Pro Seal Ultra - Invisible Solvent Based Penetrating Floor Sealer | For Porous Indoor & Outdoor Surfaces

Pro Seal Ultra is ready-to-use. Do not dilute. Shake well before use.

Floor sealing

1. Test first. All surfaces are different. Allow 24 hours of curing time before assessing the sample area for suitability.
2. Prepare the surface. 
   • New floors: New floor installations must be fully cured before application (minimum 48 hours). For newly poured concrete, allow 28 days before the application of sealer.
   • Existing Floors: If required, strip any existing surface coatings, and clean any inground dirt on the surface and grout lines. Protect the environment surrounding the area (e.g. carpet, walls and furniture). Ensure the surface is completely 100% dry, clean and free of any contamination, chemical or residue. Remove all stains and soiling prior to sealing.
3. Wear PPE and apply Pro Seal Ultra undiluted, slowly, and evenly to the surface using a pump-up solvent resistant sprayer, lambswool applicator or suitable process for the surface type. For edging, use a paintbrush. Apply your coats in a cross direction to ensure complete coverage e.g. 1st coat in an east-west direction and the 2nd coat north-south, waiting 30 to 45 minutes between coats. If there is any excess sealer visible 5 to 10 minutes after each coat, wipe the surface with a clean absorbent white towelling cloth or machine buff with a suitable pad (eg. lambswool or microfibre) to remove the excess. Moisten a white towel with Pro Seal Ultra or Methylated Spirits to remove any stubborn residues that have dried on the surface.

Handy tips

• Coverage: For porous surfaces (eg Sandstone and Untreated Concrete): Professional application coverage is approximately 10 to 20 square metres per litre of Pro Seal Ultra for one coat on a porous surface. 2 to 3 coats are recommended and application rates vary depending on the porosity and texture of the surface being sealed. In some instances, coverage can be as low as 5 square metres per litre and as high as 30 square metres per litre per coat. Life expectancy and correct coverage (eg. coats/app. rate) are interdependent.
  For dense surfaces: Professional application coverage can range from 20 to 50 square metres per litre of Pro Seal Ultra for one coat. On dense surfaces, 2 thin coats are recommended and application rates vary depending on the porosity and texture of the surface being sealed.
• Residue: It is not uncommon to have sealer residue left on super dense surfaces. This is where sealer has not fully penetrated into the pores of the surface or maybe you used a bit much or didn't follow the instructions to remove excess after 10 minutes. That's okay. Just grab some white towelling and rub it off. This should be done after the sealer has dried but before it has fully cured. This is usually 30 to 45 minutes after application of the coat. Ant stubborn residues can be removed within 4 hours with white towelling moistened with Pro Seal Ultra, Metho or White Spirits. Rub until the residue is removed and the surface is dry.
• Ventilation: When using Pro Seal Ultra, ensure the area to be sealed is suitably ventilated. Air conditioners are not a form of ventilation and should be turned off during application.
• Test first: Always test first in an inconspicuous area before use. Because all surfaces are different, we recommend that you always perform a small test patch in an inconspicuous area to ensure you will get the desired result. Allow 24 hours of curing time before assessing the sample area for suitability. A test patch also doubles as a demonstration. For example, pour water onto the sealed and unsealed section of the tile to show the client how the product will perform and repel liquids.
• Drying times: Allow 30 to 45 minutes between coats. Keep the surface free of traffic for 3 to 6 hours and completely dry for 12 hours after application. Pro Seal Ultra achieves a full cure after 48 to 72 hours.
• Temperature: Surface temperature must be between 5 to 35°C for successful application. Do not apply in direct sunlight.
• Guarantees and warranties: Most professional applicators of Pro Seal Ultra offer a conditional guarantee of 2 to 10 years, most commonly 5 years. Guarantees are always very conditional and subject to factors such as correct maintenance, products to be used and regular sealer top-ups. Long warranties and guarantees are not offered by XO2, we leave the conditions, warranty length and follow-up responsibilities to the professional application company to set.
• Clean up: Use solvent. Either White Spirits or Methylated Spirits (Metho). Having said this, lambswool refills and paint brushes are cheap so it is cheaper and more productive to just dispose of these as opposed to using expensive, dangerous, and time-consuming cleanup processes. Rinse off equipment thoroughly, or throw it out.
• Shelf life: 2 years for an unopened drum.
• When using a lambswool applicator, avoid excessive working in of the sealer with the applicator. This will stop any foaming.

Important. Read this before use.

• Spills should always be cleaned off the sealed surface immediately to reduce absorption.
• Pro Seal Ultra does not prevent wear or surface etching of the surface that has been sealed.
• Existing floor sealers, treatments or coatings are likely to be affected by Pro Seal Ultra. Always pre-test. Existing sealers and coatings should be removed before the application of Pro Seal Ultra.
• It is the responsibility of the applicator to educate themselves on surface suitability, surface types, application rates, application techniques, all environmental aspects, performance, value and all other issues relating to the completed job and the customer’s specific expectations.
• If you are using a pump-up sprayer, ensure the sprayer is solvent/alcohol resistant. This will mean the seals are not rubber but made of something like Teflon, nylon or nitrile. You also want your sprayer to produce a particle size of around 15 microns. Pressure should be low (30 to 45psi.) Do not mist, atomise or aerosolize Pro Seal Ultra.
• Do not allow Pro Seal Ultra to make contact with glass, metal, plastics, vinyl, painted surfaces, fabrics, etc.
• Do not pour the sealer directly onto the surface or allow the sealer to puddle on surfaces.
• Ensure all bottles of Pro Seal Ultra are kept closed when not being used and always cover the roller tray or bucket. Keep exposure to a minimum to reduce evaporation and contamination.
• Do not dilute or alter the formulation.
• Do not apply sealer if rain is expected in the next 12 hours post-completion.
• Pro Seal Ultra will not resist against hydrostatic pressure or rising damp. It is not a waterproofing agent.
• Pro Seal Ultra will not seal cracks greater than 0.025mm.
• Contaminants left on a sealed surface for long periods will penetrate the sealed surface.
• Do not use solvent based chemicals to clean a sealed surface as they will remove the sealer over time. Use Bobby Dazzler, Bonza or Too Easy for cleaning and maintenance.

How long does a sealed floor last?

When a professional applies a multi-coat application, the optimum life expectancy for a correctly sealed floor is about 4 to 7 years, and in some applications longer. For ultimate protection, apply an additional coat post-cleaning every 1 to 2 years as part of your floor maintenance routine. Application methods, weather, traffic and harsh cleaning will affect wear. Avoid solvents, strong acids and strong alkalis for longer sealer life.

If life expectancy is 4 to 7 years, how can some applicators have 20+ year warranties?

A one-off application life expectancy and a warranty length are different things. With the right maintenance and top-up frequency as a condition of the warranty, a floor can be kept in good shape indefinitely, at an ongoing cost to the customer. XO2 doesn't offer long warranties. The professional applicator sets the conditions, length and follow-up of their warranties.

What's the average coverage rate of Pro Seal Ultra?

• For porous surfaces: Professional application coverage is approximately 10 to 20 square metres per litre of Pro Seal Ultra for one coat on a porous surface. 2 to 3 coats are recommended and application rates vary depending on the porosity and texture of the surface being sealed. In some instances, coverage can be as low as 5 square metres per litre and as high as 30 square metres per litre per coat. Life expectancy and correct coverage are interdependent.
• For dense surfaces: Professional application coverage can range from 20 to 50 square metres per litre of Pro Seal Ultra for one coat. On dense surfaces, 2 thin coats are recommended and application rates vary depending on the porosity and texture of the surface being sealed.

How do I work out how much Pro Seal Ultra I need for a job?

1. Area to be sealed: _______m² (e.g. 100m²)
2. Number of coats: x _________ (e.g. x 3 coats)
3. Total area to be sealed (1.x2.): = ______m² (e.g. = 300m²)
4. Estimated average coverage rate: /______m² per litre (e.g. /15m² per litre)
5. Total amount of sealer needed (3.÷4.): = _____ litres (e.g. = 20 litres)

How do you prevent and remove sealer residues?

Difficult to remove residues from impregnating sealers are most common on dense surfaces such as polished porcelain or polished marble due to the overuse of product, using a product with a high level of active ingredients (that's a good thing!) or a failure to remove the sealer residue after 5 to 10 minutes of dwell time.

The best way to handle sealer residues is to prevent them. This comes down to paying a little extra attention during the sealer application. Whatever way the sealer is applied it is important that the sealer residues are dried and removed as much as possible after the second or last coat. Many people still apply penetrating sealers to the floor as if they were film-forming polishes (coatings). Applicators must understand that the product is a penetrating sealer and that the residues need to be removed from the surface after about 5 minutes of dwell time (absolute maximum: 10 minutes). Minor remaining residues can then be buffed off after 30 to 45 minutes. This buffing procedure is used by many professional sealer applicators on porcelain and polished stone because it leaves the surface clean, residue-free and with a rich gloss.

Removing Residues

If residues are allowed to dry on the floor and dry buffing does not remove them, they will generally respond to a cleaning treatment with Pro Seal Ultra or Methylated Spirits. The floor can be sprayed or hand-buffed with a moistened white towel with Pro Seal Ultra or Methylated Spirits.

Do I need to test first?

Yes. All surfaces are different, so test a small inconspicuous patch and allow 24 hours of curing time before assessing it. A test patch also doubles as a demonstration: pour water onto the sealed and unsealed sections to show the client how the surface repels liquids.

How long between coats, and when can people walk on it?

Allow 30 to 45 minutes between coats. Keep the surface free of traffic for 3 to 6 hours and completely dry for 12 hours after application. Full cure takes 48 to 72 hours.

What cleaner should I use on a floor sealed with Pro Seal Ultra?

Use Bobby Dazzler, Bonza or Too Easy for everyday cleaning. They're approved for use on surfaces sealed with Pro Seal Ultra. Avoid acid, solvent, alkaline and citrus-based cleaners at all times.

What if I have no choice but to use harsh chemicals?

Apply a top-up coat of sealer after cleaning with them.

Can I use Pro Seal Ultra on new floors?

New floor installations must be fully cured (minimum 48 hours). For newly poured concrete, allow 28 days before applying sealer.
