Prepping New Wood For TWP Stains

posted by TWP Help 763 Comments

Staining New Wood with TWP Decking StainsWhen applying TWP Wood Stains for the first time to new wood there will need to be proper steps taken. New smooth wood or decking is not ready to be pre-stained prior to installation or stained right after installation. It is best to follow the directions of the stain manufacturer when it comes to applying a coating to new wood for the first time, not the lumber yard or the paint store's as they do not understand the proper prep needed.

TWP and New Smooth Decking or Exterior Wood

It is important to understand that new smooth wood is not absorbent enough for the TWP Stains. New wood contains a higher moisture content and a "mill glaze". Mill Glaze is a waxy film that results from the fast turning blades that cuts the profile on a manufactured log. The high speed of the turning blades produces heat that draws sap and moisture out of the log. As it cools and dries, it creates a film or coating on the logs.  This will hinder the TWP's ability to penetrate into the wood grain.

Note: New Rough Sawn vertical wood/fencing can be stained right away with no wait and with no prep as it does have mill glaze and is very absorbent. Just make sure the wood is fully dry. If Rough sawn wood has aged or oxidized (grayed) then it will need to be prepped with Gemini Restore Kit. One coat for most instances of newly installed Rough Sawn wood. Continue Reading

How to Apply TWP Wet on WetTWP Stains are to be applied "Wet on Wet" when the wood is absorbent enough to handle more than 1 coat of the stain. This is typically for wood and decking that is older than 12 months and has been exposed to the elements. Applying the TWP "wet on wet" is similar to applying 1.5 coats of stain. The second coat covers twice as much square footage as the first coat.

Applying TWP "wet on wet" is very easy and not complicated once you understand the simple steps. Continue Reading

The TWP Stain Guide to Prepping a Deck

posted by TWP Help 30 Comments

With wood decks maintenance is vital to the structural integrity of the wood. Cleaning, prepping and staining a deck are the 3 main keys to deck care. With any deck stain, including TWP the prep work is crucial. No matter how superior the deck stain is it will not perform properly or give you the results you expect if the wood is not prepped correctly. The following is a TWP guide to prepping a deck that has never been stained or currently has TWP stain already on the wood. If you have a stain of a different brand, you will need to remove it with a stain stripper. See this for more info Switching to TWP Stains.

Cleaning the Deck

Prior to staining with TWP the deck needs to be cleaned thoroughly to allow for proper stain penetration. Use a quality wood cleaner like the oxygenated cleaner Gemini Restore-A-Deck. These types of cleaners are safer on the wood than bleach based cleaners and will effectively remove dirt, mold, mildew and grayed wood fibers. It is important to get back down to clean bare wood. Apply the wood cleaner as suggested by the label instructions. Let the cleaner dwell and soften up the pollutants before using a scrub brush or performing a light pressure washing.

If an old failing stain is present it must be removed. A wore down semi-transparent stain may clean off with an oxygenated cleaner. If the old stain is stubborn then you might have to use a wood deck stain stripper instead of a cleaner. Once the pollutants and any remnants of old stain are gone the deck should look new again.

Using a Deck Brightener

A deck brightener, also called a neutralizer is the next step after cleaning. Because the cleaners and/or strippers are caustic in nature they need to be neutralized. Apply the deck brightener immediately after cleaning and according to the directions. Then allow it to dwell for several minutes before rinsing off with water. This will lower the pH level of the wood and make the wood grain “pop”. This acidic nature of the wood surface will allow TWP stain to dive deep into the wood and result in a more professional like finish.

Dry Time

After cleaning and brightening the deck it needs to dry prior to staining. With a moisture meter you want 15% or less moisture content before applying stain. If you do not have a meter, typically 1-2 days of dry weather is adequate time for the wood to dry completely. Now the deck is ready for TWP stain. Following this TWP guide to prepping a deck will ensure the stain lasts longer, enhances the appearance and performs as expected.

Dry and Curing Time of TWP Wood Deck Stains

posted by TWP Help 19 Comments

TWP 1500 SeriesIt is good to know the dry and curing time of TWP (Total Wood Preservative) Stain prior to applying. Some people get in too big of rush and want to start putting furniture, plants, grills, etc. back onto a wood surface too soon after staining. It is best to allow TWP to fully dry and cure before allowing foot traffic and items to be placed on the surface.

Drying and curing time for TWP may vary depending on climate and weather conditions. Over application can also affect dry and curing times. TWP should dry evenly flat with no glossy areas. Glossy areas indicate over application of the product and will extend the dry and curing time of TWP. To avoid over applying TWP, allow the stain to soak into the bare wood for 30 minutes then wipe away or back brush any excess stain that has not penetrated the surface. Do not apply TWP if rain is expected within 48 hours. TWP can withstand light rain within an hour or so of being applied but it is best to wait for dry conditions prior to staining. Continue Reading

KDAT and TWP Wait Period for New Wood

posted by TWP Help 8 Comments

With newly installed treated lumber, it is necessary to wait an adequate period of time for the wood to season or dry out prior to staining it with TWP. New wood sometimes referred to as “green” wood, has a very high moisture content when it is new. Staining wood in this condition would trap moisture under the stain and potentially lead to mold, mildew, and wood decay issues. This can mean premature future costly repairs and replacement of the wood so it is best to wait. The seasoning time frame can be around 4-12 months give or take depending on the climate, weather and sun exposure.

To avoid having to wait months to stain your new wood you can use KDAT wood instead. KDAT (kiln dried after treatment) is wood that is dried in a kiln after it has been treated with the proper bug deterring chemicals. The wood is then put on the market and sold. It is slightly more expensive than regularly treated wood but it may be worth not having to wait as long to stain it. The wait time for staining new KDAT wood with TWP is about one month. This cuts down significantly on the wait time and may be the right option for you. Continue Reading
