S-CRETE MF

Substrate will normally be concrete or polymer modified screeds with minimum compressive strength 25N/mm² and pull-off strength 1.5N/mm². If substrate moisture exceeds 4%, use Duraflor NWB 21 as a moisture barrier. For floor in need of repair above 10mm use Duraflor EM. Preferably vacuum shot blast the surface with non-impact method. Concrete surface planer, grit blasting and surface grinding or other mechanical means until a profile is evident can be satisfactory. Substrate must be clean, free from dust, oil, water, paint residues, loose constituent s or any contaminants. Prepare grooves, 5mm wide X 5mm deep, at all edges, bay joints columns, doorways, and drains for anchoring purpose.

IMPORTANT:

Old floor needs thorough inspection for its integrity providing an ideal substrate for maximum adhesion. It has to be free from all contaminants. Grooves 5mm wide and 5mm deep have to be created diagonally into the floor every 1m² area of the floor to facilitate mechanical bonding.

Add Part A, Polyol, to a clean mixing drum. Add Part B, isocynanate, to the drum and mix for 1 minute until uniform using a helical spinner. Add the pigmented Part C powder and further mix for 1 minute to achieve a fully homogenized consistent mortar. Scrap out residue of previous mix from the sides of the drum and discard before the next pack.

Apply S-CRETE MF within its pot life. Spread the composite matrix to thickness 3~6mm and consolidate with pin rake or notched squeegee set to the correct depth. Immediately release air by spike rolling.

All S-CRETE MF floor should be applied onto cured UNIPRIME 134 or AQUAREX 1001 NWB, which has been broadcasted with silica sand.

S-CRETE MF should not be applied on material or floor temperatures below 10°C. Temperatures should not fall below 5°C in the 24 hours after application. Service temperature is depending on thickness but may be up to 60°C on intermittent splash. Not for immersion.

At 6 mm : 60ºC max. & -5ºC  
At 3 mm : 50ºC max. & -5ºC

All moving joints must be carried through the S-CRETE MF and properly sealed. Construction joints and cracks may be covered but if substrate movement occurs, the S-CRETE MF will reflect the crack.

CHEMICAL RESISTANCE

S-CRETE MF will resist spillages of:

1. Dilute and concentrated acids: hydrochloric, nitric, phosphoric and sulphuric.
2. Dilute and concentrated alkalis, including sodium hydroxide to 50% concentration.
3. Most dilute and concentrated organic acids.
4. Fats, oil and sugar.
5. Mineral oils, kerosene, gasoline and brake fluids.
6. Most organic solvents.

Resistance is maintained in many cases to 60ºC, which should be regarded as the maximum service temperature.

Clean all tools with acetone, xylene or other solvents prior to material taking a hard set. Small unreacted Part B in container to be decontaminated with a 5% solution of washing soda (sodium carbonate) prior to disposal. After material has set it is virtually impossible to get off and must wear off over time.

Regular cleaning and maintenance will prolong the life of all resin floors, enhance the appearance and reduce the tendency to retain dirt.

Some of the component s of this product may be hazardous during mixing and application. Always use with suitable protective gears. Close container tightly after use. Keep out of reach of children. For further information, refer to the product Material Safety Data Sheet, available upon request.
