For brush/roller use apply neat or slightly thinned; for spray application you may dilute up to 5–10% with clean water if necessary.
Touch dry is typically 30–60 minutes; allow 2–4 hours before applying plaster/render (depending on temperature & humidity).
Approx. 72–96 m² (based on 6–8 m²/kg). Actual coverage varies with surface porosity and application method.
Yes — when applied correctly and protected from rain until fully dry. Avoid application in freezing or rainy conditions.
Yes — it is a primer to improve adhesion; use a suitable decorative topcoat after plaster/render and curing.
Apply between 5°C and 35°C. Do not apply on frozen substrates or if rain/frost is expected.
