Floor Coatings and Sealers
A SUCCESSFUL FLOOR DEPENDS ON FIVE KEY ISSUES:
- The substrate to which the flooring system is being applied has been laid to a standard building specification.
- There is no water or damp ingress.
- The site is under the control of the applicator for the full duration of the preparation, application and curing process.
- The specified system is laid according to the manufacturer’s specification.
- Specific products must be applied by an approved Dekster flooring applicator.
THE SPECIFIED SPREAD RATES ARE NOT ACHIEVED:
|Product too cold (stiff) when applied||Apply in temperatures between 15-30ºC|
|Incorrect application tools||Check you are using the correct application tools (refer to data sheets)|
|Applying product too thick||Apply at specific spread rates (refer to data sheets)|
|Substrate porosity is excessive||Site inspection should alert you to this, notify client and specify in quote that extra primers may be necessary|
BRUSH AND/ OR ROLLER LAP MARKS SHOWING:
|Inferior brushes or rollers used||Use specified application tools (refer to data sheets)|
|Inexperienced applicators||Never rush applying a product, always cut in and roll working as a team and do not allow the applicator cutting in to run ahead of the roller applicators. Rollers must always cross roll and check the applied area has no missed spots before moving on|
COLOUR VARIATION VISIBLE WHILST APPLYING:
|Product ordered in parts and not one batch for entire job||Double check m2 and order correctly|
|Using dirty rollers or brushes and mixing buckets||Clean tools are the sign of an efficient and professional application team|
|Not vacuuming the floor properly before applying sealers especially at the junction of wall and floor||An approved professional flooring applicator will always have a well maintained industrial vacuum cleaner|
WHITE MILKY MARKS APPEAR:
|Substrate contaminated with moisture through rising damp or ingress through walls due to faulty DPC membranes||Never lay floors on substrates with a moisture content above 14%|
|Incorrect building details|
SMALL PIN HOLES/ BUBBLING APPEARS ON THE SURFACE:
|No primer used, air entrapment in small voids move to the surface causing pin holing||Always follow manufacturer’s specification. If substrate is extremely porous, apply 2 primer coats|
|Activator and base mixed too vigorously (high speed festo drill)||Mix on low speed|
|Applied too soon after mixing and not allowing air to move to the surface||Allow mixed product to stand for a few minutes before applying|
|Not using a spike roller when specified||Use specified application tools (refer to data sheets)|
|Weak or faulty substrate||Always inspect floor for hollow spots or oil contamination|
|Oil or chemical contamination|
|Lack of proper preparation|
COATING DOES NOT SET (HARDEN):
|Not mixing activator & base||Follow detailed mixing instructions|
|Not mixing activator and base for specified duration||Follow standard mixing times (refer to data sheets)|
|Splitting kits||Never part mix or split kits|
