Heavy Duty Epoxy Resin Floor Screed
ProductDescription
A three-component solvent-free pigmented mortar screed based on
epoxy resins.
Uses As a non-slip, abrasion-resistant epoxy resin floorings of
5-8 mm thickness:Industrial floorings subject to moderate or heavy
loadingWorkshop and factory floorsMachine shops and
warehousesDepots and loading rampsHangarsStairsSuitable for use on
ventilated or non ventilated substrates such as: Concrete and
mortar.
Advantages Easy and fast to apply.Solvent-free, no fire
risk.Excellent adhesion to substrate.With the addition of
Sikadur
-507 trowelling aid, the screed may be
mechanically smoothed using a plastic coated disk.Non-slip,
non-skid finish.Excellent abrasion resistance.High mechanical
strength.Permeable to water vapour.
Product DataColour Natural, light grey, yellow oxide, red oxide,
chrome oxide green. Other colours
available on request (minimum order 300 kg)..Packaging Comp.
(A+B): 3 kg Unit.
Comp. C (Sikadur 506 EG): 30kg Bag.Storage Store in dry
condition at temperature between +5C and +30C
Shelf Life 12 months from date of production if stored properly
in original unopened packing.Note:Component (A), Sikafloor
-9l pigmented, must be thoroughly stirred with a
mechanical stirrer prior to each batching.Segregation may occur
after 10 hours.

Prime with Sikafloor
-94 Primer (Comp. A+B) when using a 1:7
screed mix. When using a more extended mix (1:10), the adhesion
of the screedwill be improved by the inclusion of thixotropic
additives in the priming coat asfollows:

Stir Component (A) thoroughly with an electric stirrer prior to
batching. AddComponent (B) in the correct mix ratio and mix for 2-3
minutes at a low speed.Place the correctly batched quantity of
Component (C) in the mixer (forced actiontype). Add the prepared
resin mix (Components A+B) while the mixer is running,and continue
to mix until a homogeneous and uniformly moist mix is obtained.
Method of Appl ication Place the mortar while the primer coat is
still tacky, and rake out evenly. Level witha beam laid across
steel screeding rails and finish with a steel float.
Cleaning Clean all tools and equipment immediately after use
with Colma Cleaner. Oncehardened, the material can only be removed
mechanically. Wash soiled hands andskin thoroughly in hot soapy
water.
