Takeaways
- 🏗 Natural stone is an ancient and versatile building material with a wide range of colors, textures, and shades.
- 🛠 The video provides instructions on laying natural stone paving on a wet mortar bed, distinct from the method for laying porous slim paving.
- 📏 Assessing the long-term stability of the existing ground is crucial at the beginning of a project to ensure the project's success.
- 🔄 The preparation of the bedding material involves mixing clean water, coarse sand, and cement in specific proportions.
- 💧 It's recommended to wash down the back of each paving stone to facilitate the laying process.
- 🛤️ Spread the bedding material in a layer that is 25 to 40 millimeters thick, larger than the area of the paving stone to be laid.
- 🔨 Use a rubber mallet to tap the paving stone down to the correct fall and check the level with a spirit level.
- 🔍 The suggested layouts allow for an average joint of 10 millimeters, which will be filled with mortar or other pointing material.
- 🔄 For jointing, use a product like Aspects Easy Joint, which involves soaking, sweeping, and washing into the joints to create a slurry.
- 🌈 Natural stone colors intensify and darken when wet but will return to normal once the paving dries out.
- 📚 For more detailed information on laying natural stone, refer to the installation guidelines provided on the specified website.
Q & A
What is natural stone used for in construction?
-Natural stone is one of the oldest building materials known to man, used for its wide variation in color, texture, and shades, suitable for various construction projects.
What are the different types of natural stone mentioned in the video?
-The video mentions veined marble, slate, and sandstone as examples of natural stone types.
How is natural stone paving laid on a wet mortar bed according to the video?
-The video explains that a layer of freshly mixed bedding material, roughly 25 to 40 millimeters thick, is spread over an area slightly larger than the paving stone to be laid.
What is the purpose of washing down the back of each paving stone?
-Washing down the back of each paving stone can help with the laying process, possibly by ensuring better adhesion to the mortar bed.
What tools are suggested for spreading the bedding material?
-The video suggests using a shovel or a brick trowel to spread the bedding material.
How should the paving stone be positioned on the bed?
-The paving stone should be positioned allowing for the appropriate joint thickness and then tapped down to the correct fall with a rubber mallet.
What is the recommended joint thickness for the paving stones?
-The suggested layouts in the video allow for an average joint thickness of 10 millimeters.
What is used to fill the joints between the paving stones?
-The joints are filled with a mortar or other pointing material, and in this project, Aspects Easy Joint is used.
How should the Aspects Easy Joint be applied to the paving?
-First, the paving is soaked, then the Easy Joint is wetted to form a slurry, which is swept and washed over the saturated paving into the joints.
What happens to the color of natural stone when it gets wet?
-When natural stone gets wet, the colors intensify and darken, but they return to normal once the paving dries out.
Where can one find more information on laying natural stone?
-More information on laying natural stone can be found in the installation guidelines at www.globalstonepayment.co.uk.

Highlights
Natural stone is one of the oldest building materials with a wide variation in color, texture, and shades.
The video explains the process of laying natural stone paving on a wet mortar bed.
Laying porous slim paving is explained in a different video.
Project sites vary, requiring judgment on the long-term stability of the existing ground.
A small mixer is used to prepare the bedding material with water, sand, and cement.
Washing the back of each paving stone can assist with the laying process.
Bedding material should be spread in a layer 25 to 40 millimeters thick.
The bed surface should be rippled to allow some give when the stone is placed.
Position the stone with appropriate joint thickness and tap it down with a rubber mallet.
Use a spirit level to check the stone's level after tapping it down.
The suggested layouts allow for an average joint of 10 millimeters.
Joints are filled with mortar or other pointing material, such as Aspects Easy Joint.
Soak the paving and wet the Easy Joint to form a slurry before application.
Sweep and wash the saturated paving into the joints, and top up as required.
Use a soft broom and hose for watering after applying the jointing material.
Natural stone's colors intensify and darken when wet but return to normal when dry.

Transcripts
natural stone is one of the oldest
building materials known to man with its
wide variation of color textures and
shades from veined marble through to
slate and sandstone
this video explains how to lay natural
stone paving on a wet mortar bed
for laying poor slim paving this is
explained in another video
every project site is different and a
judgment will have to be made at the
start of the project as to the long term
stability of the existing ground
using a small mixer put a half bucket of
clean water into an empty drum add four
to five shovel fulls of coarse sand and
one shovel full of cement
it can be beneficial to wash down the
back of each paving stone in order to
help with the laying process
use a shovel or a brick trowel to spread
the freshly mixed bedding material in a
layer that is roughly 25 to 40
millimeters thick and extends over an
area just larger than the paving stone
that is to be laid ripple the surface of
the bed so there is some give when the
paving stone is placed
position the stone allowing for the
appropriate joint thickness and tap it
down to the correct fall with a rubber
mallet checking the level with a spirit
level
our suggested layouts allow for an
average joint of 10 millimeters with the
joint being filled with a mortar or
other pointing material
this particular project uses aspects
easy joint
firstly soak your paving
wet the easy joint to form a slurry then
sweep and wash over saturated paving
into the joints
top up as required
use a soft broom pointing tool and hose
for watering
natural stone is wet
the colours will intensify and darken
this will return back to normal when the
paving dries out
to sum up use a small mixer to put half
a bucket of clean water into a drum with
four to five shovel fulls of sand and
one shuttle full of cement
use a shovel or brick trowel to spread
the materials in a layer roughly 25 to
140 millimeters thick which extends the
area just larger than the paving stone
always use a full bed of mortar under
the paving not spot bedding as this
leaves voids that can affect the
performance of the paving
position the stone allowing for
appropriate joint thickness
tap it down to the correct form of a
rubber mallet and check the level your
spirit level
a day later apply jointing materials
such as aspects easy joint over
saturated paving
