Surface Preparation
Joint sides should be clean and dry.
Spalled joints should be repaired initially using Watco Concrex.
For best results use Watco Back Up Rod to reduce deeper joints to the desired depth.
Mixing
It is important that the two components are very thoroughly mixed together.
Poorly mixed product will not cure correctly.
Empty the contents of the smaller tin into the larger tin and mix thoroughly for approximately 3 minutes using a wide bladed tool such as a palette knife. Alternatively use a slow speed electric drill and paddle.
Immediately decant the mixed components into an empty container, ideally a jug (plastic or metal) or can with a pouring spout. This will assist when pouring the product into the floor joint.
Take care to ensure that all the contents are scraped off the sides and bottom of the tins. Mix again for one minute. If a pouring jug is not available, crimp the rim of the empty can to help with pouring.
Application
Pour evenly into the prepared joint, leaving the top of the joint sealant just below the surface of the floor.
If required, finish off with a flat blade or knife to remove air bubbles and then remove any masking tape before the sealant has set, drawing the tape across the sealant face so that any excess sealant falls into the joint and not alongside it.
Watco Floor Joint Sealant will adhere to clean concrete, sand/cement screed, polymer cement, epoxy and other resin toppings and nosings and most other common floor materials.
It will also adhere to steel and other non-porous materials, but Watco’s advice should be sought in the case of plastic materials and bituminous surfaces.
Coverage Rate
Data is approximate and makes allowance for normal wastage, etc.
Coverage rate of primer is up to 100m joint length per 250ml.
Joint Width | 10mm | 15mm | 20mm | 25mm |
Joint Depth | 10mm | 10mm | 10mm | 12.5mm |
2L unit will fill the following length of joint | 18m | 12m | 9m | 5.8m |
Limitations
This is of particular importance in expansion joints to ensure optimum performance.
For joints 5-10mm wide, depth should be equal to width.
For joints 10-20mm wide, depth should be 10mm.
For joints over 20mm wide, depth should be half the width.
