Common Problems and Solutions

Common Problems and Solutions

A successful floor depends on five key issues:

  1. The substrate to which the flooring system is being applied has been laid to a standard building specification.

  2. There is no water or damp ingress.

  3. The site is under the control of the applicator for the full duration of the preparation, application and curing process.

  4. The specified system is laid according to the manufacturer’s specification.

  5. Specific products must be applied by an approved Dekster flooring applicator.

Colour variation visible whilst applying:

CAUSE

Solution

Product ordered in parts and not one batch for the 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

Small pin holes / bubbling appears on the surface:

CAUSE

Solution

No primer used, air entrapment in the 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)

The specified spread rates are not achieved:

CAUSE

Solution

Product too cold (stiff) when applied

Apply in temperatures between 15 – 30 ºC

Incorrect application tools

Check you are using the correct application tools (refer to data sheets)

Applying product too thick

Apply at specified spread rates (refer to data sheets)

Substrates 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:

CAUSE

Solution

Inferior brushes or rollers used

Use specified application tools (refer to data sheets)

Inexperienced applicators

Never rush applying 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

White milky marks appear:

CAUSE

Solution

Substrate contaminated with moisture through rising damp or ingress through walls due to faulty DPC membranes

Incorrect building details

Never lay floors on substrates with a moisture content above 14%

Delamination:

CAUSE

Solution

Weak or faulty substrate

Oil or chemical contamination

Lack of proper preparation

Always inspect floor for hollow spots or oil contamination

Coating does not set (harden):

CAUSE

Solution

Not mixing activator and base

Follow detailed mixing instruction

Not mixing activator and base for specified duration

Follow standard mixing times (refer to datasheets)

Splitting kits

Never part mix or split kits
