Pro Seal 896 – Commercial Cure Assist Sealing for External Concrete Areas

Exclusive to Water Based Sealers Pty Ltd

What is Cure-Assist Sealing?

Water Based Sealers Cure-Assist Sealing combines two very important processes into one easy application for external concrete works only. This same day of pour sealer application is not suitable for internal polished concrete surfaces, full cure time required. Sealing, grouting & densifying treatments for any form of polished concrete should be done by professional contractors only.

Curing Concrete

An essential ingredient in all concrete curing reactions is water. Without water, the curing reactions stop. The longer the water is retained in the slab, the more complete the curing and the stronger the concrete will be. A very slow drying slab will not only be stronger but will have fewer surface cracks, because as the water leaves the slab shrinks. If this process is fast the concrete has not developed enough strength yet to withstand the shrinkage and cracks develop.

Traditionally curing was accomplished by flooding, but in recent times the application of curing compounds is much more common. There are many different types but all of them need to be completely removed before a final sealant can be applied.

Sealing Concrete

A concrete seal is a physical barrier that protects and enhances the surface of the concrete. Most sealers require a slab to be completely dry before they can be applied. This means, in best practice, a slab cannot be sealed until at least 28 days after it is poured. There are some ‘same day’ sealers available, but these sacrifice long-term performance for moisture tolerance and are a temporary seal at best.

Water Based Sealers products are based on revolutionary technology that enables them to be applied to very wet surfaces. They use the water as a conduit to penetrate deep into the concrete to create a long-lasting matrix seal that cannot peel or flake.

This affinity for water allows WBS sealers to be applied to freshly poured slabs without compromising on the sealer longevity or performance.

Cure-Assist Sealing

Applying WBS sealers to a fresh slab will not just seal the surface it will also lock in the water needed for the slab to effectively cure. We call this Moisture Retention Technology (MRT). Same day lay and spray is not a suitable for internal burnished or polished concrete finishes.

Cure-Assist Sealing is an easy, time saving and cost-effective method of achieving super-strong concrete that is protected from stains from day one. It will minimize surface cracks, dusting concrete efflorescence and damage due to cleaning operations. This ensures the decorative concrete is kept off the defect list and has been used successfully in commercial applications throughout Australia for over 5 years.

Within the first 90 days, MRT Treated concrete will have a different visual appearance compared to unsealed concrete.

What to Expect:

  • MRT Treated concrete will look moisture patchy when it rains or is rinsed with water. This is a visual confirmation of MRT in progress. This effect is more noticeable on darker oxide coloured concrete but will stabilise itself with time.
  • This moisture patchiness will slowly subside and even out as both the concrete and the sealers cure together, multiple coats of sealer will increase the settling time (slower moisture loss) but will offer more benefits to the concrete in the long term.
  • During the first 20-30 days, the concrete and the sealers will cure in unison. Pro Polish 770 will Super-Plasticise the top layer of the concrete for increased strength, while the Pro Seal 896 will form a tight crosslinking acrylic seal to provide outstanding stain resistance.
  • The Surface can be driven on after 5 days.
  • Black tyre marks may still appear but they will not embed into the concrete surface and can be easily cleaned off or will dissipate by themselves with normal exposure to the elements.

Recommendations:

  • Re-Seal every 3-5 years for best results.
  • Allow 5 days curing time prior to vehicle traffic.
  • DO NOT High-Pressure Clean concrete over 3000 psi.
  • Clean with soap & water and medium-pressure rinsing.

Pro Seal 896 Mixing Instructions

1) Mix concentrated Pro-Seal 896 well before use

2) Mix ratio is 1 part Pro-Seal 896 to 4 parts water

3) Mix this solution well without aeration

4) Application rate is 5 m2 per litre

5) As soon as the concrete is hard enough to walk on (immediately after surface finishing, i.e. broom or steel finishing) apply the Hydro-Barrier (thin layer of water on the surface)

Product Application

6) Apply Pro-Seal 896 onto the wet surface at the specified application rate.

7) Allow laying undisturbed for a minimum of 5- 20 minutes depending on sun and wind conditions.

8) Using a medium/soft bristle broom lightly broom out any puddling that occurs in uneven sections of the slab

9) Allow drying clear before applying the second coat if required. The first coat will retard the penetration of the second coat and more product will stay on the surface to create an acrylic microfilm. This microfilm will increase the appearance and performance of the sealer.

10) Allow 24 hours curing for foot traffic 5 days for vehicle traffic.

Instructions for sealing Oxide Coloured Concrete New and Old

1) Sealing oxide coloured concrete is NOT the same day lay and spray process.

2) New oxide coloured concrete should stand for 48 to 72 hours depending on how dark or the quality of the oxide product used

3) Clean the surface of the concrete with water (do not use high-pressure cleaners on new concrete)

4) While the surface is wet, apply the first coat of Pro Polish 770 at 4:1, this is a colour stabilizer for sealing oxide concrete

5) The following day, lightly rinse the surface with water to make clean.

6) Apply Pro Seal 896 at 4:1 to the clean damp surface.

7) Be sure to wait around to make sure no puddles form, and if there is puddling, broom the puddles out to the drier areas of the surface until absorbed and dry.

ProSeal 896 Concrete Sealer Prevents Efflorescence

Another common issue for curing concrete is the development of efflorescence. Pro Seal 896 prevents efflorescence both during curing and throughout the life of the slab. Efflorescence is the result of liquid water migrating to the surface. As this water evaporates it leaves behind any salts that were dissolved in it. The moisture retention properties of the Pro Seal 896 significant reduce the transmission of water to the surface. Any moisture that gets through does so as a vapour, not a liquid, so it contains no salts. As such efflorescence ceases to be an issue.

*Important

ProSeal 896 Concrete Sealer Incompatible with Aliphatic Alcohols

Aliphatic Alcohol is not required when utilising the Pro Seal 896 ‘Same Day Lay and Spray’ process. Pro Seal 896 is chemically incompatible with aliphatic alcohol and the two cannot be used together. If aliphatic alcohol has been used inadvertently or its use is mandatory in the design specification, do not use Pro Seal 896 until curing is completed and all traces of the aliphatic alcohol are removed. Residuals will limit penetration of Pro Seal 896 into the concrete surface. Please contact us if you require further information.

New Oxide Coloured Concrete may have Surfactants in the mix can react with Pro Seal 896. Same day sealing process is not recommended, always allow 48 hours before sealing colour oxide treated newly laid concrete. Before you seal, rinse the colour concrete surface thoroughly with water before sealing with Pro Polish 770 (first coat) day 1 and final coat the next day with Pro Seal 896.
