: Pool Question - Mastic

05-03-2009, 02:46 PM
I need to replace the "mastic" (not sure of the spelling).. It is the expansion joint between the pool deck and the coping. I stopped by Leslie's Pool Supply, and they had no idea what I was talking about.

Where do you get it??

I live East Dallas (Rowlett - Garland area), and if there is a "pool person" on the forum looking for work... Well - reply to this message. Otherwise, I will do it myself if I can locate the supplies.

Leslies *used* to carry it, but they may not anymore. I need to replace mine, too. A ruberized calk will work fine, but it isnt east to find either. Post up when you locate it.

Edit, they still have it. http://www.lesliespool.com/browse/Home/Pool-Deck-Repair/Deck-Protectors/Deck-O-Seal-One-Step-Dura-White/D/30100/P/1:100:17000:1700020/I/26270

Fun stuff, easy to put down..just the prepwork can be fun depending on the size of pool and the depth of the gap. May need sand/ or foam to fill joint.

For what it's worth... The SIKA product from Home Depot is (hands down) the easiest expansion joint sealant I have ever worked with. Truly self-leveling, and looks professional when complete.

I am returning the Dura-Seal for the pool as Home Depot has the SIKA in sandstone, and is quite a bit cheaper then the "one for a pool". I did the driveway yesterday, and it looks perfect. Will sprinkle sand on top of the SIKA for the pool to give it a better look...

if the joints are wide and/or deep fill them half way up with baker rod.(round foam)the use the deck-o-seal.sprinkle sugar sand over the caulk before it drys.

looks very nice.g/l

I picked up a bag of "play sand" but it looks too coarse for finishing. Where do you buy sugar sand??

Thanks.. I used the play sand, and have to admit - it came out better than expected.

For those of you who are replacing the mastic on your pool - go get the multi-purpose tool from Harbor Freight. It is on sale for $40-bucks, and made the removal so easy...... I love this tool. I used some backer rod in the joint, and left about 1/2" depth for the Sika to fill. Did the pool in 10-foot sections <e.g. removed the old sealant, backer rod in areas that was too deep, sandstone color Sika (Home Depot), and sprinkle sand on when it self-levels>. Looks perfect, and I am glad that I didnt spend the money on te DuraSeal.
