Mix 50/50 with water & apply by roller or brush to seal and protect porous concrete, sandstone, wood & stone. Cement can be added to this if surface damage is evident.

FOR THIN FLOORING SECTIONS & SCREEDS PLUS REPAIR, RENOVATION AND PROTECTION ON SILAGE PIT FLOORS
Q/POL is a multi-purpose product used from a sealer to a heavy screeding mix. The type of mix will be determined by the substrate roughness. i.e. For a floor starting to lose its top a polymer and neat cement mix would be appropriate. A floor with excessive damage a polymer/sand/cement or even a polymer/granite chip/cement mix would be required.

APPLICATION & MIXING - FLOOR SCREEDS

Dust and loose or weak areas must be removed and the surface should be dry. Unsound bases should be cut out and made good prior to final screed.
PRIMING - The sub-floor must be primed to ensure strong bonding of the topping. Add a 1.1 mixture of Q/POL and water to an equal volume of cement and mix into a wet slurry. Dosage 0.25L Q/POL per sq.mt. The topping must be applied onto a wet slurry, therefore only prime as much floor as required. Should the primer mix set, further primer should be applied.

MIXING - Hand mixing is very reliable. Machine mixing gives equally good results if care is taken to avoid air entrapment (i.e. do not mix for longer than 3 minutes). Mix the cement and aggregate thoroughly first, then add the recommended amount of Q/POL. Add sufficient water to give a mix which just holds together when squeezed in the hand.
APPLICATION - For screed 8mm plus, spread the wet mix to the required thickness and compact with tamping bar. Screed off and level with a wooden float. Close the surface with a metal float and do not rework the surface further after this. In hot or very dry conditions, sheet the newly laid area with polythene, do not flood the floor.

N.B Only dry silica or hard granite sand should be used, never use ‘building sand’ RESURFACING MIXES

The following mixes are ideal for resurfacing damaged silo floors - see over for slurry mix.

SILO FLOORS
Thin Seal 2 parts Q/POL to 1 part water with neat cement.
Skimming 50 kg Dry Silica Sand to 20kg Cement Q/POL and water 50/50 to form thicker slurry.

These mixes will form a slurry that may be brushed on with a stiff brush, squeegeed or trowelled. Pull off hard to expose the top of the stone to ensure grip. These mixes may be bulked out with sharp sand or aggregate to build into larger holes or damaged areas, plus large floor joints.

APPROX COVERAGE - 18-50 sq metres per 20ltr Q/POL HEAVIER MIXES and COVING - (See recommended mixes)

Q/POL may also be mixed into render type mixes for the base of walls, large voids and floor and wall joints (with latter overcoat with HYTECT OR Q/SEAL P1)

USAGE TIPS

1. As damage varies throughout most pits, mixes can be changed to suit accordingly.
2. Glass bottles form a good coving to protect bottom of pit walls, and should be overcoated with Q/SEAL for maximum protection.

3. In hot weather, especially in unroofed pits it is advisable to cover with polythene to prevent crazing. If crazing does occur, overcoat with neat Q/POL once cured.
4. On coving t is recommended all mixes be overcoated with a coat of Q/POL and water 50/50 or Q/SEAL once cured.
