Question 1

What is Fosroc NitoFill UR63 Base with Hardener and what is it used for?

Accepted Answer

Fosroc NitoFill UR63 Base with Hardener is a two-component epoxy-based filler designed to repair cracks and holes in concrete and masonry. When mixed, it forms a durable, waterproof repair material suitable for both interior and exterior surfaces.

Question 2

Which substrates can I use this UR63 kit on?

Accepted Answer

It can be used on concrete, masonry, and metal substrates. Prepare the surface by cleaning away dust, oil, and loose materials and ensure the area is sound and dry before application.

Question 3

How do I mix and apply Fosroc NitoFill UR63 Base with Hardener?

Accepted Answer

Mix the correct base-to-hardener ratio thoroughly until a uniform color is achieved, then apply with a suitable trowel or putty knife. The self-leveling formulation helps achieve a smooth, uniform finish with reduced post-application work.

Question 4

What kind of finish or appearance should I expect after application?

Accepted Answer

The product has a self-leveling, smooth finish that adheres well to the prepared substrate, providing a uniform repair with a neat appearance suitable for concrete and masonry surfaces.

Question 5

How long does it take to cure and when can I resume normal use of the treated area?

Accepted Answer

UR63 cures quickly, with initial set allowing handling after a short period and full cure completing within a day or so under typical conditions. Temperature and humidity can affect cure speed, so warmer, drier conditions generally shorten curing times.

Question 6

Is NitoFill UR63 waterproof once cured?

Accepted Answer

Yes. The kit is designed to form a waterproof repair membrane, providing long-term sealing suitable for areas where moisture exposure is a concern.

Question 7

What safety precautions should I take when using UR63?

Accepted Answer

Wear appropriate PPE such as gloves and eye protection, ensure good ventilation, and avoid skin contact. Since it is an epoxy system, follow safe handling practices and wash off any spills promptly with soap and water before it cures.

Question 8

How should I prepare the surface before applying the UR63 kit?

Accepted Answer

Clean the surface to remove dust, oil, and loose material. Remove any laitance and ensure the area is dry and sound. For best adhesion, lightly abrade glossy surfaces and remove any residues before applying the epoxy.

Question 9

How should I clean up after using UR63 and how do I dispose of leftovers?

Accepted Answer

Clean tools with warm soapy water while the material is still uncured. Once cured, epoxy can only be removed mechanically. Dispose of any waste and packaging in accordance with local regulations.

Question 10

How does Fosroc NitoFill UR63 Base compare to the UR63 Hardener and to separate components on Fepy?

Accepted Answer

UR63 Base is the resin component, UR63 Hardener provides the curing agent, and the UR63 kit combines both for convenience. Using the base with the hardener yields the complete epoxy repair system, while the separate components allow flexibility in quantities.

Question 11

Is buying the UR63 Base + Hardener kit a better value than purchasing components separately?

Accepted Answer

Generally, the combined kit offers convenience and ensures compatible proportions, which can translate to savings in time and potential waste reduction compared to sourcing base and hardener separately. Compare pricing and consider project size to determine value for your specific job.

Question 12

What is the typical coverage and how do I calculate how much I need for a project?

Accepted Answer

Coverage depends on the porosity of the substrate and the thickness of the repair. For planning, estimate the area to be repaired and consider a slightly larger quantity to account for loss or waste. Follow the product label for guidance on mix volume per repair and adjust for substrate conditions.
