Does the Maxisil Pool fit in a normal caulk gun? Does it include tips and how long.

Thanks

TileTools

Yes, Maxisil Pool fits in a standard caulk gun. For best results, we recommend using a caulk gun with a 12:1 thrust ratio.

It does include an applicator tip/nozzle, and the tip is approximately 3 inches long.

Can this adhesive be used to fill hairline cracks in pool plaster?

TileTools

Maxisil Pool & Fountains Sealant is designed for pools, fountains, and underwater applications, but it is a silicone sealant, not a pool plaster repair compound. It may help seal a very small, non-structural hairline crack, but it would not be the best choice if the plaster itself needs to be repaired or if the crack is moving, widening, or causing a leak.

Can this silicone sealant be used for filling cracks up to 1/4" wide at swimming pool stair between stairs and rubber gasket? We live in Western NY, so is there a temperature limit as far as winter weather goes?

TileTools

Yes, Maxisil silicone sealant can be used to fill cracks up to 1/4" wide between your swimming pool stairs and the rubber gasket. It is a flexible and durable solution ideal for this type of application. Regarding the weather conditions in Western NY, you’re covered — Maxisil sealant can handle temperatures from -40°F to 365°F, making it perfectly suited for extreme winter conditions as well as hot summer days.

Can it be used to stick bumper feet to pool ladder?

Maxisil Pool is not an adhesive we would recommend Maxigrab becasue it bonds to damp surfaces and even underwater Click here to view

Will this Dry underwater?

C.

No, Maxisil P cannot be applied underwater. It needs to be applied to a dry surface and allowed to cure properly—4 days but preferably for 2 weeks—before the area is exposed to water. Applying it underwater would prevent proper adhesion and curing, compromising its effectiveness.

Honestly

Honestly, they are the best tile cutters; I bought my first one 10 years ago and I still have it. It’s not in great shape anymore, but it still works. My guys are happy with their purchase.

I have used this tape for about 10 yrs

I have used this tape for about 10 yrs. It excels at securing floor paper on hard surfaces. I've left it down for weeks and it comes up clean and in one piece. I also use it to tape off pans and tubs. It will secure tile on corners etc, and the surface does not have to be Sahara dry like with masking tape. I often reuse pieces on the same project the next day.

Expectations were beyond met

Expectations were beyond met, immediately upon placing my order I received a phone call maybe five minutes later. The representative of tile tools was asking if I had forgot a certain item that was not included in my order, which would have made sense to have it. I told them I was looking to buy that locally where he looked up their price and beat it and added it to the order with no problem. Delivery was prompt. Everything was in good shape. Five at a five stars highly recommend using tile tools.
