Akemi Buff Knifegrade THIXO 1000 ml (Polyester Filler)
AKEMI® Marmorkitt 1000 THIXO is a professional, two-component (2K) polyester filler and adhesive built for the stone-fabrication trade. Based on an unsaturated polyester resin with mineral fillers, its knife-grade, thixotropic (“THIXO” = non-sag) consistency is creamy-soft, so it spreads and holds on horizontal and vertical surfaces without running — ideal for filling larger holes and voids (such as in travertine) and for bonding and laminating natural and engineered stone. The buff shade blends into beige and light-toned stone, and once cured the filler sands, drills, mills, and polishes cleanly for an invisible repair.
- Knife-grade & thixotropic — creamy-soft, non-sag body that stays put on vertical joints and fills without slumping
- Fast surface dry & rapid cure — hardens in roughly 15–30 minutes so work moves quickly
- Finishes beautifully — sands, bores, mills, and takes a very good polish
- Heat- and fluid-resistant — strong adhesion on stone even at elevated temperatures; resists water, petrol, and mineral oils
- Tintable with AKEMI® polyester colour pastes, colour concentrates, or Spectrum Pastes (up to 5%)

| Brand | Akemi |
| Manufacturer | AKEMI GmbH, Nuremberg, Germany |
| Product Type | Two-component (2K) polyester filler & knife-grade adhesive |
| Chemical Basis | Unsaturated polyester resin in styrene, with mineral fillers |
| Consistency | Knife-grade, thixotropic (non-sag) creamy paste |
| Color | Buff (beige) — Marmorkitt 1000 THIXO range also offered in white, black, and Jura/travertine stone shades |
| Hardener | Separate white BPO (dibenzoyl peroxide) cream hardener |
| Mixing Ratio | 1–4 g hardener per 100 g filler (approx. 2–3% typical) |
| Working / Pot Life | Approx. 3–10 min at 68°F (20°C), depending on hardener dose |
| Workable / Transportable After | A further approx. 10–20 min at 68°F (20°C) |
| Overall Hardening Time | Approx. 15–30 minutes (heat accelerates, cold delays) |
| Density | 1.70–1.75 g/cm³ (14.2–14.6 lb/gal) |
| Reaction Shrinkage | Approx. 2–3% — keep adhesive layers thin, under 0.08 in (2 mm) |
| Heat Resistance | Up to 158–176°F (70–80°C); briefly / at low load 212–230°F (100–110°C) |
| Minimum Application Temp. | Above 41°F (5°C) — below this, hardening is considerably delayed |
| Chemical Resistance | Water, petrol, and mineral oils |
| Tool Cleaner | AKEMI® Nitro-Dilution (uncured filler only) |
| Shelf Life | At least 12 months unopened, stored dry at 41–77°F (5–25°C) |
| Available Sizes | 150 mL · 1 L (1000 mL / 33.8 fl oz) |
- Very good workability thanks to a creamy-soft, thixotropic consistency — excellent on vertical surfaces
- Very good, rapid surface drying followed by trouble-free further processing
- Rapid hardening (approx. 15–30 minutes) keeps fabrication moving
- Sands, drills, and mills easily and takes a very good polish
- Very good adhesion on natural stone even at higher temperatures
- Resistant to water, petrol, and mineral oils once cured
- Fills larger holes and voids without running or sagging — well suited to travertine
- Colourable with AKEMI® polyester colour pastes, colour concentrates, or Spectrum Pastes (max. 5%), and thinnable with AKEMI® Marmorkitt 1000 Transparent extra-fluid
Used in stone-working shops for filling and bonding:
- Filling holes, pits, and voids in natural stone (e.g. travertine)
- Bonding and laminating natural and engineered/artificial stone
- Cementing large horizontal and — especially — vertical surfaces
- Modeling and rebuilding corners and edges
Please note: adhesion and strength on fresh, alkaline building materials (e.g. concrete) is only moderate, and bonds frequently exposed to moisture and frost are not permanently resistant.
Professional use only.
- Make sure the substrate is clean, completely dry, and slightly roughened.
- If desired, tint with AKEMI® polyester colour pastes, colour concentrates, or Spectrum Pastes — up to a maximum of 5%; the filler may be thinned in any ratio with AKEMI® Marmorkitt 1000 Transparent extra-fluid.
- Add 1–4 g of white BPO cream hardener per 100 g of filler (1 g of hardener corresponds to about 4–5 g squeezed from the tube). Use less hardener when filling large holes or modeling corners and edges.
- Mix both components thoroughly. The mixture stays workable for approx. 3–10 minutes at 68°F (20°C).
- After a further 10–20 minutes, the treated parts can be sanded, drilled, milled, or transported. Keep adhesive layers as thin as possible — under 0.08 in (2 mm).
- Heat accelerates and cold delays hardening. Clean tools with AKEMI® Nitro-Dilution before the filler cures.
- Keep the hardener dose in range: more than 4% reduces adhesion and can impair surface drying; less than 1% (or temperatures below 41°F / 5°C) considerably delays hardening.
- Because of reaction shrinkage (approx. 2–3%) and noticeable heat build-up during curing, keep adhesive layers thin (under 0.08 in / 2 mm).
- Bonds frequently exposed to moisture and frost are not permanently resistant.
- Cured filler tends to yellow over time.
- Cured filler cannot be removed with solvents — only mechanically or with high heat above 392°F (200°C).
- When used correctly and once fully hardened, the product is not harmful to health.
- Industrial chemical product — use only in well-ventilated areas and wear chemical-resistant gloves and eye protection. Always consult the AKEMI Safety Data Sheet (SDS) before use.
Industrial chemical product. Use only in well-ventilated areas. Wear chemical-resistant gloves and eye protection. Consult the AKEMI Safety Data Sheet (available from the manufacturer or stein.akemi.de) before use. Technical values are manufacturer figures at 68°F (20°C) and may vary with hardener dose and jobsite conditions.
