Remove any loose concrete material from repair area
Clean area with a Nyalox brush or wire wheel and vacuum free of dust

Pigments such as our Polish Dye, or our Indoor/outdoor dye can be added to the “B” side prior to mixing to pigment the product (only use solvent based dye products)
Sand can be added for strength and volume. 3 parts sand and one part mixed Instant Medic hard will make a trowelable (slightly runny) mix. It is not suggested to mix too much sand.
Other “dry” products such as portland, tile grout, etc. can be added for color and texture
Only mix small batches of Instant Medic Hard at one time (start off with no more than 8 oz’s in total). This product dries very quick

3. Pour Mixed product into repair area
Allow to slightly overfill.
If pouring into a crack, keep shoving more product into top of crack until it stops sinking into crack cavity

4. Clean excess product
Clean overfilled product with a diamond tool, or
A Flap disc (available at most any hardware store) on an angle grinder is also good at removing excess product. You must prep the repair product with a diamond tool not only to make it flush with the floor, but to add a profile before coating.

NOTE: Instant Medic Hard does not like Moisture. The surface itself and the products added to it (sand, polishing dust) must be bone dry. It is not recommended to use playground sand (sand from plastic bags).
