Description
What Is Agar STR‑36?
Agar STR-36 is a super-concentrated floor stripper with a powerful formula for ripping through old films and build-ups of hardened floor sealer, allowing all traces to be rinsed away. It is ideal for stripping semi-permanent sealer basecoats that resist normal strippers, as well as thick coatings of polish and edge build-ups.
Key Benefits of Agar STR-36
- Powerful stripping action, even on stubborn coatings
- Rips through old polish, heavy build-ups and semi-permanent sealers
- Thoroughly removes sealers in one application, minimising re-stripping
- Works best in cold water
- No ammonia smell
- Contains no caustic powders
- Low foaming, suitable for auto-scrubbers and mopping
- Leaves the floor ready for recoating
How Does Agar STR-36 Work?
Agar STR-36 rapidly breaks down and penetrates acrylic sealer, polish and wax films, including well-cured, aged, thick films and edge build-up, reducing the amount of machine scrubbing needed to get back to a clean floor.
Dilution Rates for Agar STR-36
Agar STR-36 is diluted according to the job at hand. Always use cold water for best results.
| Job | Dilution Ratio |
| Heavy build-ups | 1 part STR-36 to 4 parts cold water |
| Normal stripping | 1 part STR-36 to 8 parts cold water |
| Linoleum and timber | 1 part STR-36 to 20 parts cold water (minimum dilution) |
How to Apply Agar STR-36
Mop the diluted STR-36 solution over the sealer and allow 5-10 minutes for it to activate, keeping the floor wet with solution throughout (add more solution if it starts to dry out). Avoid splashing onto painted surfaces, timber or carpet. Scrub with a black or emerald pad on a slow-speed scrubbing machine, then mop up or wet-vacuum the resulting slurry. Rinse the floor three times with clean water; on porous floors, adding vinegar or Agar Neutralizer to the middle rinse is recommended to help neutralise any residual alkalinity.
