Deck Stain-How to clean and maintain a deck
The beautiful days are back, and if you have a terrace, you surely want to enjoy it! However, after winter and spring, cleaning your deck may be necessary to take full advantage of it. Discover all our tips to help you maintain your deck.
When to clean a deck?
With the arrival of the sun, it’s time to clean your deck, but when to do it? Generally speaking, as soon as the weather starts to shine again, it’s the right time: mid or late spring most of the time, depending on the years and the weather. However, it is preferable that the terrace is dry to ensure effective cleaning. However, avoid periods of great heat; the cleaning products could dry too quickly and make a stain on your terrace.
You will need several days without rain if you are using a weedkiller, cleaning product. Indeed these products must impregnate your terrace and be completely effective.
There are several types of terraces; some cleaning solutions are more suitable, so we will give specific advice according to the terrace’s different types.
Clean a wooden deck
In general, we avoid using the high-pressure cleaner, and we prefer the brush broom. The pressure can remove the protective layers on the wood of your deck if it is recent enough. We recommend using a spatula in the space between the boards to avoid deposits that can soil your terrace in the long term.
If you ever have iron or steel furniture that you leave all year round on your deck, it can stain the floor with traces of rust or making marks. If the rust stains don’t come off by rubbing with your broom and soap, you can try applying an acidic solution. The mixture of lemon juice and coarse salt is very effective for this kind of stain (a whole lemon for a liter of water).
Clean a stone deck
The high-pressure cleaner is not recommended, it can quickly damage your stones, and above all, it can blow up pieces of joints. It is preferred to use the brush with hot water and soap or dish soap to clean. When rubbing, most stains and dirt come off quite easily.
Clean a tiled terrace
Likewise, the use of a high-pressure cleaner is not too advisable. If the terrace is really dirty, use a little reduced pressure, and holds the jet at a reasonable distance from the surface. It can damage your joints by making them porous. Also, tiling is the easiest surface to clean and can withstand successive cleaning. The broom brush with black soap, if the terrace is rather dirty, is a good solution. Add a little elbow grease on the parts with the stains, and your deck will be clean.
Dirt, grime, tannin, and mold stains
Although they appear clean, it is important to prevent pollen or debris build-up. In areas with humidity, pollen, or dirt, mold spots can develop. Mold needs some type of food to grow, such as grass, pollen, dirt, wood, and wood resins.
The best way to combat mold is to keep the surface clean and dry. Make sure that the water drains efficiently out of the cover. The cleaners and brushes that are recommended to remove mold or clean thoroughly are:
In most cases, the weathering process takes between 8 and 10 weeks, but it can vary depending on the location and specific use of the product, such as if it is a covered porch.
Avoid using rubber-backed mats, tarps, pool toys, and other non-porous items on the deck for a long period, as these items can discolor the deck surface.
Some products, such as sunscreens and insect repellants, contain chemicals that can alter the surface of decks, railings, porches, or perimeter joist decks. Before using these products on or near a deck, railing or porch, check the product labels and consult the manufacturer on the product’s effect on polymer materials.
Do not put PVC glue or similar products on the surface of any railing, deck, or porch, as it may discolour and permanently damage the surface.
Like any walking surface, decks and porches can get slippery in winter. Be careful when walking on the surface in these conditions. Most products containing calcium chloride can be used to remove ice without damaging the deck or porch surface.
The use of metal or plastic shovels with a metal edge will damage the surface of decks or porches, and it is not recommended to use them to clear snow from their surface.
Remember, always quickly remove any dust, clay, mud, or other construction products from your deck, railing, or porch, and do not cut any construction products on them.
