Stone Seam Pro Clear Knife Grade Seaming Adhesive – Master Pouch 3L

This Stone Seam Clear 3L pouch is the master pouch size of Stone Seam Pro Clear, a crystal clear two-part methacrylate (MMA) knife grade seaming adhesive for quartz, granite, marble, porcelain, glass, and sintered stone. The hardener and mixing cups and sticks come in the box. Three liters in one pouch means fewer pouch changes than three 1L pouches, and the fill is more than three quart cans.

Clear is the base for seams that need transparency, and the starting point when you build a color from clear. Look up your slab in the Stone Seam formula tool for the pumps of pigment and hardener. Full specifications, working time, and chemical resistance are on the Stone Seam Pro Clear Knife Grade Seaming Adhesive page.

Package Details

Performance in Production

• The hardener is already in the box, so there is nothing else to order to start mixing.
• The screw cap closes the pouch between mixes. Cans and pails often get left open, and silica and dust that fall in can affect the seam color.
• The foil pouch squeezes out nearly all of the resin, where a can or pail always leaves some behind.
• Mix by the cup, never the whole pouch. Large masses of mixed material build heat, so mix only the amount in your formula and what you can place and clamp inside the working time.
• Resin shelf life runs 12 months from the date of manufacture at room temperature. Keep the pouch out of excessive heat, since an acrylic MMA is temperature sensitive, and match the pouch size to how fast your shop uses resin.

Frequently Asked Questions

How much resin is in the Stone Seam Pro Clear master pouch?

The master pouch holds 3 liters of Clear resin, which is more than three quart cans. It comes with a 4 oz bottle of hardener and mixing cups and sticks.

Does the Clear master pouch come with hardener?

Yes. The hardener is in the box, so you do not need to order it separately. Replacement hardener is sold in 2 oz and 4 oz sizes if you need one.

Can I mix the whole 3L pouch at once?

No. Mix by the cup using the amounts in your formula. The TDS warns that large masses of mixed material generate heat that can boil the monomer and release trapped air, steam, and volatile gases, so mix only what you can place and clamp inside the working time.

How do I color match the Stone Seam Clear master pouch to my slab?

Look up your slab in the Stone Seam formula tool or phone app and follow the formula for your feet of seam. Because the resin is crystal clear, the pigments build the whole color. Mix the pigment into the resin, check the color against the slab, and add the hardener last. Test the match on a scrap or offcut before you run the seam.

Is the master pouch the same Clear resin as the 1L pouch and the packs?

Yes. The resin is the same in every size, and only the quantity and packaging change. The Clear product page lists the 1L power pouch, the power pack of ten 1L pouches, and the master pack of five 3L pouches.
