TWP® 200 Series -- Shake & Shingle

Texas Forest Products Lab testing shows the 200 series to be #1 system in the world in terms of longevity and color maintenance for Shakes & Shingles…lasting 2 to 10 times longer than any other stain or clear natural wood system on the market.A high solids, heavy-duty penetrative coating (penetration on aged shakes/shingles is ¼’ to 1/2” in 90 days), specifically designed to extend the service life of shakes and shingles. The primary function is to enhance structural integrity and appearance of aged roofing. The finish composition will minimize grain cracking, cupping, surface erosion, water absorption and surface attack from mildew and algae. Although the system is highly penetrative, the residual surface film is highly resistant to destructive organisms. The penetrative portion of the product absorbs into aged and porous wood, adding bulk to aged and brittle wood fiber. This restores lubricity and flexibility to brittle shingles. At 93%+ solids, these products comply with all federal and state V.O.C. (volatile organic compounds) regulations. The TFP Lab also found 200 Series does not increase fire hazard…200 Series high flash point oils actually make wood somewhat less flammable but is NOT a fire retardant.

Important NOTE: Relative to use on Wood Siding and Shakes & Shingles used for Siding/Fencing.

Primary use of the 200 Series is for Wood Roofing Shakes and Shingles including Cedar, Redwood and other absorbent woods and surfaces. For this use, it is the longest lasting product on the market.

Due to its very, very slow dry and ability to penetrate into wood for 90 days and longer, we normally do not recommend it for Wood Siding or Shakes and Shingles used as wood siding including shakes and shingles used for wood siding and fencing. Do not use on any sealed surfaces...all OLD coatings must be removed. Do not use on hardwoods or new, smooth Douglas Fir since the 200 Series will not be able to penetrate into the wood to cure...and will rub off on clothes, skin and pets.

We normally recommend the 400 Series with Ultimate UV package (best penetrating type...lasts the longest), 1500 Series and the TWP 300 Series ® for Wood Siding including Shakes and Shingles used for wood siding/fencing.

TWP® SHAKE & SHINGLE PRODUCT CODES

200 Clear, 201 H.D. Cedartone, 202 H.D. Redwood, 203 H.D. Gold, 205 H.D. California Cedar, 206 H.D. Russett Brown, 207 H.D. Butternut Brown (medium brown), 210 H.D. Slate Gray (light to med grey). For Dark roof colors, call FSC concerning proper mixes.

PRODUCT SELECTION: See Mold & Decay Climate Index Map

200 S.T. Clear: All applications where an aged silver to ash blond appearance is acceptable. TWP 200 Clear will allow greying of the wood--TWP 200 is not intended to maintain color. Greying will occur within 6-18 months. In coastal or high altitude areas with high Ultra-Violet radiation, nightly dew or excessive rainfall, use wood tone products #'s 201, 202, 203, 205, 206, 207, 210 for best results. Reapply every 2-3 years for best protection.

201 H.D. Cedartone: For moderate to severe use. The product has a high degree of transparency to minimize hiding natural appearance of wood grain. It is ideal for shingles that are in reasonably good shape and can be cleaned to a light buff or tan color with the recommended cleaning procedures. Use in areas with mold & decay indexes up to 90.

202 H.D. Redwood: Strictly for use where a deep, transparent redwood appearance is desirable. Recommended only for areas with an index of 90 or below. Great on redwood and cedar shakes & shingles. Do NOT use on white or light yellow woods, such as pine, spruce, or Douglas fir.

203 H.D. Cedar Gold: Use for most severe aged conditions. It is slightly more opaque than 201 and provides additional protection from extreme ultraviolet rays. The additional color strength provides color uniformity on surfaces that remain dark after cleaning and exhibit burnout from intense radiation. It is the preferred product in southern coastal areas with a mold and decay index of 70-130 and in high UV light regions within the 0-30 index. Do not use on wood less than 10 yrs old as it will show "too yellow." Use straight if wood has considerable grey and blotchiness after power wash. Blend TWP 203 with 201 for most applications at 50:50 mix.

205 H.D. California Cedar: Our favorite color formula for aged shakes and shingles when the desire is to restore the natural beauty of the light cedar color to your roof or sideway project. In other words, this product is designed to restore the natural cedar color for aged cedar installations.

In restoration projects, 205 H.D. works perfectly in moderate and extreme climates (hot or cold). Great choice for surfaces that are dry and brittle and where cleaning still leaves some gray or darkened surface color. The net effect is to produce a more immediate color change to simulate newer wood. Good for trying to blend new and aged wood as in roofing repairs and additions.

206 H.D. Russet Brown: This product is designed to restore or maintain the natural cedar color for all cedar installations. In restoration projects, TWP 206 is perfect where the wood surface can be power washed to a relatively new appearing shingle (or shake) or where there is still life left in the roof (replacement of 15% or less of the roof is desirable). This is our favorite for use on new shakes or shakes less than 5 years old.

207 H.D. Butternut Brown: Identical to 206 except that additional brown pigment has been added to produce a warm, medium brown color. Same benefits as 205 & 206.

210 H.D. Slate Gray: Formulated to produce a pleasing light-to-medium grey semi-transparent tone similar to driftwood color. Same benefits as other pigmented colors.

PLEASE NOTE: Products 201-207 take approximately 6-8 weeks to achieve final color tone. The products always appear dark upon application…before oil penetration. 201-203 may be intermixed for color modification.

SURFACE PREPARATION & ROOF REPAIR

Prior to cleaning, replace cracked or severely cupped shingles. If the surface is above 15% defective, it is advisable to re-roof. Pay special attention to ridge caps. For best appearance use good aged shingles from the back of the house to replace unusable shingles in the front. Insert new shingles in old shingles place in a concentrated area as close to the bottom as possible. This procedure will give the front of the home a more uniform appearance and keep the roof from having a blotchy appearance from the insertion of random new shingles.

When fastening new shingles, be sure to use non-ferrous nails or staples. Dip galvanized fasteners are preferred. Sound shakes with minor cracking which have not begun to cup may be underpinned with galvanized sheet metal or polypropylene slip-sheets cut to the overlaying shingle size. They are easily installed using an exterior grade construction adhesive. Use 15- 25 mil polypropylene sheet stock or standard thin gauge galvanize. Plastic is the easiest to install. Other plastics, such as flexible vinyl or Mylar may also be used. Run an adhesive bead on back edge and sides. Do not apply to bottom edge. Lift the cracked overlaying shingle slightly and slide the slip-sheet under the shingle with the adhesive faced down. Press the top shingle down to secure the slip-sheet to the shingle scraper to insure adhesive contact with the surface. Allow at least 24 hours before the roof is power washed.

ROOF CLEANING of Aged Roofs with Light Organic Growth for “Like New” Appearance

The surface must be cleaned to remove dirt, algae, moss, mildew and loose wood fiber. Depending on climate and age of the roof, one or all of the conditions may exist. The most common method is power washing with chemical assistance. Z-90 Wood Magic Plus ™ is ideal since it restores color by retrieving “natural tannin color” from inside the wood to a “like new” visual condition in most cases (up to 10-12 year old roofs, Z-90 Wood Magic Plus ™ generally does a great job to restore the “like new” color) and makes mold/algae/mildew growth removal much faster. This will allow the use of lower pressure power washing (2000 to 2500 psi ideal for TRAINED professionals; allows cleaning technician to can keep the tip further from the wood surface speeding up cleaning and minimizing wood “fuzzing”/breakage), thereby reducing the risk of creating more damage from high pressure/”close cleaning tip to the wood” water blasting.

Warning: Do NOT use household Chlorine Bleach as it does not work on mold/algae and will HURT color retention and can breakdown or “fuzz” the wood fiber.

IF ANY COATINGS ARE PRESENT, THEY MUST BE REMOVED for TWP 200 to penetrate & protect the wood. Z-90 Wood Magic Plus ™ used straight or 1:1 with Hot Water will remove many old stains 80-90% with power washing. Chemical Stripping may be necessary if Z-90 Wood Magic Plus ™ does not work to your satisfaction.

Roof Cleaning of Moderate to Heavy Organic Growth Removal SOLUTIONS

For organic growth removal: Z-90 Wood Magic Plus ™ applied @ 3 to 1 dilution with warm water is ideal for newer to aged wood; for heavy mold/moss and discoloration or greying, use Z-90 Wood Magic Plus ™ @ 2 to 1 or 1 to 1 dilution…very heavy mold/moss may take a couple of treatments. Allow to set and penetrate 15 to 30 minutes before power washing. The delivery pumping system should be low pressure in order to prevent misting.

Components must be chemical resistant plastic or stainless steel. The objective is to deliver the solution to the surface with minimum overspray or pressure. Always start applying chemical at the bottom of the roofline. This prevents rundown of dirt and chemical into dry porous surface. Pump-up garden sprayers such as Hudson2 (stainless steel) or Maya 2(plastic) are adequate where production time is not essential. Power washers with after pump chemical siphon feed work well for fast production. Make sure that the gun, pole and tip assembly is steel or stainless steel. Keep the equipment a minimum of 50 feet from the point of application and keep covered with plastic. The working life of the solution is 5-10 minutes. Follow up with power wash rinse to remove loose residue.

CAUTION: Do not allow bleach or acid cleaners to come in contact with aluminum windows, doors or mechanical equipment. Keep plant foliage in the immediate application area wet. Take all measures possible to prevent misting. Wear rubber gloves, splash goggles, and any equipment deemed necessary for personal protection. Water rinse all application equipment thoroughly after use. Cover plants and foliage with plastic. In hot weather, remove plant cover as quickly as possible.

POWER WASHING

Standard power washers generating 1500-2500 p.s.i. are adequate. The size is somewhat dependent on the experience of the user. More powerful equipment may be used for faster cleaning, provided the user has the experience not to damage the surface. Proper technique requires roughly a 45% blast angle from the plane of the surface, disregarding the roof pitch. Operate at maximum pressure and adjust the tip distance to the surface short of fraying or splintering the wood. Always work with the grain. Pay special attention to the channel keyways and remove debris accumulation. Always work down slope. Apply vertical blast to remove debris from butt ends carefully. Trim old jumbo shakes with badly frayed ends with a high-speed rotary trim saw.

APPLICATION

After product selection and a minimum 24 hours of drying after cleaning, product may be applied. There are many pumping mechanisms to apply product. Avoid excessive overspray by adjusting pressure to minimize misting. Most commonly used is airless spray equipment in the 1/2 to 1-1/2 gals/min pump capacity. The gun assembly should include a 3-foot extension pole with a .032 to .040 swivel wide-angle spray tip. This will allow the applicator to keep the spray close to the surface and away from him. It is preferred to spray a 3' section laterally across the roof and ending the bottom of the pattern as close to the shingle butt line as possible. This is done to avoid lapping. This is not a two-coat system. See spread rate table for approximate coverage. Use mineral spirits for equipment cleanup and save for re-use. This product may not be disposed as conventional waste. Rinse containers before disposal.

DO NOT CONTAMINATE GROUND WATER OR OPEN WATER TO PREVENT DAMAGE TO AQUATIC LIFE. USE PERSONAL AND PROPERTY PROTECTION AS PROCEDURES PRESCRIBED IN THE MATERIAL SAFETY DATA SHEET. CLEAN UP OVERSPRAY WITH SOAP AND WATER. THE USER ACCEPTS RESPONSIBILITY FOR DISPOSAL OF WASTE AND EMPTY CONTAINERS IN ACCORDANCE WITH EXISTING GOVERNMENTAL STATUTES.
