Stripping and sealing floors effectively

Achieve Benefits of appearance and value by applying a high quality floor sealer to a floor. Protect and enhance a valuable asset. Floors are exposed to sustained abrasion from foot and trolley traffic, spillages and dirt which, without protection, can cause scratching and dulling of the floor surface and even wear it away.

Once coated with a suitable sealer, the floor is protected from these threats.

Furthermore, the surface becomes easy to clean with soil readily washed away, the

colours of the floor can be enhanced, or you can choose a natural look sealer. The floor can have improved shine.

By implementing a full protection system using complimentary sealers and

maintenance products, this protection and enhancement will last a prolonged period before either maintenance sealers are added, or full stripping and resealing is necessary.


The following is a guide for stripping and sealing floors to achieve the best result.


Floor Types: Terrazzo, marble, agglomerate marble, limestone and sadler tile.

Sealing Equipment:

 Polish mop & wringer bucket – or – Polish fringe mop & watering can

 Buffing machine pad

 Wet floor signs

Stripping Equipment:

 Dustmop or broom

 Stripper mop

 Scraper

 Black handpads

 Wet floor signs

 Rotary scrubbing machine black pad

 Cardboard

 Rinse mops

 Wringer bucket

 Wet vacuum or Autoscrubber

Please Note:

 Always use a fresh mop for both stripping and sealing.

 A base sealer like Impact must be used so the film will bond to the floor and

not flake off.

 Avoid sealing very cold floors (below 9˚C). If you must seal a cold floor, lay

very thin coats at least one hour apart.

 Coverage: On average, one litre of sealer will cover 50 square metres of floor

(one coat only). In practice, the first coat will require more sealer as a rough floor absorbs liquid, and the last coats will require less. Porous floors will take more sealer.

  1. Strip Floors
  2. Sweep the floor to remove any rubbish.
  3. Scrape off any chewing gum and labels.
  4. Erect ‘wet floor’ signs and barricades to keep people off the floor.
  5. Place a large piece of cardboard on the floor next to the area being stripped.

When you walk off the area with stripper on your shoes, step onto the

cardboard to dry off your shoes. This will prevent ‘footprints’ appearing all

over the floor.

  1. Using a wringer bucket with 12 litres of cold water in it, add stripper in

accordance with manufacture dilution guideline on sealer to be stripped.

  1. Dip a stripper mop (old or used mops are OK) into the bucket of solution.

Remove mop from bucket without wringing and let stripper pour all over

floor. Repeat this process until the entire area is covered with a thick

coating of stripper solution.

  1. If stripping a large area, divide floor into easy to manage sections and strip

one section at a time.

  1. Leave the stripper on the floor for ten minutes, giving time to attack the

sealer. Spread it with the mop if it dries or runs – always keep the floor

evenly wet. During this time scrub the feet of shelves and fittings to remove

old sealer and dirt. Do NOT leave it on the floor longer than 20 mins or the

stripped sealer will start to reform.

  1. When dwell time is up, scrub the floor with a scrubber (turn vacuum off) and

black pads. Scrub the whole floor, starting at the point nearest to the power

point if using an electric machine. Spend longer scrubbing the edges because

the sealer will be thicker there.

  1. Test the floor by wiping the stripper aside and scraping with a coin to see if

all old sealer film has been removed. If not, keep scrubbing. If this process is

not done properly, a second stripping process will be necessary.

  1. Wet vacuum all the stripper slurry up off the floor.
  2. Pour cleaner water all over the floor then vacuum this up to rinse the floor.

It is important to neutralise the stripper otherwise residue may attach the

sealer when applied. A neutralising chemical will assist the process.

  1. Applying a base coat
  2. Let the floor completely dry.
  3. DO NOT buff the floor. Put up barriers to keep people off the floor being


  1. Mop on one coat of the base sealer. This can be done with a clean polish mop

and wringer bucket (which is best) or a clean fringe mop and watering can.

Spread the pour line as soon as possible after pouring. Lay the sealer up to

the edges. Lay sealer as thinly as possible – never in pools as it will take a

long time to cure. Do not walk on floor until it is dry.

  1. Let the first coat dry. It must not only be dry but also tack free, or not sticky,

before laying the second coat. If it is not dry, the second coat will bond with

the first instead of creating a second hard layer. Test by placing your hand

on the floor. Wait an extra 10 minutes after it is touch-dry before laying the

next coat. On very porous floors, it is advisable to allow at least one hour for

the first coat to dry properly.

  1. Mop on a second coat of the base sealer, but this time stay 30cm (12 inches)

away from edges, along walls and furniture. The second coat, if being

applied with the bucket and mop, should be laid at 90 degrees to the way

the first coat was laid.

  1. Again, let the base coat dry until it is not sticky to touch, then give it 10

minutes more time.

  1. Applying the top sealer using a polish mop. At this stage there is a choice of another

base coat layer or starting to add a different surface finish like high gloss. Very High

gloss coats are not as resilient as the base coats but provide the appearance.

  1. Mop on two coats of base/high gloss, allowing each coat to dry before laying

the next. Keep 30cm from edges, except for the last coat which should go up

to the edges.

  1. Give the floor six hours or more to cure, then buff the floor with Blue Ice or

Champagne pads (on ultrahigh speed buffer) or red pads (on medium-speed

buffer). The longer drying is necessary as pads have abrasive properties so

the surface must be dry and intact.

  1. Clean mops, pads and buckets with hot water and hang them up to dry. If

fringes are to be used again soon, place them in a clean black garbage bag

and seal the end so the fringe will stay wet until next time it is used.

  1. After 1-2 weeks, the floor can be buffed with Jackeroo Lite, Gorilla Lite or

Combo Burnishing pads (or equivalents
