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.
Priming:
Concrete or sand and cement screeds – prime with Polycote Easi-Screed Primer.
Non-absorbent surfaces – prime with Polycote WD Primer.
Oily/contaminated surfaces – prime with Polycote OT Primer
Damaged DPM / Rising damp issues – prime with Polycote DPM Primer
Please refer to relevant Data Sheets for preparation and priming methods.
Mixing:
Measure 4.5L of clean water into a suitable sized bucket.
Gradually add the entire 20kg quantity of powder whilst mixing with a heavy duty slow speed drill and heavy duty mixing paddle.
Mix for at least one minute to allow the additives to dissolve and produce a homogenous mix. Do not mix more than can be applied in 25 minutes.
Do not add excess water.
Application
Underfloor heating must be switched off during this period.
A 20kg unit will cover a floor area of approximately 1.6m² at a thickness of 7mm.
Starting at the furthest corner from the exit pour the floor screed evenly onto the floor to the required thickness and allow the material to start levelling. Minimum thickness of 5mm.
The use of depth adjustable floats or a pinned/notched leveller is recommended to assist in spreading the floor screed to a constant thickness.
A spiked roller should be used immediately over the freshly poured screed to eliminate any bubbles trapped within the screed.
The next mix of material must be rapidly produced and poured along the wet edge of the screed as well as across the exposed floor.
Each application should be laid within 20 minutes of the area adjoining in order to blend evenly into the edge of the previously laid floor screed. 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 screed. Therefore, the floor topping should be applied to the entire area in one continuous operation.
Cementitious screeds are susceptible to damage from liquid and chemical attack (including prolonged or constant use of water) and should therefore be sealed suitably prior to the use of such products.
Avoid exposure to sunlight and draughts for 5 hours as this may cause premature curing and hairline cracks.
Pumped application
This screed is suitable for use in conjunction with professional mixer pump system, enabling continuous application of large areas. Please contact Polycote Technical Helpline for further information on our range of floor coverings.
Warning:
1) If the industrial floor screed is not spike rolled immediately and the screed begin to cure, roller spike marks will remain visible
2) Failure to disperse the air bubbles by spike rolling may result in a lesser impervious finish.
3) Do not add excess water
Finishing:
This floor screed may be used without further overcoating. However, a coloured or clear water dispersed epoxy coating such as Polycote Flortex SG may be applied as soon as the screed has initially cured.
This will act as a curing agent and help prevent premature drying and cracking, as well as strengthening and sealing the surface for protection against oil and other spillages.
Help and advice.
Polycote have a wide variety of floor coverings for a range of floors including those with underfloor heating systems, others are specifically designed with chemical resistant properties and abrasion resistance.
We have products specifically designed for the food industry. You might need it to be non slip or be easier to keep hygienic and clean.
If you want a selection of colours to make an industrial environment safer or more aesthetically pleasing, then our team of experts can discuss what is best for your concrete floor, warehouses, garages, or any other floor you have. No matter the problem, we have a system that will work.
