Three difficult exterior issues that affect paint appearance and longevity are all caused by excessive moisture. Minimizing the moisture problem first and then renewing the substrate with quality Diamond Vogel paints is the key to success.
影響油漆外觀和壽命的三個棘手的外部問題都是由水分過多引起的。最大限度地減少水分問題，然后用優(yōu)質的金剛石沃格爾涂料更新基材是成功的關鍵。
MILDEW
霉菌
Mildew is an unsightly fungus that can grow on many surfaces including paint. The mildew feeds on nutrients available in both the paint film and the underlying surface. Most important for mildew growth is moisture, so it is commonly found in damp, dark places frequently under eaves and behind shrubbery.
霉是一種難看的真菌，可以在許多表面生長，包括油漆。霉菌以漆膜和底層表面的養(yǎng)分為食。霉菌生長最重要的是水分，所以通常發(fā)現(xiàn)在潮濕，黑暗的地方經(jīng)常下檐和后面的灌木叢。
Mildew must be removed prior to painting. Mix one part of bleach with three parts of water. Scrub the area thoroughly while protecting yourself by wearing rubber gloves, eye protection and other protective clothing. Don’t allow the bleach/water mixture to dry out on the surface. Rinse the area thoroughly and allow the area to dry. Repaint the area as soon as possible. We recommend two coats of Diamond Vogel's Permacryl Exterior, Weather-Plate, or EverCryl Acrylic Latex.
在涂漆之前必須除去霉斑。把一份漂白劑和三份水混合在一起。徹底擦洗該區(qū)域，同時戴上橡膠手套，護目鏡和其他防護服，以保護自己。不要讓漂白劑/水混合物在表面變干。徹底沖洗該區(qū)域，并允許區(qū)域干燥。重漆地區(qū)盡快。
Allowing more sunlight and better air movement to reach the affected area will help minimize the return of the mildew, so pruning trees and thinning shrubbery are important steps.
讓更多的陽光和更好的空氣流動到達受影響的地區(qū)將有助于減少霉菌的返回，所以修剪樹木和稀疏的灌木是重要的步驟。
TANNIN STAINING
單寧染色
Tannin is a naturally occurring, water soluble substance found in many varieties of wood. Tannin can be pulled to the surface in the presence of water and leaves behind a brown or tan stain. Tannin staining issues are more likely to develop from red cedar, cypress and redwood. While these stains do not harm the integrity of the paint film, they are unsightly.
單寧是一種天然存在的水溶性物質，可以在許多種木材中找到。 單寧可以在水面上拉到表面，留下棕色或棕褐色的污跡。 單寧染色問題更可能由紅柏，柏樹和紅木發(fā)展而來。 雖然這些污漬不會損害漆膜的完整性，但它們不美觀。
The best way of preventing tannin staining is by applying a tight film of paint over the substrate minimizing the ability of water to penetrate. In the past, solvent-based alkyd primers were the choice to prevent tanning staining. However, solvent-based primers tend to become brittle, crack and peel with age.
防止單寧染色的最好方法是在底材上涂上一層緊密的油漆，最大限度地降低水滲透的能力。 在過去，溶劑型醇酸底漆是防止鞣制染色的選擇。 然而，溶劑型底漆會隨著時間的推移而變脆，開裂和剝落。
Diamond Vogel developed Sure Grip Exterior Acrylic Latex Primer to combat tannin staining and peeling issues on exterior wood substrates. Sure Grip applied in two coats with twenty-four hours in-between coats, does an amazing job preventing tannin bleeding. Topcoat with Permacryl Exterior, Weather-Plate, or EverCryl Acrylic Latex for a long lasting, beautiful paint job.
鉆石涂料開發(fā)肯定握丙烯酸外墻乳膠底漆，以打擊單寧染色和剝離木材表面的問題。在兩層外套之間涂上二十四個小時，確實可以起到預防單寧流掛的作用。隨著天氣變化外，丙烯酸乳膠面漆用于持久，美麗的油漆工作。
EFFLORESCENCE
風化
Efflorescence is a white or tannish, powdery deposit on concrete or masonry substrates. While typically not structurally damaging to the substrate, it is unsightly and destroys the paint on the substrate. Efflorescence occurs when moisture migrates through concrete and masonry substrates, dissolving salts contained in the material. The moisture deposits the salts on the surface of the substrate and evaporates, leaving the powdery deposit.
在混凝土或磚石基材上，花序是白色或者淺褐色的粉末狀沉積物。 雖然通常不會在結構上損壞基材，但是不美觀且破壞基材上的油漆。 當水分通過混凝土和磚石基質遷移時，會發(fā)生風化，溶解材料中包含的鹽分。 水分將鹽沉積在基材表面并蒸發(fā)，留下粉末狀沉積物。
Prior to rectifying the ruined painted surface, the source of the moisture must be found and stopped, or the process will reoccur. Once the moisture has been stopped, remove the existing efflorescence and loose paint by using a stiff wire brush. Clean the surface to remove all the dirt, debris and other contamination. Prime the surface with either Diamond Vogel's Weather-Plate Exterior Acrylic Latex Primer or Sure Grip Exterior Acrylic Latex Primer, followed with your favorite color in either Diamond Vogel's Permacryl Exterior, Weather-Plate, or EverCryl Acrylic Latex.
在糾正被破壞的油漆表面之前，必須找到并停止水分的來源，否則過程將再次發(fā)生。 一旦濕氣停止，使用硬鋼絲刷去除現(xiàn)有的風化和松散的油漆。 清潔表面以去除所有的灰塵，碎屑和其他污染物。 使用外部丙烯酸乳膠底漆或外部丙烯酸乳膠底漆，使用您最喜愛的顏色。
