Set up for a 36 × 28 ft two-storey house. Add gables separately (width × gable height ÷ 2 for each). Rough surfaces like stucco, brick and block soak up more paint, so round up. In Flat, Low Lustre and Satin, the calculator switches to 18.9 L pails when they work out cheaper.

Painting vinyl siding? Choose a colour no darker than the original with a Light Reflective Value (LRV) of 57 or higher, or one from Benjamin Moore's Colours for Vinyl palette. Darker colours absorb heat and can warp vinyl. Not sure? Ask us before you order. Screen colours are a guide, so try a colour sample on the building first.

FAQ
Questions, answered.
What is Ultra Spec EXT?
Benjamin Moore's professional exterior paint, made for painting contractors, property managers and facility managers. It's a 100% acrylic paint that resists peeling, cracking and blistering, goes on down to 4.4 °C, and leaves a mildew-resistant coating, at a lower price than Benjamin Moore's premium exterior lines.
Ultra Spec EXT, Regal Select Exterior or Aura Exterior?
Ultra Spec EXT is the contractor choice: reliable, durable and economical, with pails in Flat, Low Lustre and Satin for big jobs. Regal Select Exterior is a premium high-build paint. Aura Exterior is Benjamin Moore's best, with Colour Lock fade resistance and application down to 1.7 °C.
How much do I need?
A 3.79 L can covers 350–450 sq ft per coat, and an 18.9 L pail about 1,750–2,250 sq ft. For 1,500 sq ft of siding, two coats take about 7 to 9 cans, or two pails. Use the paint calculator above for your house.
Which finish should I choose?
Flat or Low Lustre for siding, stucco and masonry. Low Lustre is easier to clean than flat. Satin or Soft Gloss for trim, shutters, railings and doors. Flat, Low Lustre and Satin come in 3.79 L and 18.9 L; Soft Gloss in 3.79 L.
How cold can it be when I paint?
Air and surface must be at least 4.4 °C (40 °F), and no more than 37.7 °C (100 °F). Cool, humid weather slows drying, so start after the morning dew is gone and finish early enough for it to dry before evening.
Do I need a primer?
It depends on the surface. Prime bare wood, hardboard and pitted vinyl with Fresh Start High-Hiding All Purpose Primer, which also works on cedar and other bleeding woods. Poured concrete and fibre cement are self-priming. Bare steel needs a metal primer. On a repaint, prime bare spots only. Ask us if you're not sure.
Can I paint vinyl siding?
Yes, but don't use a colour darker than the original or with an LRV below 57, unless it's in Benjamin Moore's Colours for Vinyl palette and meets the siding maker's guidelines. Darker colours absorb heat and can warp vinyl.
Can I thin it or spray it?
Spray it with an airless sprayer at 1,500–2,500 PSI (.013–.017 tip for Flat and Low Lustre, .011–.015 for Satin and Soft Gloss). If needed, thin with up to 236 mL of water or Paint Extender K518 per 3.79 L.
Is there a warranty?
Yes, a limited lifetime warranty for the original residential purchaser. It covers blistering, peeling and wearing through to the old paint when it's applied to properly prepared and primed surfaces as the label directs. It doesn't cover labour and isn't transferable.
Colours, sizes and shipping?
Any Benjamin Moore colour (Color Stories colours aren't available in exterior paint), and we can match other brands. Tinted paint is made to order, so it's final sale. We ship across Canada, free on most orders over $249, or pick up free in Mississauga.
