From the FORSPEC data sheet, TDS-CRYSTALBOND · Revision 2 · 22 August 2026. Times are at 25°C and 50% relative humidity unless the data sheet says otherwise. Typical = FORSPEC’s own typical value, not a laboratory-certified one.
Where ACTFLEX CRYSTAL BOND is used
Use it for
- Clear epoxy floor coatings and sealers over decorative concrete
- Decorative, pigmented and metallic epoxy flooring
- Terrazzo and quartz flooring binder
- Epoxy screeds and repair mortars
- Countertops and architectural surfaces
- Casting, art resin and encapsulation works
Know before you start
- Not a waterproofing membrane: use the FORSPEC membrane ranges
- Not over bituminous or flexible membranes, or substrates over 4% moisture
- Apply only at 10–35°C and below 80% RH, not in direct sunlight
- May amber under prolonged UV: ask FORSPEC for a UV-stable topcoat
How to apply ACTFLEX CRYSTAL BOND
- 01
Prepare
Concrete cured 28 days, 25 MPa minimum, diamond ground or shot blasted to CSP 2–4 and vacuumed. Moisture 4% or less, surface at least 3°C above dew point.
- 02
Prime
Self-priming. Apply the mixed resin neat by squeegee and back-roll at 150–250 microns DFT. No pigments, fillers or aggregates in the primer coat.
- 03
Mix
Condition to 18–30°C. Mix 3 parts A to 1 part B by volume at 300–400 RPM for 3 to 4 minutes, decant and re-mix 30 to 60 seconds. Full kits only, no dilution.
- 04
Apply
Coat at 0.8–1.2 mm over the tacky primer (8 to 12 hours, within 24). Decorative pours 1–2 mm, deep pours 2–4 mm. Epoxy screed up to 15 mm per layer.
- 05
Finish
For anti-slip, broadcast ACTFLEX ANTISLIP aggregate into the wet coat to 70–90% refusal, vacuum after 12 to 24 hours and lock in with a coat. Add a clear coat for maximum gloss.
- 06
Cure
Protect from dust, moisture, foot traffic and vibration for 24 hours. No chemical spill or immersion before full cure at 7 days.

ACTFLEX CRYSTAL BOND questions
Is ACTFLEX CRYSTAL BOND a waterproofing membrane?
No. It is a clear epoxy binder and coating. For waterproofing, use the FORSPEC liquid membrane range or sheet membrane range.
Do I need a separate primer?
No. It is self-priming. The first coat, applied neat at 150–250 microns DFT, seals the prepared substrate. Apply the next coat while it is tacky, typically 8 to 12 hours, and within 24 hours.
How much do I need?
A 30 L kit covers about 30 m² at 1.0 mm DFT in theory, before wastage. As a primer at 150–250 microns it covers 120 to 200 m². Porous or textured surfaces use more.
What is the mix ratio?
3 parts Part A to 1 part Part B by volume. Mix 3 to 4 minutes, decant and re-mix 30 to 60 seconds. Mix full kits only and do not alter the ratio or split kits.
How thick can I pour it?
Decorative and metallic pours go 1–2 mm, up to 4 mm maximum per layer in deep-pour work. Epoxy screeds go up to 15 mm per layer.
Can it be used outside in the sun?
Slight colour variation or ambering may occur under prolonged UV. For exposed work, consult FORSPEC for an approved UV-stable topcoat.
