Description

UC 260 is a twin pack pourable or gunable polyurethane compound designed to be used as a joint filler in floors where movement is limited. Due to its high compressive properties, it helps to reinforce the joint arises against the effect of wheeled traffic. It exhibits good resistance to cleaning solutions, mild acids, alkalis, and oils.

Product Application

As reinforcing joint filler for low movement joints in floors designed to handle heavy wheeled traffic.

In new floors, installation should only commence after a minimum of 28 days of curing.

NB. before shrinkage of the concrete has ceased or temperatures have stabilised, the use of a temporary sealant is highly recommended.

Surface Preparation

All surfaces must be clean, sound, and dry. Remove all loose material and ensure that there is no contamination from oils, greases, curing compounds etc.

Blast clean steel surfaces to at least SA 2.5 and apply a coat of a suitable anticorrosive primer. Joint faces must be parallel

Mixing

Mix the two components together using a slow speed electric drill.

Scrape down the sides of the container during mixing and if required, remix in a second container.

Mix for a minimum of 3 minutes.

Use immediately as the product has a limited pot-life.

Application

The joint depth should be a minimum of 50mm.

The depth of the joint should be controlled by using a compacted layer of dry 5mm silica sand and the joint is then filled with the thoroughly blended UC 260 to the full depth of the joint by either pouring or gunning using a long barrel gun.

As a flush finish is required overfill with the compound to create a raised surface Check an hour or so after the original application to ensure that some of the jointing material has not seeped away and top up as required.

The excess material should be shaved or ground flush the next day.

Staining of the areas adjacent to the joint can occur and should be allowed for.

Important – The sealant MUST be supported from below. • No priming is required.

Cleaning

Clean all tools and equipment with UC 901 before setting of the sealant has taken place.

Safety

Contact with skin should be avoided by wearing gloves and protective clothing.

In case of eye contact wash well and obtain medical advice.
