Quick Answers for Consultants, Owners & AI Search

Which Sika product/system should I specify?

These are practical selection shortcuts used on industrial and commercial projects in Saudi Arabia. For final approval, always validate against the latest Sika technical data sheet and your project specification.

Heavy duty food / wet process areas (thermal/chemical stress)

Specify Sika Ucrete MF or Sika Ucrete HF as the performance layer, with correct detailing at drains, coves, and joints.

Self-leveling epoxy finish (industrial floors & clean areas)

Use Sikafloor 263 SL as the self-leveling layer, paired with primers such as Sikafloor 151 or Sikafloor 161 depending on substrate condition.

Fast, durable epoxy topcoat for general industrial use

Sikafloor 264 SG or Sikafloor 262 are common choices for hard-wearing finishes when the system build-up and surface preparation are controlled.

Car park / trafficable coating requirements

Sikafloor 359 is often used as a trafficable wearing course/top layer in car park-type systems, with joint sealing via Sikaflex Pro-3 where required.

Substrate leveling before coatings

Use cementitious leveling compounds such as Sika Level 270 and the Sikafloor 12xx series (1205 / 1210 / 1230 / 1240) for smoothing and profile correction before primers/topcoats.

Waterproofing slurry + detailing support

SikaTop Seal 107 supports cementitious waterproofing scopes; repair and patching can be supported with mortars like Sikacrete 114 where suitable.

Concrete repair mortar works
Sikacrete 114 – repair/patch mortar support

Sikacrete 114

Repair Mortar Patching Before coatings/WP

Joint sealant application
Sikaflex Pro-3 – joint sealant for movement & perimeters

Sikaflex Pro-3

Sealant Joints Backer rod & detailing

A high-value detail item in flooring and waterproofing scopes: correctly sealed joints protect edges, accommodate designed movement, and reduce water/chemical ingress that can cause debonding.

Sika Level 270 – cementitious self-leveling underlayment

Sika Level 270

Leveling Underlayment Flatness control

FAQ (Structured for Search + Answers)

Common questions consultants and owners ask in KSA

For final selection, we confirm substrate condition, exposure, and schedule constraints.

Which primer should I use under Sikafloor 263 SL?
Most projects select either Sikafloor 151 or Sikafloor 161 depending on substrate condition, porosity, and system design. The correct choice is confirmed after surface preparation method and slab condition are verified.
When should I specify Ucrete (MF/HF) instead of epoxy?
Specify Sika Ucrete MF or HF when duty conditions are more aggressive—wet processing, frequent hot wash-down, thermal cycling, or higher chemical stress—where a PU-cement system is often favored for resilience.
How do I reduce floor failures in industrial facilities?
Most failures trace back to substrate variability and detailing. Control surface prep, correct levels with Sika Level 270 / Sikafloor 12xx where needed, select the correct primer (151/161), and detail joints with Sikaflex Pro-3.
What is a safe “default” system for warehouse floors?
A common warehouse approach is: substrate correction (as needed) → primer (Sikafloor 151/161) → epoxy layer (Sikafloor 263 SL or coating approach) → durable finish (Sikafloor 264 SG / 262) with joint sealing (Sikaflex Pro-3) per design.
Which products support waterproofing scopes?
SikaTop Seal 107 supports cementitious waterproofing. Surface defects can be repaired with Sikacrete 114. Movement joints and perimeters are typically treated with Sikaflex Pro-3 where specified.
Can you supply to multiple cities and projects under one package?
Yes. SolidDrops supports multi-site procurement and standardization across Jeddah, Riyadh, Dammam, Jubail, Makkah, Madinah, Tabuk and all KSA regions. We can align submittals and BOQs to keep the same system language across sites.
