Product Information

Impex Stone London decorative stone combines a refined white finish with a texture inspired by architectural stone. It brightens the room and is installed indoors, on walls and fireplaces.

  • Box of stones covering 8.66 sq. ft. (0.8 m²), in three lengths (50, 30 and 20 cm), 10 cm high.
  • London white corner available in boxes of 10.5 lin. ft. (32 pieces): choose the “Corner” option above.
  • Install with LTC white adhesive mortar (white is required for white stones), back-buttering: 3/8 in. trowel on the wall, flat trowel on the stone.
  • 1/4 to 3/8 in. joints in Type N King 1-1-6 mortar, applied with a mortar cone the day after installation.

⚠️ Never clean with water: colours may bleed. Vacuum or use a feather duster. Decorative stone is porous: in a kitchen, Impex Stone recommends applying a sealer, 28 days after jointing. On a fireplace, wait 30 days before lighting it.

Substrate preparation

  • Recommended substrate: lightweight concrete board (DuROCK®, PermaBASE®).
  • Painted gypsum board accepted without lath up to 8 ft high; galvanized lath required above that.
  • Plywood: asphalt paper then galvanized lath, at any height.
  • Filling the lath: allow one extra bag of adhesive mortar per 30 sq. ft.

Quantities

  • LTC adhesive mortar: one 50 lb bag covers 40 to 50 sq. ft. with the recommended tools.
  • King 1-1-6 mortar: one bag covers 30 to 40 sq. ft. with 3/8 in. joints.

Frequently asked questions

The colour of the stone I received differs from the sample panel. Why?

The main feature of natural stone is that it is natural. As a unique product of nature, it shows its own variations in shade and colour. These variations are not defects: they are part of the stone’s beauty and unique character.

My installer put up stones that seem defective. What can I do?

As the warranty and installation guides state, an installed stone is a stone accepted by both the installer and the customer, even if the customer is absent during installation. The best way to avoid this is to take the stones out of the boxes yourself before installation, to mix them and create the look you want.

Some adhesive mortars set faster than others. With one of those, can I install more than 4 feet in height per day?

No. Fast-setting adhesive mortars shrink as they dry, and that shrinkage can crack the stones. Use LTC adhesive mortar (grey or white), formulated specifically for these stones.

I feel like a pro this morning. I think I can install at least 8 feet of stone in height today. Can I?

No. Stone is not ceramic tile: install no more than 4 feet in height per day, so the adhesive mortar has time to work properly.

I bought stones and corners. Where should I start the installation?

Start with the corners, then install the stones.

How many square feet does a bag of LTC adhesive mortar cover?

A 22.7 kg bag covers 40 to 50 sq. ft. with a 3/8 in. trowel, and 20 to 30 sq. ft. with a 1/2 in. trowel. For stone on mesh or masonry stone installed indoors, allow 20 to 30 sq. ft. per bag.

I bought a marble stone or a white stone. Which adhesive mortar should I use?

Marble and white stones must be installed with white LTC adhesive mortar. Marble is very porous: a grey adhesive mortar would stain it permanently.
