We no longer stock this product; without knowing the use of the floor, the closest alternative product we can offer is Sikafloor 3240.

Rust-Oleum 9400 Rust-O-Thane SL is a high build, self-levelling, solvent-free polyurethane for interior industrial, concrete and asphalt floors. Typical uses are interior process, manufacturing, packaging and warehousing areas subjected to heavy foot and pallet truck traffic and where a degree of flexing of the floor is expected.

This product offers excellent protection against high humidity and moisture, frequent spillage of chemicals, heavy abrasion, impact, and heavy pedestrian and vehicular traffic.

Surface Preparation
New concrete should cure and dry for at least 30 days prior to the application of the product. Remove oil, grease and all other surface contaminations by alkaline or high pressure (steam) cleaning. Concrete curing compounds should be removed completely. All laitance, loose or unsound concrete should be removed by vacuum-blasting or etching with Rust-Oleum Mathys 108 Surfa Etch Solution. Large surfaces should preferably be prepared by abrasive blasting (vacuum blasting). If this is impossible scrabbling or roughening of the surface is necessary - Profile maximum 0.5mm.

Defects in the concrete should be repaired with Rust-Oleum 5180 Epoxy Repair Mortar or Rust-Oleum 5412 Epoxy Filler. Previously coated surfaces must be in sound condition and a test-patch is recommended to check compatibility. The surface should be clean, dry and have a strength of minimum of 25 N/mm² before the coating can be applied.

Directions for Use
Add all of Hardener B to Base A. Mix with slow speed drill and helical spinner, taking care not to entrain air. It is advisable to pour mixed contents into a second container and re-mix to ensure the product is homogenous and no soft spots are seen in the applied coating.

• 4.9 parts of Base A are mixed with 1 part of Hardener B, by weight.
• 3.9 parts of Base A are mixed with 1 part of Hardener B, by volume.

The product is supplied in full units as A+B. Do not split the compounds/components as this may jeopardise the end result.

Pot-life: 45 minutes at 20°C (at higher temperatures the application time is shorter).

Application
Rust-Oleum 9400 Rust-O-Thane SL is applied with a rake and/or trowel and de-aeration roller. Use Rust-Oleum 5401 Epoxy Impregnation Primer or Rust-Oleum 5421 Epoxy Floor Primer Rapid on porous mineral substrates prior to application. Use Rust-Oleum B95SL Flexible Self Levelling Epoxy – diluted with 20% Rust-Oleum Thinner 641 on asphalt floors. On dense surfaces first apply a coat Rust-Oleum 3333 Super Adhesion Primer or Rust-Oleum 3366 Epoxy Powerfloat Floor Primer Rapid.

Clean-up: Use Rust-Oleum Thinner 160.

Application Conditions
The recommended substrate and environment temperature is 15 - 25°C, but no less than 10°C. The temperature of the substrate should exceed the “dew point” by 3°C during application and hardening. Temperatures should not fall below 5°C in the 24 hours after application.

Remarks

Do not cover or wash within the first 24 hours of curing. Chemical resistance: check our resistance chart. Some chemicals may cause discoloration. The product is not colour fast and may change colour over time (exhibits a yellowing effect). Colour change depends on the UV light and heat levels present and hence the rate of change cannot be predicted.
