Details
Recommended For: Preparing surfaces such
as cleaned concrete, wood, plywood, gyproc and
cement boards.
Surface Preparation: The concrete, masonry
or wood/plywood surface must be clean and free
of all dust, grease, and other foreign material
prior to the application of Starpatch 900X. For
specific details of usage with each Starpatch
mortar product please read the particular mortar
Product Data Sheet available from Starpatch
Concrete Products.
Mixing Instructions:
• Apply 900X directly to the substrate and
allow it to become tacky or dry completely
before applying topping mortars. The new
concrete topping will re-emulsify the surface
to give an extreme bond. 900X will not reemulsify once the topping mortar has set.
• As a polymer modifier do not exceed a
dilution ratio of 3:1. When using 900X with
non-polymer modified toppings or mortars a
2:1 dilution ratio is recommended.
• When Starpatch 900X is used as an additive
or as a primer, please read and follow the
instructions written in the pertaining Product
Data Sheet.
Application: Brush (preferred), spray or roll on
to substrate and allow product to become dry or
tacky before applying topping mortar. Brush
Starpatch 900X with a scrubbing motion to form a
uniform film, without puddles, over the entire
surface. Starpatch 900X will dry in 1 to 3 hours.
Place cement topping within 3 days for best
results, provided the substrate is kept clean. If
topping cannot be placed within 3 days, reapply
Starpatch 900X.
Technical: Starpatch 900X is a Styrene Acrylic
Copolymer dispersion, which is designed to
modify hydraulic binders (Portland cement).
Starpatch 900X has good resistance to light and
aging.
