The finished wood things we have outside aren’t so fortunate. They’re exposed to the extremes of solar radiation from the sunlight… wetness in the forms of dew, rain, and snow…. high temperatures… freezing cold… fungal strikes… and sometimes foot traffic. Great exterior completes protect the wood from these conditions that are brutal, but will surely fail unless they're renewed on a scheduled basis. Maintenance is a must for outdoor wood finishes.
Choosing an Exterior Wood Finish There really are an assortment of exterior wood finishes with distinct features and properties. To pick the one that is best, you will need to fit the product with the job and make some decisions as well. All these are the crucial factors and concerns to pick the very best finish;
⦁ Function – Which finish is the most suitable choice for the project you are taking care of? For example, the finish you are using in your deck is not necessarily the best option for your new solid mahogany entrance door.
⦁ Life Cycle/Care – some finishes continue more than many others, but none last forever. How frequently have you been ready to clean, scrape, and/or sand and recoat the finish (i.e., weeks, months, or years) and how easy do you need the care and repair process to be?
⦁ Look – should the finish be clear and bring out the beauty and depth of the wood, lightly colored and semi transparent, opaque like paint, glossy (shiny), matte (dull), or seem “natural” – virtually invisible so that it’s not evident the wood has a finish?
⦁ Program – Given a choice, should the finish be relatively easy to apply or are you ready for a product that needs more work and advanced skills?
⦁ Cost – How important is the price tag?
Sadly, no finish scores well in all categories – you must choose a product that fits you as well as your project the very best. There’s give and take in the selection process – for instance, the finishes which are most easy to implement and keep don’t continue as long as the ones and also others that last longest are more work and more expensive. The one thing they all have in common is that they have to be recoated to maintain their protective qualities.Is a Finish Really Necessary? In the event you like the look of weathered wood that is silvery grey, you might be contemplating leaving your job bare and averting the full time plus expense associated with maintaining and using a finish. The climate is just right and in the event the wood is naturally resistant to decay, there’s the weathered appearance will be developed by a chance in time. There’s a better chance the wood turn green and black, grow mildew, and will get filthy.
Weathering and Decay In the outdoors, the forces of weathering and decay destroy bare wood. Weathering alone is a slow, purposeful process. Exposure to water and sunlight erodes the top layer of the wood. The grain raises as it erodes and checks and cracks develop causing the top to eventually become rough. The cracks be and expand larger as the boards cup, twist and warp – pulling or eroding away from fasteners. The roughened surface will shift color and gather dirt, particularly on the horizontal surfaces. This generates effects as shown in the picture and is a slow process.
Rot is brought on by fungus and breaks down the wood much quicker than weathering. Mildew is an airborne fungus that lives like dirt, pollen, and wood on organic substances. In most of the U.S. the climate has the right mix of warmth and dampness that enables mildew to boom. In the event the wood stays moist, it develop rot and will bring and host other fungi. In climates that are predominantly cold and dry, decay is not as common or non-existent.Decay Resistant Wood Species Finished or bare, the top wood for outside projects is the heartwood from a species that withstands decay. Some woods that match the description are accoya, catalpa, cedar (Spanish, western red, asian white, or Alaskan yellow), chestnut, cypress (old growth is greatest), ipe, juniper, locust (black), mahogany (Honduras or African), mesquite, mulberry, oak (bur, white), redwood (old growth is best), sassafras, teak (old growth is best), walnut, yew, and pressure treated lumber.
Joined using an exterior wood finish that is correctly maintained, these species will appear great and last a long time outside. All outdoor wood finishes fall into two general classes – permeating finishes and picture forming finishes. Let’s investigate properties and their features.
Penetrating Finishes Strengths ⦁ Don't blister and peel off
⦁ Don't really have to be scraped or sanded – they wear away
⦁ Let the wood breathe and dry out
⦁ Simplest to implement and recoat
⦁ Natural appearing
Weaknesses ⦁ Offer little protection from wear and soil
⦁ Desire care more commonly than other products. Penetrating concludes generally last three months to a year on surfaces that are horizontal and double as long on vertical surfaces.
⦁ Do not bring out beauty and the depth of the wood
Penetrating finishes are got to soak to the wood surface and seal it. They don't offer any protection against wear and only somewhat protection from the sunshine, if any. Yet, penetrating finishes will be the simplest to implement and keep and come in an variety of formulas that includes water repellents (WRs), water repellent preservatives (WRPs), coloured WRPs, teak oils and tung oils, and semi transparent stains. Producers appear to be blurring the lines between these finishes which may help it become difficult to learn just what is in the can. A general rule of thumb is the more natural looking the less protection it offers and more often it's going to have to be rekindled, the finish.
