Considerations before choosing a floor:-
- Will there be heavy wear?
- Is area subject to moisture?
- Does the floor need to be sound barrier?
- How easy is it to clean & maintain?
- To what degree floor need to be slip resistant?
- Can it cause allergies or asthma?
- How durable is the product?
- Is it suitable for subfloor?
SUBFLOOR:- A subfloor is what’s below your flooring material.
Advantages of subfloor:
- Provides drainage abilities.
- Warms flooring material upto 30%.
- Protects against moisture seepage.
- Lengthens the life of new flooring.
- Increase its feel & quality.
Examples of subfloors:-Plywood, Plank, Oriented Stran Board, Concrete.
- Plywood: Made from thin sheets of usually pine wood those are glued together, forming 4ft x 8ft sheets.
- Plank:There are ¾ inch thick x 4 – 8 inch wide southern pine board which are nailed together.
- Oriented Stran Board: It is a bunch of wood chips glued together.
- Concrete: Consists of slabs of 4 – 6 inch thick concrete pour. It may tend to absorb moisture which might take long to dry.
Classification of floor Finishes :-
| HARD | SEMI – HARD | SOFT |
| Cementitious (Terrazzo & Granolithic)Stone (Marble. Slate etc)ResinBitumasticMagnesiteWood | Thermoplastic tilesVinylRubberLinoleumCork | Carpets |
Seals & Polishes: – (1 mm coating)
Seals are used to protect the flooring from dirt, moisture, spillage, stains, scratches, dents etc.
Polishes are laid over the seals. It extends the life of seals by 2 – 4 Year
- HARD FLOORS
- STONE – Long life and natural in appearance. All stones are heavy and must be put on a concrete sub floor. For e.g.
Marble:
- Composition: Calcite & Calcium Carbonate.
- Available in wide range of colors.

Porcelain:
- Unglazed
- Dense
- Imperious
- Fine grained & smooth.
- Fire hardened – very hard
- Can be cleans at high pressure.
Quarry:
- Most common colors are dark red, brown & grey.
- Fire hardened – very hard
- Can be cleans at high pressure.
- Resin Flooring:
- Consists of synthetic resins, usually epoxy, polyester or polyurethane with hardness by using hardness.
- Sometimes vinyl & marble chips are included.
- Unaffected by spillage of water, food, alcohol & chemicals.
- Inspite of being shiny they are non-skid.
2. Bitumastic:
- Joint less flooring consists of asphalt rolled in hot plastic state.
- Soft in texture.
- Impermeable to water.
- Softens with heat & dents easily.
- Harmed by spirits, oil & acids.
- Cost is low.
3. Magnesite:
- Consists of wood flour & other fillers mixed with burnt magnesite.
- Hardwearing & great compressive strength.
- Thermally insulating, non skid, frame retardant & spark proof.
- Extremely porous so no washing.
- Harmed by water, chemicals & abrasives.
Cleaning of Hard floorings
- Daily cleaning – Sweep and damp mop/ Vaccum cleaning
- Periodically – Wash/ scrub with detergent suds. Rinse Dry and Polish.
- Sealed to make the floor non slip and resistant to dirt.
- For tiles care to be taken to clean the grouting regularly with a detergent and tooth brush.
Semi Hard Finishes
- Resistant (except thermoplastic tiles).
- Good appearance.
- Unaffected by insects, pests & fungi.
- Easy to clean
- Less permanent than hard floorings
Thermoplastic Tiles:
- Made from asphaltic binds with inert fillers & pigments.

Cleaning of Semi Hard Floors
- Daily cleaning – Sweep and Damp Mop / Vaccum cleaning
- Periodic cleaning – Soft scrubbing with Neutral detergent lather. Rinse with a damp mop. Polish. If it is a sealed flooring use a self shine polish occasionally
- For rubber floorings wash only when dirty and don’t over wet
SOFT FLOOR FINISHES
These are resilient floorings and include all types of carpets, rugs and mats. They are quiet and slip resistant.
Carpets
- Consist of a backing and a surface pile.
- Backing may be jute, nylon or polyester.
- Pile may be of wool, cotton, nylon or polyester.
- Used for their appearance, warmth, safety factor and sound insulation.
- Care and Maintenance –
- Regular maintenance program since they are easily damaged
- Do not drag anything on a carpet
- New carpets should be lightly cleaned with a hand brush or a carpet sweeper. Trim off loose tufts
- Vacuum clean daily.
- Periodic cleaning includes shampooing , hot water extraction or dry powdering
- Shampooing – Shampoos can be of two types Liquid and dry foam. Liquid shampoos produce very little foam but tend to leave a residue that traps dirt making it necessary to clean carpets frequently. Dry foam shampoos are also liquid but leave a dry foam on the surface of the carpet after application – hence the name dry foam. The foam loosens and lifts out the dirt, holding it on the surface of the carpet pile until it can be removed by dry suction. Dry foam shampoos contains some solvent in addition to the detergent to assist in removal of greasy soil. They also take less time to dry
- Hot water extraction: done by a hot water extraction machine which injects a non foaming shampoo solution at high pressure through the carpet. Simultaneously it extracts the solution and soil.
- Dry powdering: A powder containing absorbents (saw dust), solvents & drying agents is sprinkled on the carpet & left for 15 to 20 minutes. The powder absorbs the grease & dirt & latter vacuum cleaned.
Floor care life cycle
Stripping:Removal of all existing finishes & seals. Clean thoroughly & allow to dry.
Scrub & Recoating: Consist of top scrubbing & removing any dirt/foreign material & re-applying finish to renew & extend the life of coating.
Restoration: Performed when routine maintenance no longer gives desired level of appearance.
Routine Maintenance: Remove dirt, foreign material. Includes daily cleaning. Improves appearance & life is increased may include dry mopping & wet methods.
Coating: Apply fix, thin uniform coats & give adequate drying time.
