My contractor is using this product. How soon can he paint it with a solvent based sealer? Will it adhere?
This product fully cures in 5 days. It remains flexible. It doesn't state that it can be painted in any of the data sheets.
Will it repair water leaks in a basement?
Hello Mike:Yes and No, let me explain. The best approach to stopping water leaks in your basement is to correctly waterproof the buildings foundation wall from the exterior. This is an expensive project, digging down to the footing of the foundation on at least one or more sides where the water is entering your basement and applying either a rubber membrane or Bituane sheeting this product is made by GRACE. The rubber sheeting is manufactured by Firestone and others. It needs to be installed professional with a drainage mat placed over it to prevent rocks from cutting the rubber. This is not a DIY project for most home owners.Sikaflex needs to be applied to a dry surface that is clean and free of dirt or other contaminants. I would advise opening the cracks where the water is entering about 1/4" and apply a 1/4" bead into the crack. Yes in the short term it will work. Sikaflex used indoors can last as long as 15 to 20 years as it is not exposed to the elements and UV light(Sun). Good LuckBest Regards,ChrisSikaflex cleans up with mineral spirits when still wet. Drying (curing) time is between 24 to 48 hours for a 1/4" application.
not sure because I used it for cracks in concrete on a pool patio. I would uses something more like thompsans water stop or a water block paint
I've used it and similar Sikaflex products to seal cracks in a concrete swimming pool deck. There is some shrinkage due to the sun and heat exposure.
Most likely NOT. It is designed for sealing cracks in horizontal surfaces that are subject to expansion and contraction. When the product is applied it seeps into cracks for terrific bonding and then dries as a flexible rubber seal. If used on horizontal joints it will most likely just run out. Sikaflex does make other products for horizontal joints. Check their website.
what color is it and is it paintable?
Its labeled "limestone" , but its a shade different than cured concrete. It is paintable, however we did not paint it.
It is light gray. I have not tried to paint over it.
What kind of paint can be used in painting this product?
I painted the sealant on cement walls with Behr from Home Depot but I guess any paint should be okay.
Although I've used this product extensively to seal joints between blue stone and brick, I have never tried to paint it. I can however recommend the product. It lays down really well and provides a great seal. Sorry I could not be more helpful.
Can you paint over it with latex paint?
Yes...........in fact, that's my preferred paint.
will this seal asphalt cracks?
Not the best item for asphalt. Would probably work but there would be a stark color difference. Plus I'm not sure if there would be a chemical reaction between the sika and the asphalt components. I'd go with a product designed to be used with asphalt. Maybe a tar/petroleum based product of sorts. Unfortunately I'm not familiar with any so I can't recommend one.
I used it to seal concrete cracks and gaps and it remains perfectly seals after two seasons of snow and sun attacks. Never used it on asphalt but I believe it would work just as well. Maybe I should try as regular asphalt filler is peeling off after one winter.
will sikaflex seal asphalt cracks?
Yes. I manage a HOA swimming pool and we used sikaflex about 3 years ago to seal cracks on the concrete deck. There are a few places where it shrunk a little after curing that I am repairing. We also had some places where the ants dug out under the deck and we filled those with old filter sand. After it settled, we topped off the sand and replaced the sealant.
I live in Huntington Beach, Orange County, California. Can this products be used for the expansion area between pool coping and concrete slab? Can I fill most of the area with sand first? The gap is aprox 1" wide and 3/4" deep.
Yes, in fact, it would be a great idea and an almost forever fix. Sikaflex 1CSL is an outstanding product with I've used alot over 25 years.The gaps can be filled with 'backer rod', which is simply round foam/insulation that comes in many different sizes. For your 1" wide gap, I'd buy 1 1/4 in. backer rod because it is very flexible/pliable and you want a tight seal so that the Sikaflex will not sink between the backer rod and slab. Bigger is better in this instance. You can always squish the backer rod down to fit gaps. A tight seal is imperative unless you want to waste both the product and $. Place the backer rod uniformly 3/8-1/2in. below the height you want the Sikaflex to set, apply, wait 4-5 days for full cure, paint with latex paint if desired a week or so later......enjoy!!
As the previous poster noted, this product will work very well for your intended project.
I need to repair a concrete pea gravel driveway. Will the limestone color work? I'm not sure what color limestone is.
Thanks so much!
You can paint on the sealant after it is completely dry if the color does not match well. Unlike typical driveway sealant, Sikaflex does not peel off even after two snowy winters and hot summers.
Hello MiChal:Sikaflex 1C SL 1, limestone is a light gray color. That said if you choose to use it to seal cracks the cracks must be free of loose debris and dry. If the crack is deep it is best to use backer rod to fill the crack and then apply the Sikaflex. The manufacturer recommends 1/4 inch depth. I have applied as much as 1/2 inch dept and it worked. Drying time can range from 24 to 72 hours depending on the depth of the joint/crack, weather and temperature. The deeper the crack/joint the longer it takes to cure. Good Luck and wear disposable gloves. Tool clean up is esay with mineral spirits.
what is dry time for this product?
It never completely dries even after two winters and two summers as it always retains its rubbery texture. It took about 24 hours to lose its stickiness.
Hi:24 hours to a setup and 48 to 96 hours to a full cure. This product is best used at over 50 degrees Farinheit.
Works just like it should
This product will seep deep into cracks creating a tight bond and when dry remains flexible
Does the job
We use this product to seal cracks in concrete and expansion joints at a fuel facility in SoCal. Its self leveling so its good for horizontal applications only. It flows evenly thru out the cracks we are repairing.
SAN DIEGO, CA
I can not think of any other self leveling sealant that works this well. EASY TO USE AND LASTS FOREVER.
Good product if you know the limitations
Used Sikaflex to caulk cracks in asphalt. Cracks need to be narrow and shallow. Product is pretty liquid and actually ran out of cracks if applied to high. I would use this product again but I now know that cracks need to be filled in, otherwise you use more of the product than necessary.
Greatest product I have ever used,
BEST concrete sidewalk filler I have ever used - have used 4 differetn products. Exceeds label expectations and claims. I even used it on asphalt driveway cracks that had previouly been filled by aspahlt filler for 5 years that have not done the job.Waaaaay too easy to use. Hardest part is puncturing the seal. Neighbors and church want me to fill their cracks.
