High Performance Two
Component Adhesive
(Ref. SIPL / TDS / PU / 0421 / R-01)
Product Description
MYMIX - THIXOFLEX - PU is two component Polyurethane Adhesive, designed for permanent bonding of
wide range of ceramic and vitrified tiles, large size tiles, glass mosaic, sensitive natural marbles, granite stones
slabs and synthetic / engineered stone on interior & exterior walls and floor areas. THIXOFLEX - PU adhesive
is also suitable for superior bond strength on substrates such as plywood, glass or metal. It also provides
balanced thixotropic and superior performance elasticity ensured by the use of stabilized polyurethane resin
for rapid and secure laying operations on high deformable and high-expansion substrates.

How to Apply
Surface Preparation
The surface should be clean and free from wet, dirt, oil or grease before applying the adhesive
Ensure that the substrate is always dry, flat, stable, well adhered and has a normal absorption
In case of undulations, correct the local undulation/damage on the substrate at least 48 hours before
the application
To get flat substrate on concrete or cement surfaces; prepare mortar using MYMIX SBR 330 / SBR
LATEX for better performance
Clean the back of tile / stone for any dust or loose particles. Tile or stone must be absolutely dry while
laydown on PU Adhesive
The proper preparation of the surface will make the fixing easier and quicker ensuring a better finish
The surface should be flat with a tolerance of 4 mm over a distance of 2 meters
It is essential to waterproof wet areas prior to application
New concrete is recommended to be 1 month old and completely dried before application
Cement substrate should not be subject to shrinkage after the installation of the product therefore they
must be properly cured
Depending on the substrate condition; contaminants to be removed from the surface, perform
adequate preparation techniques such as grinding or blastcleaning in order to remove all traces of any
material that could reduce the product's adhesion to the substrate
Rust on iron based or metal based substrates must be removed before application
On non-absorbent substrate, check to confirm that surfaces are firmly and securely bonded and stable
Substrate must fulfill the requirements of the local standards, be properly cured, structurally sound,
dimensionally stable, free of any loose particles
Mixing Details
Take Part A & B as per mixing chart
Particulars 1 Kg Pack 5 Kg Pack
Stir properly to get homogeneous mixture
Part A - Resin 800 gm 4 Kg
Mixing can be done by hand or ele. stirrer
Part B - Hardener 200 gm 1 Kg
Ensure no unmixed material left in mixture
Note : Not recommended for partial quantity of mixing components.
Application
Use the proper sized notched trowel to ensure full bedding of the tile
Use 6mm x 6mm notch trowel for stone & regular tile applications by which get 2-3mm total bed thickness
For glass mosaic or slim tile applications use 3-4 mm size of V-notch trowel to maintain 1.5-2mm bed
thickness

Application
TM
When both waterproof and bonding are required, use flat edge trowel to spread THIXOFLEX - PU layer to
maintain a thickness of 1-2mm, then rework the surface with a notched trowel for tile installations
Now apply the adhesive on the substrate with the flat side of trowel initially, press firmly and spread the
adhesive on the substrate. Then comb the adhesive with notched side of trowel
To provide full bedding & firm support, apply back buttering on the back side of tile before fixing
Bed the tiles firmly into the adhesive with a slight sliding and / or twisting action /shear, to ensure a good
and uniform contact, fix or adjust the tiles within 30 minutes
Beat in using a beating block and rubber mallet to imbed and adjust level check regularly to ensure that
the back of the tile is in full contact with the adhesive
Ensure tiles should be laid and adjusted before adhesive grooves get skinning
Occasionally check the adhesive coverage/contact by flip or lifting the tile. It helps to verify proper contact
area/adhesive transfer is achieved to avoid voids
Ensure adequate gap (grout joint) is kept between subsequent tiles to accommodate for thermal expansion
& contraction when tile or stone installing especially on dry wall boards like cement backer board,
gypsum, plywood board, calcium silicate board etc. Use spacer to get uniform thickness of grout joints
Carefully remove excess adhesive immediately from the joints
Allow to cure the adhesive for 24 hours before grouting
Grout Recommendations
Joints can be filled after 24 hour of completion of tiling work
Based on the applications Ritepoxy ESG-1200, Glitter Star, TR, EIG-2200 and Cementitious grouts
(CGU) can be applied which are available in more than 28 colours
Refer Technical Data sheet of Ritepoxy ESG-1200 and Cementitious Grouts for more detail
Notes on Application / Limitations
Do not apply the adhesive on damped or wet surfaces
Clean the application tools when the material is fresh
Do not add any other materials to the mixture or components
