Exterior Painting for London Victorian Terraces: Masonry, Timber, and Metalwork

LONDON VICTORIAN TERRACES TYPICALLY HAVE ONE OF THREE MASONRY FACADE CONDITIONS: 1. UNPAINTED LONDON STOCK BRICK (THE MAJORITY — NOT PAINTED, NOT RENDERED) 2. LIME-RENDERED OR STUCCO FINISH (PARTICULARLY REGENCY AND EARLY VICTORIAN — ITALIANATE STUCCO DETAILING AROUND WINDOWS, PILASTERS, CORNICE) 3. LATER PAINTED RENDER (OFTEN PAINTED CEMENT RENDER APPLIED IN THE 20TH CENTURY)

STUCCO AND LIME RENDER (ORIGINAL FINISH): ORIGINAL VICTORIAN STUCCO IS LIME PUTTY AND FINE AGGREGATE — EXTREMELY DURABLE WHEN UNPAINTED, BUT ONCE PAINTED REQUIRES CONTINUED MAINTENANCE. THE CORRECT PAINT SYSTEM FOR LIME STUCCO: - PRIMER: SANDTEX STABILISING PRIMER (IF FRIABLE) OR DULUX WEATHERSHIELD MASONRY PRIMER (ALKALI-RESISTANT PRIMER ON NEW RENDER) - TOPCOAT: SANDTEX ULTRA SMOOTH MASONRY PAINT (SMOOTH FINISH; 10-YEAR WARRANTY; BREATHABLE ENOUGH FOR LIME RENDER); OR DULUX WEATHERSHIELD SMOOTH (SIMILAR PERFORMANCE); OR, FOR A MORE TRADITIONAL APPEARANCE ON HISTORIC BUILDINGS: KEIM MINERAL PAINT (SOLDALIT OR GRANITAL) — A SILICATE MINERAL PAINT THAT FUSES PERMANENTLY WITH THE MASONRY SUBSTRATE (NO FILM-FORMING — CANNOT PEEL OR BLISTER).

KEIM MINERAL PAINTS: KEIM IS THE GOLD-STANDARD EXTERIOR MASONRY COATING FOR LONDON PERIOD BUILDINGS: - KEIM SOLDALIT (SMOOTH SILICATE PAINT): PERMANENTLY BONDS WITH MINERAL SURFACES (LIME RENDER, BRICK, STONE); EXTREMELY BREATHABLE (WATER VAPOUR TRANSMISSION MUCH HIGHER THAN ACRYLIC MASONRY PAINTS); NON-FILM-FORMING (CANNOT PEEL); 25+ YEAR LIFE. COLOUR RANGE: 350+ COLOURS INCLUDING PERIOD-APPROPRIATE STONE/BUFF/WHITE/GREY TONES. - KEIM GRANITAL (TEXTURED SILICATE PAINT): FINE AGGREGATE TEXTURE; USEFUL FOR DISGUISING SURFACE IMPERFECTIONS. - COST: KEIM IS 3-5X THE PRICE OF STANDARD MASONRY PAINT — BUT LIFE CYCLE COST IS SIGNIFICANTLY LOWER.

SURFACE PREPARATION FOR MASONRY: - JET WASH ALL SURFACES AT LOW PRESSURE (200-400 PSI MAX — DO NOT USE HIGH PRESSURE ON SOFT BRICK OR LIME RENDER) - TREAT ALGAE/LICHEN WITH ALGAE BUSTER OR OWATROL AQUASTOP - RECLEAN AND REPAIR CRACKS (LIME PUTTY CAULK FOR FINE CRACKS; NHL 3.5 LIME MORTAR FOR LARGER CRACKS IN RENDER) - MASK OFF AND PROTECT WINDOWS, DOORS, AND WOODWORK BEFORE MASONRY PAINTING

EXTERIOR TIMBER REQUIRES A DIFFERENT SYSTEM FROM MASONRY — THE FLEXIBILITY AND ADHESION REQUIREMENTS ARE DIFFERENT BECAUSE TIMBER MOVES WITH MOISTURE AND TEMPERATURE.

SURFACE PREPARATION (CRITICAL): THE MOST IMPORTANT FACTOR IN EXTERIOR TIMBER PAINT LIFE IS PREPARATION: - STRIP ALL LOOSE, CRACKING, OR FLAKING PAINT TO BARE WOOD (HEAT GUN — FESTOOL RAS 115.04 E; CHEMICAL STRIPPER — NITROMORS ALL PURPOSE PAINT REMOVER; OR MECHANICAL SANDING — ORBITAL SANDER WITH 60-80 GRIT). - TREAT BARE WOOD WITH OWATROL OIL (PENETRATING RUST AND ROT INHIBITOR FOR BARE WOOD — STABILISES SOFT OR CHALKY WOOD AND IMPROVES ADHESION). - FILL CRACKS AND OPEN JOINTS WITH EXTERIOR TWO-PART FLEXIBLE FILLER (TOUPRET EXTERIOR FIBRELITE — WHITE, FLEXIBLE WHEN DRY, PAINTABLE). - PRIME BARE WOOD WITH JOHNSTONE\'S ACRYLIC PRIMER UNDERCOAT (WATER-BASED; FAST DRY; LOW ODOUR) OR DULUX TRADE QUICK DRY PRIMER UNDERCOAT.

TOPCOAT SYSTEMS FOR EXTERIOR TIMBER: - JOHNSTONE\'S EXTERIOR SATIN GLOSS (SOLVENT-BASED SATIN): THE TRADITIONAL CHOICE FOR LONDON PERIOD PROPERTY EXTERIOR JOINERY. SOLVENT-BASED (ALKYD) SYSTEMS BUILD A HARDER FILM THAN WATER-BASED; SELF-LEVELLING; LONG OPEN TIME. COLOUR: OFTEN BRILLIANT WHITE OR OFF-WHITE (F+B POINTING 2003, LITTLE GREENE PEARL COLOUR). - DULUX TRADE WEATHERSHIELD EXTERIOR GLOSS (SOLVENT-BASED): SIMILAR TO JOHNSTONE\'S; WIDELY AVAILABLE THROUGH DECORATORS MERCHANTS. - TEKNOS AQUATEX (WATER-BASED EXTERIOR WOOD PAINT): WATER-BASED BUT HIGH-PERFORMANCE FILM; LOWER ODOUR; QUICK-DRY; USED BY PROFESSIONAL DECORATORS ON LONDON PERIOD PROPERTIES INCREASINGLY FROM 2020+. MINIMUM 2 COATS TOPCOAT ON PREPARED BARE WOOD (AFTER PRIMER UNDERCOAT). TOTAL PAINT SYSTEM: OWATROL OIL PENETRANT + PRIMER UNDERCOAT + 2 TOPCOATS = TYPICALLY 5-8 YEAR LIFE ON LONDON SOUTH-FACING FACADES.

FRONT DOOR PAINTING: THE FRONT DOOR IS THE MOST VISIBLE AND MOST OFTEN PAINTED ELEMENT OF A LONDON VICTORIAN TERRACE. POPULAR DOOR COLOURS IN LONDON 2024-2026: - FARROW+BALL RAILINGS (NO. 31): THE MOST POPULAR LONDON DOOR COLOUR — DEEP NAVY/CHARCOAL WITH BLUE UNDERTONE. - FARROW+BALL ELEPHANT\'S BREATH (NO. 229): WARM GREY — VERY POPULAR IN CONSERVATION AREAS. - LITTLE GREENE INTELLIGENT GLOSS: HARD FILM, EXCELLENT DURABILITY — BETTER THAN F+B FOR HIGH-USE FRONT DOORS. - ZINSSER BULLSEYE 123 PRIMER: THE BEST ADHESION PRIMER FOR FRONT DOORS (WATER-BASED; STAIN-BLOCKING; BONDS WELL TO EXISTING GLOSS WITHOUT SANDING THROUGH).

METAL ELEMENTS ON A LONDON VICTORIAN TERRACE INCLUDE: CAST IRON OR MILD STEEL RAILINGS; CAST IRON GUTTERS AND HOPPER HEADS; CAST IRON OR STEEL DRAIN PIPES; STEEL LINTELS; AND DECORATIVE IRONWORK.

CAST IRON AND STEEL PREPARATION: 1. WIRE BRUSH ALL RUST AND LOOSE PAINT (WIRE BRUSH ATTACHMENT ON ANGLE GRINDER — 4.5 INCH WIRE CUP BRUSH FOR FLAT RAILINGS; HAND WIRE BRUSH FOR DETAILED IRONWORK) 2. APPLY RUSTINS RUST REMOVER (PHOSPHORIC ACID GEL — CONVERTS RUST TO IRON PHOSPHATE; LEAVES A DARK GREY PRIMER-RECEPTIVE SURFACE) 3. PRIME WITH HAMMERITE DIRECT TO RUST METAL PAINT (NO SEPARATE PRIMER NEEDED — BONDS DIRECT TO RUST-TREATED SURFACE); OR WITH ZINSSER RUST-OLEUM PRIMER (SOLVENT-BASED ALKYD).

TOPCOAT FOR METALWORK: - HAMMERITE SMOOTH GLOSS (SOLVENT-BASED, DIRECT TO METAL): THE STANDARD CHOICE FOR LONDON PERIOD PROPERTY METALWORK PAINTING. COLOUR: BLACK (RAL 9005 EQUIVALENT). SELF-PRIMING ON RUST-TREATED SURFACES. LIFE: 5-8 YEARS IN LONDON CLIMATE. - RUST-OLEUM STOPS RUST GLOSS: ALTERNATIVE TO HAMMERITE; SIMILAR PERFORMANCE. - TWO-PACK EPOXY POLYURETHANE (INTERNATIONAL JOTAMASTIC 80 OR SIMILAR): USED FOR SEVERE RUST CONDITIONS OR WHERE MAXIMUM LIFE IS REQUIRED. PROFESSIONAL APPLICATION; NOT DIY-APPROPRIATE.

CAST IRON GUTTERS AND HOPPER HEADS: CAST IRON GUTTERS MUST BE PAINTED ON THE INSIDE (TROUGH FACE) AS WELL AS THE OUTSIDE — THE INSIDE IS WHERE WATER SITS AND WHERE RUST ORIGINATES. USE HAMMERITE BLACK SMOOTH INSIDE AND OUTSIDE. CLEAN DOWNPIPE JOINTS AND CHECK THAT SEAL IS INTACT — LEAKING JOINTS CAN CAUSE DAMP TO PENETRATE BRICK AT WALL HEAD.
