High Performance Floor Coating

S l h fl d l l h The flooring should be a sound concrete or fresh plastered surface and be free from oil grease laitance dust blowholes voids cracks

Select the flooring and calculate the area

and be free from oil, grease, laitance, dust, blowholes, voids, cracks, damaged spots, old loose paint, water, high moisture in concrete and high rough finishes should be leveled using screed or mortar.

Surface Preparation of Concrete

The concrete surface must be prepared mechanically using abrasive blast cleaning, scarifying or grinding (Diamond grinding)

Substrate deeply contaminated with oil and grease must be cleaned by means of flame jetting followed by cleaning with detergent water.

Weak concrete must be removed

All voids, dents are to be repaired and surface leveling must be carried out by using appropriate productsby using appropriate products

All dust, loose and extraneous materials must be removed by brush and or vacuum

Fresh laid concrete or flooring plaster for the full cure before primer application and the normal 28 day cure schedule be followed unless otherwise specified

Surface Preparation of Concrete SSPC SP 13

Joint standard with NACE # 6

Surface shall be free from form oils, air borne contaminants, Laitance and Loose concrete

Estimation of Moisture content in concrete

ASTM D 4263 is a test method to qualitatively indicate the q ypresence of moisture by use of plastic sheet method. ASTM F 1869 is a qualitative test to measure moisture vapour

The latest device is handy and easy to use instrument which The latest device is handy and easy to use instrument which does not use pins and does not damage the substrate under test. The gauge is placed onto the material to be evaluated

d i kl i di t th d f i t i t fib and quickly indicates the degree of moisture in concrete, fibre glass or wood down to a depth of 3cm (1.2”).

What not to do?

Do not apply primer on substrate having moisture content >5%.Not to apply mixed coatings beyond usable ‘Pot Life’ period.Do not apply when the substrate temp is below 150C and greater than 350C.Do not add solvent or thinner in any of the coatings.After application of Floor Coating avoid over spiking/rolling or else you may develop orange peel effect in the finishDo not apply at relative air humidity >80%.Do not apply on the substrate suffering from rising dampnessIf the over coating interval between primer and floor coating or g p gepoxy screed and floor coating is greater than 24 hrs, then the primed or the screed surfaces must be roughened or emery’d and cleaned.
