The only weather resistant self-levelling concrete resurfacer, that will withstand freeze/thaw cycles and stresses of weathering.
Suitable Substrates
Easi-Screed External is designed primarily for use on power-floated or tamped concrete, along with existing cementitious & anhydrite based screeds.
Colour
Easi-Screed External is grey in colour, subject to slight variation depending on current raw materials, mixing and application conditions.
Packaging
Easi-Screed External is supplied in 25kg bags.
Preparation:
Thorough substrate preparation is essential.
Follow recommendations given on the relevant primer Data Sheet. See ‘Priming’ below for the primer appropriate to your application.
Mixing
Measure 4.5L of clean water into a suitable sized bucket.
Gradually add the entire 25kg quantity of powder whilst mixing with a heavy duty slow speed drill and mixing paddle.
Mix for at least two minutes to allow the additives to dissolve and produce a homogenous mix. Allow the mix to stand for 1 minute after which time the free-flowing screed will be ready for application directly onto the prepared substrate.
Application
Starting at the furthest corner from the exit pour the material evenly onto the floor to the required thickness and allow the material to start levelling.
The use of depth adjustable floats or a pinned/notched leveller is recommended to assist in spreading the screed to a constant thickness.
A spiked roller should be used immediately over the entire area to eliminate any bubbles trapped within the screed. Failure to spike roll may result in a porous surface as the bubbles escape whilst curing takes place.
The next mix of material must be rapidly produced and poured along the wet edge of the material as well as across the exposed floor.
Each application should be laid within 25 minutes of the area adjoining in order to blend evenly into the edge of the previously laid material.
This can be helped by gently trowelling along the joint.
Once the workable time has been exceeded it is not possible for the new material to be blended into previously applied material.
Therefore the floor topping should ideally be applied to the entire area in one continuous operation.
Cementitious screeds are susceptible to damage from chemical attack and should therefore be sealed suitably prior to the use of such products.
Application Thickness
The recommended range of applied thickness is from 2mm – 25mm in one layer. For filling deeper areas please contact our technical helpline on 01234 846 780 for advice.
