Drymix — Crepifix 800 — Premium Fine Rendering Mortar

Drymix Crepifix 800 is a premium cement and fine basalt sand rendering mortar for smooth finishes on block or cellular surfaces, interior and exterior. With compressive strength ≥ 20 MPa and flexural strength ≥ 4.0 MPa, it is the highest-performance render in the Crepifix range. Extended open time of 50–60 minutes. Compliant with EN 1015 / EN 12004, ISO 9001 certified.

Applications:
– Smooth finish rendering on block or cellular surfaces
– Interior and exterior
– Use Primefix Plus on smooth concrete surfaces

Key advantages vs Crepifix 450:
– Higher compressive strength: ≥ 20 MPa vs 15 MPa
– Higher flexural strength: ≥ 4.0 MPa vs 3.0 MPa
– Longer open time: 50–60 min vs 45–50 min
– Suitable for block AND cellular surfaces

Application:
Moisten surface with masonry brush. Add bag to 5.0–5.6 L water, mix 2–3 min, rest then apply max 10 mm. If thickness > 10 mm, comb first coat and apply final coat after 24 hours. Use Primefix Plus on smooth concrete surfaces. Start early morning. Never mix on the floor. Cure daily for 3 days.

Precautions:
– Do not apply below 5°C or above 35°C
– Avoid rain or dripping surfaces
– Protect from wind and direct sunlight
– Wear gloves and goggles during handling
