
Where to use
KingFloor Primer S is used as a prime coat to aid improving adhesion of subsequent epoxy layers. One or two coats should be applied depending on surfaces' porosity.

How to use
Substrate preparation
The substrate must be clean, dry, even, dense and free from oil, grease, dust and other contaminants. A clean surface will ensure maximum adhesion between the substrate and the coating. Concrete floors must have a minimum compressive strength of 25 N/mm² and a maximum concrete relative humidity of 75% (max. moisture content of 5%), relative humidity can be measured using a hygrometer. Concrete relative humidity should be less than 75% for concrete 28 days old or more.
Surface preparation
Unsound layers and contaminated concrete surfaces must be prepared using mechanical surface removing equipment. Acid etching can be used only in well ventilated areas. Areas deeply contaminated by oil or grease, should be treated by hot compressed air.
Mixing
Prior to mixing, stir individual components of KingFloor Primer S. Take care to ensure that bottom and sides are thoroughly scraped, transfer the entire content of hardener into the base and mix for 2 - 3 minutes using slow speed mixer fitted with suitable paddle.
Application
KingFloor Primer S should be applied by brush or short hair lambs wool roller.
Spread evenly at the recommended coverage rate, avoiding any primer ponding on the floor. Highly porous surfaces may require two coats of Primer.
Cleaning
KingFloor Primer S can be removed by KINGKRETE solvent prior to setting.
