Can I have more uniform colours?
As slate is a natural product it is not possible to guarantee uniform
colours. If you have a specific requirement, we would advise that
you visit our warehouse/showroom and have a look at the actual stock
to avoid disappointment. Some slates will have less variation than
What is the difference between a calibrated slate, gauged slate
and natural ungauaged slate? How do I get them level?
A calibrated slate has been heavily machined on back and has almost
no variations in thickness, requiring almost no grading and the
least adhesive. If you buy an ungauged slate, it has simply been
split and both sides are riven. You must sort through these slates
and ensure the thickest tile is laid down first, then you would
bed all the others up to make them level. However these slates will
normally require more adhesive and labour to fit. A gauged tile
means its been lightly machined and has a flat bottom, allowing
tiles to lay evenly without rocking and these will have less variations
in tile thickness.
I want a slate floor but not too much texture/roughness which one
is suitable to use at home?
are 3 basic levels of texture, those marked named "Rustic"
are the most heavily riven, with the most texture, these would most
resemble an old farmhouse flagstone floors that have been laid many
years ago. Then we also have the lightly riven slates which have
very little texture, but still have to attractive natural variations
you get in natural slates. All the Brazilian slates come under this
category. The rest are between the two where they are not particularly
rough or smooth. If you do not wish to have too much texture we
strongly recommend you consider a Brazilian slate for your project.
I have bought a random pattern, can i get all the grout joints to
be all the same width?
No. It is not possible to achieve the same grout widths throughout
a random pattern. You can greatly reduce the variation in grout
line width by simply moving certain tiles closer or apart as you
lay them down.
Is slate suitable to use with underfloor heating?
Yes. Natural stones are very good thermal conductors and as such
transfer heat evenly and effectively.
Can slate be used for driveways?
Yes. You will need to ensure that the sub-floor is prepared correctly
for driveway use. We would recommend installing a concrete pad and
use a 30mm thick slate for driveways and all slabs must be fully
I have received my delivery but I can see some
little cracks/split lines in the surface and or side of the slate
are they ok to use?
Generally. The way to tell if a slate is really cracked is to tap
it, and if it makes a very dull thud (quite unlike a sound slate
without any cracks) then it should be put to one side and used for
a cut. Slate is formed in layers over thousands of years, it is
these layers that allow it to be split into tiles and slabs. Occasional
natural fissures and cracks are part of the slates natural characteristics.
Only if the crack or fissure is substantial and is through a large
percentage of the slate it will be not suitable to use. If you are
worried then please keep the occasional slate with these characteristics
to one side to use as a cut around the edge of the room.
I am on a budget can I use a thinner slate for my patio?
Yes if it is only for foot traffic, you can use a nonimal 20 mm
thickness slate, either install a concrete pad or ensure your installer
can prepare the ground so that there is no movement. It is not recommended
to use a thinner slate outside other than in exceptional circumstances.
Can Sandstone be used on driveways?
Yes. You would need to lay a concrete pad first. We would not recommend
20mm slate or sandstone for heavy use or big cars (i.e 4x4s and
bigger). We would also not recommend sandstone where cars will be
turning on the driveway. It is ok to use if cars are only going
straight up and down when being parked.
What is the best way to clean slate?
We recommend that all natural stone be sealed. For day-to-day cleaning
you can use a natural stone cleaner approved by the sealant manufacturer.
Or you can simply use some warm water and a light/diluted detergent,
however some sealant manufacturers say this may shorten the life
of the sealant.
Why is it recommended to buy extra tiles?
It is industry standard that you order extra 10% to allow for cuts
and wastage. For example if your room is 30 m2, you should order
33m2 as you will need to cut some tiles at the edge of the room,
often the smaller off-cuts cannot be used. The delivery cost to
send out a few extra tiles is far more than the value of the tiles.
It is also advisable to keep a few spares incase you need to replace
some tiles in future due to damage or future renovations.
Do I need expansion joints?
It is best to check with your tiler/builder with regards to whether
expansion joints are required in the area that is being tiled. Normally
no expansion joint would be required if the area is less than 10
meters. For areas that are 10 meters +, expansion joints would be
required every 8-10 meters. For areas that are 10 meters + and with
underfloor heating, expansion joint would be required every 6 meters.
I have heard some slates can rust. Is this common? Why does this
Slates rusting is very rare. This is due to the way slate is formed.
Slate is formed from river or sea sediments. Sometimes during the
course of the water, random pieces of pyrites or fossils or other
matter are also deposited at the same time. Most of these have no
adverse affects on slate, indeed some add to the unique characteristics.
Unfortunately on rare occasions some iron pyrites can cause rusting.
We are unable to guarantee there will never be any pyrites as it
is completely random. In these rare instances we would recommend
the rusting tile simply be removed and replaced.
I have finished my project but have some extra tiles, do you accept
No. Unfortunatley we can not accept returns. However it is always
advisable to have a few spare tiles incase of any damage or future
revovation works affecting some of the tiles. Please ensure you
have measured and re-measured the area correctly.
I have had 3 broken tiles on delivery. Will you replace or refund
We do not pack or send out any broken tiles, if you find a few broken
in transit these can be used as the cuts around the edge of the
room or patio. If you have noted on the delivery the goods were
damaged and it is over 10% then free replacements will be sent as
soon possible. Please see Delivery Terms on our website for further
information. Unfortunatley we cannot refund or replace a few broken
tiles broken during transport.
Why are there white patches appearing on the slates even though
they have been sealed?
There could be a few reasons for this:
1. The adhesive/grout was not cleaned properly before sealing
2. The tiles were not completely dry prior to sealing causing the
sealant to react
3. The tiles have been spot bedded so the adhesive patches are showing
through the tile
4. Sub-base: (a) there is no damp-proof course which is drawing
salt out through the tiles (b) there is a damp-proof course but
it hasn’t been allowed to cure/dry properly before putting
In such instances you can use LTP Grout Stain Remover or LTP Grimex
to remove the stains.
I have received my order but some slates look like they have scratches
and scuff marks on the surface, and small chips on the edges. Are
We do not supply seconds. Minor surface marks or scuffs are normally
caused by the tiles rubbing together during production or during
transit. These will not normally be visible once the slates have
been cleaned and sealed. The slates are hand split using chisels
and occasionally very small chisel marks may be seen on the edge
of the slates. This is characteristic of the stone and not a defect.
Do I need to seal the slates outside?
Yes. We do recommend the slates are sealed. Any natural or manmade
product may weather and/or oxidise when exposed to the elements.
Sealing the slates greatly reduces the likelyhood and degree of
either of the above.
Can I lay slates externally on spacer pads / pedestals.
Yes. We’d advise using a Brazilian slate in 30mm thickness,
maximum size 600x600mm.
Can slate be used on walls?
Yes. You would need to check with your builder/tiler to ensure the
wall is strong enough to hold the weight. Also ensure that an acrylic
bonding and priming agent is applied before tiling, and a suitable
adhesive is used.
Can I lay on to chipboard/ply?
Yes. You would need to ensure that the sub-floor is made as rigid
as possible with little or no movement. If there is still movement
then you can install additional ply ensuring you cross board so
joints are not at the same place. You must also use a flexible adhesive
to lay the tiles.
Can I get slates exactly like the sample that I have received.
Samples are to show an example of colour and texture only. It is
not possible to show all variations in one small sample. If you
are looking for a particular colour, we would recommend that customers
visit our warehouse.
I only need a few tiles to complete or finish the project, can I
collect from the Finchley showroom?
We do not stock any tiles in the Finchley showroom. All orders are
dispatched from our warehouse in Bridlington. However if you are
flexible and can wait, once we have 3 small orders, we can put them
all on a pallet to Finchley. The delivery charge would be split
3 ways at £20 each plus the value of the goods. Please note
we must wait until we have 3 orders to be able to bring a pallet
How many slate colours are available?
Generally there are shades of the following colours available, Blue
Grey, Grey, Grey Green, Green and Heather Purple.
• What is meant by Weathering, Semi Weathering, Fading,
A Non-Fading Slate is one which changes very little from when it
is first quarried and any slight changes will be relatively uniform
on the roof. Any slate which is not a Non-Fading slate is known
as a Fading slate or Semi Weathering or Weathering Slate. The amount
of colour change varies from product to product.
• What sizes of roof slate are available?
The traditional common sizes are 600x300mm, 500x300mm, 500x250mm,
How much of the roofing slate is visible?
The portion of the slate which can be seen is known as the Margin
and is dependent on the headlap and calculated as: (length of slate
– headlap / 2)
• What is the Headlap?
The Headlap is the measurement of the slate that is covered by two
layers of slate from the two courses above.
• Why is the Headlap Important?
The Headlap is what makes the roof watertight from Wind Driven rain,
the Headlap is increased on shallower pitched roofs and roofs with
greater site exposure
• How thick are roof slates?
Roofing slate vary in thickness a nominal 5-7mm is typical however
for Scotland particularly in the Highlands a heavier 7-9mm is traditionally
• Do roof slates need grading?
Yes, slate should be sorted into at least three separate grades,
(heavy, medium and thin).The thicker slates should be used on the
lower roof (eaves), medium slates in the middle of the roof and
thin slates on the higher roof (Ridge) section.
• What size of batten do I need to use?
Slate battens should be 50x25mm should be used in accordance with
British Standards BS5534 Part1 2003.
• What nails should I use for fixing the slates?
Copper or Aluminium nails should be used to British Standard BS1202
• What are slate and half slates and why do i need
to buy them?
A slate and half slate is used on the verge on alternate courses
to create the horizontal lap. A slate and half may also be required
on areas of the roof where slates need to be cut, for example around
roof lights, chimney stacks etc. The use of slate and half slates
ensures the width of any slate on the roof is more than the minimum
width allowed in British Standards BS5534 which is 150mm
• What is the best way of ensuring I get a quality
Purchase slates from a reputable supplier that can supply full documentation
for their products. Documentation should include independent test
reports, Declaration of Performance Certificates and written guarantees
on completion of the project.
I was not on site when delivery arrived. My builder signed for the
goods without checking and we have found some damaged/broken tiles.
The person signing for the goods must check the condition of the
consignment upon delivery. You have up to 20 minutes to check the
consignment. If the goods arrived in a visibly damaged condition,
customers must note this as damaged on the delivery receipt next
to their signature. You then have 48 hours to properly check the
goods and advise us of any excessive damages with photos. Signing
for the goods unchecked will prejudice any claim for damages against
the haulier. In these instances we cannot replace or refund any
pallet/packaging looks like it may have been damaged, but i cannot
see any broken tiles, How should I sign for the goods?
You must sign for the goods as damaged if you suspect it has been
damaged in any way. It is preferable to sign for it as damaged and
later find there's no problem, than sign for it as ok and later
find lots of damaged tiles. If you have not signed for the delivery
as damaged unfortunately we are unable to make a claim with the
haulage company. Please note if the damages are less than 10%, we
cannot make a claim against the hauliers insurance. However these
tiles can be used as cuts around the edges of the room.
My delivery arrived late, can I charge you for my builders time?
We arrange deliveries on behalf of our customers. Instructions are
sent to the haulage company once your order has been processed.
All delivery dates advised are provisional and should be confirmed
with you by the depot 1 day before delivery (for economy service
deliveries). We cannot be held responsible for any consequential
losses that may be incurred from late delivery (such as tillers/builders
time). We therefore do strongly recommend that you order any goods
for delivery at least 2 days in advance to allow for any unforeseen
events that may delay delivery.
• I live on a slope; can I get delivery to my property?
The driver will try his best to get as close to you as possible.
If in the unfortunate event he is not able to go up the slope, or
if it is not safe enough to unload on the slope, the driver will
then unload and leave the goods at the nearest access point on solid
level ground. If this is not suitable, you can check with a local
builders merchants and ask if they will be able to take delivery
on your behalf and then arrange for them to deliver to you. If you
would like delivery to be made to builders’ merchants, you
would need to notify us of this at the point of ordering.
• I have a gravel drive, can the goods be delivered
to my driveway?
Due to the weight of the pallets unfortunately goods cannot be delivered
on to gravel. The goods can only be delivered on to solid level
ground (not grass/muddy paths).
I live down a narrow lane can you deliver to me?
Our normal crates are 1000kgs these are delivered on 18t lorries
(approximatley the size of a dustbin lorry). If there is not enough
access for this then we can make a request for a 7.5t lorry, these
however have a maximum weight limit of 750 kgs per crate due to
smaller taillift. You must make us aware of any access restrictions,
such as low trees, sharp bends that may affect delivery.
How are goods unloaded from the delivery vehicle?
All Deliveries will be made using a lorry with tail lift and pallet
truck. The tail lift can only lower onto solid level ground; no
slopes, gravel, grass or mud tracks. The pallet truck can only move
on flat hard standing ground, either concrete or tarmac are most
suitable. There is no mechanical off load facility on the lorry.
Please note the driver will leave your order to the nearest practical
point of access. This is likely to be 'kerbside'.
Please note normal tail lift deliveries cannot be made to properties
on a slope. Special arrangements will need to be made and this may
incur additional delivery costs.
I only need a few tiles can I arrange for my own collection to avoid
the delivery costs?
Yes you can. Collection would need to be made from our warehouse
in Bridlington, East Yorkshire. If you would like to arrange for
courier collection you can do so at your own risk. If you would
like the tiles to be packed on a pallet for collection, a £20
plus vat packing charge will apply.
We make this service available to customers where it is not economical
to pack and send small orders where the value of the goods is low
in relation to the cost of the labour to pack the goods and delivery
charges. In these circumstances, the goods are sold ex-warehouse
and it is the customers’ responsibility that the goods are
checked on collection.
My order is below the minimum order value. Can you arrange delivery
If you have ordered from us previously and require some extra tiles
to finish an area, we can arrange delivery for you. However there
may be a £20 packing charge if the value of the goods is very
low. We strongly recommend that you order a few extra tiles incase
one or two are damaged in transit.
How long does it take from order to delivery?
Once an order has been placed and paid for in full, goods can normally
be despatched from our warehouse within 48 hours (extra time may
be required for cutting/bullnosing). Delivery from receipt of full
payment normally takes 5-7 working days.
