Description

ProSeal 898 Gloss Concrete Sealer Concentrate Logo

 

Pro Seal 898 Gloss Concrete Sealer  is an eco friendly, water based, non-toxic, breathable, natural stone and concrete sealer. The nano polymers in Pro Seal 898 penetrate deep into porous materials. As the product cures these polymers crosslink to form a structured, 3 dimensional matrix which fills the pores in the material being sealed.  Not only does this seal the surface but it also consolidates and strengthens it. Additional coats will bond more polymer units to this matrix. This produces a glossy, hard wearing, protective wear layer above the surface.

Pro Seal’s nano ploymers ensure it can penetrate into materials with very fine pore structures. Pro Seal 898 is ideal for dense concrete, granite, marble and other natural stone surfaces. It’s tight, chemical resistant matrix provides strength, durability and excellent stain resistance. These attributes make it the perfect solution for commercial, workshop and warehouse floors.  It is a pure, high cross-linking matrix sealer, developed and made right here in Australia by Water Based Sealers. for Australian conditions.

The Problem with Traditional Gloss Concrete Sealers

Common acrylic sealers consist of large individual polymer chains that are thousands of times larger than ProSeal 898. They are effectively a thick mess of long polymer strands. A good visualisation is to think of a bowl of wet spaghetti. As these sealers dry, the solvent evaporates out and these polymer strands shrink back, tangling themselves into a knotted mat. Since the polymers are tied up in random ways there can be high variability in how the film performs under stress. Failures can occur as a result of high wear, thermal expansion and contraction or exposure to harsh weather conditions.

The individual polymers in most topical sealers are far too large to get into most of the pores in the concrete. So the whole film is effectively just sitting on the surface. These films rely on a fairly weak adhesion to keep them stuck to the surface. To get better adhesion industry experts recommend acid etching prior to using topical sealers. An acid etch produces a rougher surface and there is more for the film to “hold on to”.  For this reason, traditional film forming sealers are far more prone to delamination and failure than penetrating sealers.

Other common isues with traditional topical sealers:

  • Polymers will swell and re-emulsify in the presence of their solvent (either oil or water based). If you spill solvent on them they will re-dissolve. An example is oil or diesel drips onto a driveway sealed with a solvent based acrylic will often just ‘melt’ into the seal.
  • They are not breathable. Any moisture that comes up under the seal will get trapped. This will make the sealer look hazy and with time will lead to delamination.
  • Poor or inconsistent levels of flexibility may lead to crazing, cracking and delamination.

Pro Seal is a Better Way to Seal Concrete

Pro Seal is completely different approach to sealing. It does the bulk of it’s work inside the concrete, not on top. It’s polymer chains are tiny. In Pro Seal 898 Gloss Concrete Sealer the individual polymer chains are just a few nano-meters in length. They penetrate deep into the substrate and bond together to form an interlocking, 3 dimensional matrix from the inside out. This matrix is permanent and serves to strengthen and protect the materials sealed.

Since it is anchored deep within the pores of the sealed material, the Pro Seal matrix has absolute adhesion. It is completely embedded in the surface and therefore cannot be peeled off. The top of the matrix sits above the surface and provides a wear layer. Appling a maintenance coat every few years will bond to the matrix in the substrate and replenish the wear layer, delivering the ultimate in ongoing protection.

Pro Seal 898 Gloss Concrete Sealer has the smallest polymer size in the Pro Seal range. So it can be used for extremely dense materials with very fine pore structures like densified concrete, granite and even uncrystalised marble.

ProSeal does not re-emulsify in the presence of water or oils and is resistant to most chemicals. As such it can be used with confidence for most applications, both indoors and out.

The ProSeal matrix structure is such that water molecules can diffuse through it. This means that any moisture that gets into the substrate can slowly escape without damaging the seal. This is important for most external applications, and is essential in areas with porr drainage and significant rising damp.

Gloss Levels

How glossy something appears is a function of how much light is reflecting off a surface and into your eye. Textured surfaces reflect light at varying angles. The light is scattered, so less light actually reaches your eye. To increase the gloss on a highly textured surface you need to artificially smoothen the surface. The most common means to achieve this is by mechanically polishing or by applying a high build self leveling coating.

Gloss Concrete Sealer Light Scatter Diagram

Being a true nano sealer, Pro Seal 898 Gloss Concrete Sealer builds a very thin, yet tough surface layer. Although the sealer itself has a very high gloss level it won’t produce a thick film and won’t artificially fill or smooth out highly textured finishes, like a self leveling product will. This means that the gloss level that will be achieved may vary depending on the texture of the surface to which it is applied. On smooth surfaces Pro Seal 898 will be very shiny and it can be buffed to produce even higher gloss levels if desired.

Application Methods

Apply as a 2 coat stand alone sealing system on natural stone or polished concrete. Or use as a final coat over Pro Seal 896 or Pro Seal 770 on more porous surfaces. For more porous surfaces, like normal concrete, Pro Seal 896 Satin Concrete Sealer may be more efficient at filling the larger pores. Pro Seal 896 is also recommended where more grip is required or if you prefer a lower gloss finish.

Uses

Pro-Seal 898 is used with confidence to seal and provide stain protection for all types of natural stone, including benchtops and tables.

Pro Seal 898 is also used as a final gloss coat together with another WBS product, usually Pro Polish 770 or Pro Seal 896.

Pro Seal 898:

  • is a penetrating sealer
  • provides superior stain-protection
  • is a great option to seal natural stone bench tops used outdoor kitchens as it is UV Stable, Non-Toxic and won’t peel, blister or turn yellow.
  • is an excellent top coat option for driveways, alfresco’s, around pools or wherever a higher gloss finish is required.

Application

Pro Seal 898 comes in a highly concentrated form that requires dilution with water prior to application.  Completely saturate all substrates prior to application to ensure the best possible penetration and performance.

Suggested dilution rate:  1:3 (1 part product 3 parts water)

Dense Natural Stone and Polished Concrete:
Apply Pro Seal 898 as a fine mist spray and massage in thoroughly with a micro-fibre cloth.  Ensure any access sealer is wiped off the surface.  Failure to wipe off excess may result in an uneven finish.

Exposed Aggregate & Other Porous Surfaces:
Apply diluted Pro Seal 898 as flood coats to the point of satuaration with either a watering can, garden sprayer or commercial spray unit.

Use a soft bristle broom to sweep out any pools that develop. The sealer can be walked over without concern during the curing process.

A minimum of 2 coats are recommended. Additional coats should be applied as required to acheive a water tight seal.

While Pro-Seal 898 will remain in the substrate and provide protection for 15+ years it is recommended that a re-coat be applied to the surface once every 3 years to maintain best appearance. This is particularly relevant for high use areas. ProSeal does not need to be stripped off prior to reapplication. Polymer in the new coat will bond to the existing matrix in the substrate.

Safety

  • Keep out of reach of children.
  • Wash up any spills by flushing with water.
  • It is best practice to clean spills as soon as practical. Most household cleaners can be used on Pro-Seal 898, however use of harsh chemicals may damage or reduce the working life of the sealer.
  • Avoid contact with eyes and skin
  • Keep product out of direct sunlight
  • Store in cool dry area
  • Classified as Non-Hazardous Material

    I’m glad I spoke to you about prep and application. Friend did a good gurney job and while it was wet…applied the first coat with the soft broom. Dried so perfectly I was reluctant to put on a 2nd coat. I did a day later – as you recommended. Drove car carefully across after 1 day – no problem.
