Rust-Oleum 4900 Polycoat 2K is a clear, water-based, 2-component polyurethane topcoat for use on wood, concrete and pre-painted surfaces, also serves as an anti-graffiti coating.

Recommended Uses

  • Clear varnish for parquet to protect against stains and scratches
  • Clear sealer for concrete to decrease dusting and increase cleanability
  • As an anti-graffiti coating
  • As a topcoat on previously painted surfaces to provide extra protection and/or change gloss level

  • Available in matt or gloss
  • Very abrasion resistant
  • Does not yellow; ideal for interior and exterior
  • Resists boiling water, alcohol, coffee, red wine, dilute acid and alkalis
  • Anti-Graffiti; easy to clean with Rust-Oleum GraffitiShield Cleaner

Surface Preparation

Ensure surface to be varnished is clean, dry, sound and free from wax, oil or any other contamination. If wax has been used clean the surface thoroughly with white spirit prior to sanding. Bare wood should be sanded to a smooth surface, always working with the grain. Sound previously varnished surfaces should be lightly sanded to provide a key. New concrete must be at least 6 months old prior to varnishing. Concrete must be clean, dry and free from any surface laitance (a weak dusty layer on new concrete) and any other surface contaminants such as oils, grease, dirt etc. prior to applying the varnish. Not suitable for direct use on power floated concrete.

Directions for Use

Base and activator are supplied in correct proportions. First stir the base component, then add activator gradually to the base, and mix thoroughly. DO NOT MIX PART UNITS. Wait 5 minutes after mixing. Do not store mixed product (residue) in a closed can. Badly activated or incorrectly mixed materials will affect performance and may cause early failure or discolouration. When used outdoors on top of pre-painted surfaces: If the old paint is not UV-resitant, the use of Multi-surface PU Heavy-Duty Varnish is not recommended.

Application

(Brush) - Apply evenly using light strokes following the grain of the wood. For best results 3 coats are recommended on new wood/concrete (dilute 1st coat with 10% water) and 2 coats on previously varnished surfaces.

(Roller) - Use a short nap mohair roller. For best results 3 coats are recommended on new wood/concrete (dilute 1st coat with 10% water) and 2 coats on previously varnished surfaces.

Notes

  • Not suitable for use on plastic type materials, e.g. imitation wood.
  • Do not wash the varnished surface for at least 3 days after application. If water is spilled on it during this period gently wipe off with a soft dry cloth.
  • Taber abrasion: weight loss CS17 / 1000 cycles: 17 mg
  • Resist stains of: Alcohol (40%), Ammonia, Fatty acids, Coffee, Red Wine, Water, diluted acids & alkalis.

Question

Rust is coming through concrete render where the angle bead is. What can I coat it with to stop the rust coming through before I sandtex it ?

Stephen george from Lowestoft (England ) - 27/07/17

Answer

Zinsser Cover Stain has been used in this situation to block the rust stains however there is no guarantee how long it will hold the stains back. As soon as any trace of moisture gets into the metal beading the rusting process will start again and stains are likely to bleed through once more. It would not be possible to say how long the primer would hold the staining back.

The render surfaces must be completely dry before applying the primer.

Applying 2 coats of the Cover Stain will give a little more protection and hold back the staining for longer than 1 coat.

The Cover Stain can be overcoated with a standard masonry type coating.

You could apply Zinsser AllCoat Exterior or Zinsser Perma-White Exterior over the Cover Stain primer. These products will reduce water ingress and hopefully prevent stains from reappearing for longer.

Note that the only 100% effective way to solve the problem would be to remove the affected angle beading and replace with new stainless steel or plastic beading.
