MAPEI® Mapesil T™ Caulk | Silicone Sealant - #A4610

Do you have any questions about this product? Call (888)355-6287, or email us.

I tested this silicone sealant and could not get a smooth bead. Instead it discolored the wood molding and was difficult to clean off the tile. I thought it would be like other silicone caulks. It seems to be more of an adhesive than a regular silicone caulk.

HI Craig, Thank you for your question. Please refer to the product data sheet located in the "Specifications" tab on this product page. It says, "Mapesil T may stain porous materials. Test a small area for staining or leaching before use to ensure compatibility with such porous materials as natural stone." Thank you, The Koffler Team

Can this be used in floor tile where the grout has come out?

Hi La Rae, Thank you for your question. Yes, this can be used in grout areas that has come out. However, it should not be used to grout an entire floor. Thank you, The Koffler Team Thank you, The Koffler Team

I need a SANDED grout to fill holes in between bricks in an old old house. It must be sanded as mice don't like to chew thru sanded grout. Ivory 39 is what I need. Do you carry this?

Hi Katelon, Thank you for your question. Yes, here is the link to our A4634 sanded grout that has the color Ivory (39). http://kofflersales.com/p/keracolor-s-premium-grout.asp?cid=3712 Thank you, The Koffler Team

Three questions: How close to the actoual color are your color charts? How long does it take this product to dry? Is this the right product to seal inside a shower where the floor meets the wall? Thank you.

Hi Fred, Thank you for your questions. As for the color, it is close to what's on the product page, except it all depends on your monitor resolution. You may also request a free sample at samples@kofflersales.com The drying time is 24 hours. Yes this is the right product to seal inside a shower were the floor meets the wall. Thank you.

is Mapesil T silicone caulk 100% mold and mildew resistant? I need to use it in a steam shower. GE Silicon II, and other products that I have used in my regular tub/shower, last for about a year. I want something that will not get mold or mildew for at least 10 yrs or more if possible.

Hi Brenton, Thank you for your question. Unfortunately, we would not recommend this product for the high temperatures that occur in a steam shower. Thank you, The Koffler Team

Is the mapei mocha (42) a sanded silicone? Does it have the silicate added to give the illusion of grout?

Is the Mapesil silicon sealant paintable? and if so can it be painted with latex or oil-based paint?

Hi Cher, Thank you for your question. Unfortunately, this product is not paintable. Thank you, The Koffler Team

can i use the Mapesil 100% silicon sealant around the toilet base. Will this stain the porcilen?

Thank you for your question. There should not be any staining, but as with anything like this, you may want to try a small area first.

This silicone is awesome stuff. Works just like the best silicones I used for years but has a perfect color match and no sheen. The matte finish blends seamless with their grout. Has great performance and tacks up fast.

Bought this to caulk corners and vertical joints on my tub after the tile guy used grout and it cracked. I cleaned it up a bit and then applied this caulk...it matches the grout really well and makes a nice clean joint. Excellent and just what I wanted.

IT IS AMAZING THAT THE COLOR BLENDS PERFECTLY AND THAT WHEN APPLIED TO HARD GROUT CRACK AREAS, IT STANDS STRONG AND RESISTS THE TYPICAL CRACKING OF THE HARD GROUT.... THIS WAS A LIFE SAVER FOR ME WHERE THE WOOD COLUMN POST CONTACTED THE COUNTER GROUT.... GREAT STUFF!!!!

Best Silicone for showers hands down.

Mapesil T is the best silicone for showers. 100% silicone but does not have a sheen like standard silicone making it blend with your grout better than any other.
