Managing Paver Patio stains
How to avoid them, how to remove them.
FOLIAGE AND ORGANIC DEBRIS
Concrete is a porous material that can absorb pigments from leaves, petals and buds from trees/shrubs. Organic stains can be tough to remove if they stay on the pavers beneath the snow or when left on damp surfaces for a period of time. We recommend that you sweep away dead leaves regularly. If you live in an area that is prone to more foliage, consider protecting your paved area.
Using a protectant can make your pavement more stain resistant and easier to keep clean. Note that there is no need to use a protectant with Klean-Bloc products as they are already sealed.
Organic Stain Remover also removes mildew, algae, kills moss and tough stains from tannins.
Depending on the product collection, remedies vary. See below our recommended solutions and directions on how to remove organic stains.
WET-CAST/NON KLEAN-BLOC PRODUCTS: Mix 1/3 liquid chlorine (pool shock) with 2/3 water and a small amount of ammonia free dish soap. Add together and mix in a plastic sprayer or bucket.
DRY-CAST PRODUCTS: Mix 1/2 household bleach with 1/2 water and a small amount of ammonia free dish soap. Add
together and mix in a plastic sprayer or bucket
DIRECTIONS:
Pre-soak area to be treated and let water absorb into pavers.
Apply cleaning solution in manageable areas at a time.
Scrub area with nylon brush or broom. For Wet-Cast, KleanBloc or natural stone products, use a microfibre cloth.
Rinse area and repeat as needed.
NOTES:
Clean in cool temperatures and out of direct sunlight.
Always test in a small inconspicuous area.
Don’t allow soap to dry.
The goal is to remove the stain without harming the surface
of the pavers. Therefore, patience and multiple applications
may be required.
Do not attempt these solutions on Klean-Bloc or natural
stone products. Simply use a mild, diluted dish-washing soap
in warm water and a microfibre cloth
RUST
Some fertilizers contain iron that can leave stains on the surface
of your patio. After spreading lawn or plant fertilizer, be sure to
sweep the surface of your pavement to prevent rust spots.
Rust stains from steel or iron, such as patio furniture, fertilizer
or high iron content water (irrigation) can be removed using
professional products such as Gator Rust Remover or household
iron removers.
FOOD AND BEVERAGE
Food or beverages (like wine) spilled on the pavement should be
removed quickly and the area should be rinsed with hot water
immediately. Liquid dish soap or laundry detergent will remove
most food and beverage stains on pavers. Mix a solution of the
soap or detergent with hot water and gently brush the stain
away with a cloth or a soft-bristled brush that you have dipped
into the mixture.
OIL AND GREASE
Light oil and grease stains can generally be removed with an
application of liquid dish soap. Directly apply the soap to the
affected area and let sit for 20-30 minutes, scrub with a nylon
brush and rinse with hot water. Re-apply and repeat until the
stain is removed. If it is a fresh stain, lightly rub the area with a
clean rag or paper towel.
If an area is heavily soiled, a professional product such as Gator
Oil and Grease Removal® may be used. Please refer to product
