All products needed to build a wedi Fundo Primo point drain shower are included and provide a single manufacturer
warranty.Safe transportation in one box,easy estimating of product quantities needed.The shower floor units feature a
strong and pre-sloped surface which can be tiled over immediately whether you choose mosaic size or large format tile.
Pre-sloped extension panels are available so that virtually no limit exists for making any size or shape for custom shower
designs happen. Naturally,Fundo Primo is insulating keeping surfaces warmer. Especially when compared to traditional
mortar bed installations or other currently known methods for building showers such as those including use of sheet—
or liquid waterproofing membranes used in an attempt to manage water exposure—wedi Fundo Primo's simplicity and
high performance shows. The most unique advantage, however, is the complete and natural core waterproofness of
the wedi product and its completeness and range of components that will form an entire assembly system with Fundo
Primo engineered to fit and last.This is a true system with full warranty coverage.

wedi Fundo Primo Product Information
These added values and its detail perfections eliminate the technical concerns in shower installations.However,this is not where wedi shower systems stop
offering its added values.The wedi Fundo shower system adds to your productivity and enables you to provide real value to your customers.Our wedi Fundo
Shower systems reduce the installation time for just the shower floor from a 2-3 day process(includes drying times)to only 30 minutes when compared to
traditional methods built with pre slope,vinyl liner and final mortar bed.wedi helps you to turn showers into service quicker,cleaner and safer.Especially
for our contractors,Fundo Primo helps to get to setting tile faster and on a much more consistent and the friendly surface.Customers will appreciate the
"no noise and no dirt/dust"installation.The wedi products do not contain harmful ingredients providing peace of mind to contractors and end users.
Note for Installation
Optionally a glue drain can be obtained from wedi.For a cement glue connection,the floor pipe must be cut 2 1/4"below the surface of the subfloor.
Optionally a brass drain can be obtained from wedi.The installation proceeds as shown for the standard ABS drain provided with each Fundo Primo base.

Note 2 in.outside diameter is nominal(2 3/8 in.for PVC/ABS schedule 40 pipe and 2 in.for cast iron/copper).Several Fundo Primo models naturally
feature different perimeter height or thickness at the edge.Therefore,pre-made standard notch connections of wedi curbs must be modified in
the field for a tight fit to the bases.Ramps and Extension panels can naturally not fit to all models and might be modified in the field as well.

After Installation
All visible joints or seams in the installation are visibly covered and reinforced with wedi Joint Sealant applied flat over the seams.Coverage of wedi Joint
Sealant over all seams should be at least 1 inch(25.4 mm)on either side of the seam.The wedi Joint Sealant should be no less than 1/16 inch(1.6 mm)
thick for strength,Do not add mesh tape into the wedi Joint Sealant.This may only put the waterproofing performance at risk and will not strengthen the
sealant's or system's resistance against movement related stresses.Once wedi Joint Sealant application over all shower system seams has been completed,
an optional water flood test may be performed as early as 2 hours later.The test should not exceed 24 hours and nor should the water level exceed the
height of the perimeter seams so that the fresh sealant may continue to a full cure without too much weight added during that process.wedi recommends
to test at least the drain connection for its proper seal while a full surface flood test is not technically required for non-absorbing products like wedi but
may be required by a building inspection department.When tiling commences,no premixed and organic("mastic")file adhesives must be used over wedi
Systems in any wet area installation.When tiling the wedi Shower Bases,ind.extensions or ramps,tile thickness should generally not be less than 1/8"(3.2
mm).Choose setting materials appropriate for the type of stone,ceramic or glass tile as well as for a wet area installation.Tile with a square size of 2 x 2"
(50.8 x 50.8 mm)or more may be installed using a polymer modified cement based tile adhesive and grout.Tile with a square size of less than 2 x 2"(50.8
x 50.8 mm)may be installed using a polymer modified cement based the adhesive and require 100%solids epoxy grout.Tile with a square size of 1 x 1"
(25.4 x 25.4 mm)or less must be installed using a 100%solids epoxy file adhesive and grout Only non-flat bottom pebble stone installations including
in part small mosaics may be installed using polymer modified cement based the adhesive and grout,all fiat bottom pebble stone installation are subject
to the general tile size based setting materials recommendation outlined above.When installing non-square tile,the length of the shortest file edge(s)is
considered as its square size for the purpose of determining the choice of the setting materials as outlined above.
All file installations designed to receive heavier paint loads such as from wheelchair use,must be grouted using 100%solids epoxy grout.large format tile
may be installed over vvedi Fundo shower bases.Cuts may have to be made in consideration of the base's slope lines and so that such tie can always be
fully supported by the file adhesive setting bed and the surface of the wedi Base.Tile adhesive coverage under the file must be 95%and special care must
be taken to achieve good transfer of adhesive to wedi's Shower Base when working with mesh backed tile.Use only solvent and acid free cleaners and
sealers on tile and grout installed over wedi product and apply such products only in amounts as needed to treat the surface materials without drenching
the substrate.Follow setting materials manufacturer's recommendations and contact wedi with any questions or regarding applications not covered here.

ica(TCNA)2014 Handbook for Ceramic Glass and Stone Tile Installation(SR613-14 and 5R614-14).
d)The wedi waterproof Fundo Shower system accessories which may include the following water-
proof components:wedi pre-sloped curbs,wedi niches,wedi seats,wedi fasteners,wedi drain cover
plates,wedi sealants,wedi Fundo drains,wedi Subliner sheet waterproofing membrane system and
tapes,with wedi Sublimer Dry Bonding flange drain„vredi Subliner Dry Tub Sealing Tape.
The wedi Fundo family line includes the following:Primo,Riolito Neo,Riolito Neo Modular,Rici ino,
Discreto,t gno and OneStep.The wedi Fundo Shower system components and assembly for shower
installations were proven to be waterproof,water-resistant,and mold resistant when tested in
accordance with Al 18,10-2014 and ASTM E331.The wedi drains have found to comply with with
ASME At 12.1&2/GSA B125.2 and do not require weep holes.
Conditions of Listing 1.The wedi Fundo Shower Systems shall be installed in accordance with the manufacturer's
