Exterior Wood
Cedar Shingle Facade with Natural Wood Oil
in Chennai, Tamil Nadu
Cedar shingle cladding on a Chennai residence — sealed with LEINOS Wood Primer 150 + Premium Wood Varnish 260. Open-pore, vapour-permeable protection through Tamil Nadu's monsoon cycle.

Context
The brief, and the surface.
A three-storey residence in Chennai, clad entirely in cedar shingles on a stone foundation. The exterior team needed a protection system that would survive Tamil Nadu's monsoon-cycle UV and humidity without darkening the cedar's natural tone or forming a film that could crack with seasonal movement. LEINOS Wood Primer 150 went down first on the absorbent timber; Premium Wood Varnish 260 followed in two open-pore coats, applied wet-on-wet per TDS protocol.
Working top-down, course by course, the team brushed Wood Primer 150 thinly enough to soak in within 20 minutes — no puddles on the flatter shingle faces, no streaking on the upturned course edges. Wood Varnish 260 followed at 16-hour intervals; the second coat built body without filling the grain.

Outcome
The result on site.
Across the entire cedar shingle facade, the Wood Primer 150 + Wood Varnish 260 system delivers a uniform golden-brown finish with visible water beading after a complete Tamil Nadu monsoon cycle.
The facade reads as a uniform warm golden-brown — the cedar's own colour still showing through, the open-pore varnish at a low glancing-angle sheen rather than a coating. After a full monsoon cycle, no chalking, no peeling, water beading on shingle faces and clean runoff at course edges.
Results vary by surface condition, climate exposure, application method, and ongoing maintenance.
