Crack Filler for Trailer Flooring

Restoration of  wooden trailer floors often requires filling of deep gouges and cracks. Key Crack Filler is formulated to handle these tough filling applications and is fully compatible with Floor Restore coatings.

Crack Filler Application Video

Key Crack Filler is applied to trailer flooring with a putty knife. You can immediately over-coat with Key Floor Restore™ or Smooth Move, before Key Crack Filler is fully cured.

Each carton contains three one-quart Crack Filler KEY FP100AB kits.

Stops Cargo Damage from Water Splash-Up 

Crack Filler is the superior remedy for delaminations that “show daylight” and draw in water from wet roadways. Crack Filler repairs stop further damage and deterioration in these spots. Under spray  can no longer penetrate trailer from below. Wash-out water can’t pool and cause rot. Crack Filler can be used alone, but often precedes coating and sealing the entire trailer floor with Key Floor Restore™ , resulting in  a complete restoration and protection. (When a floor with good “slip” is desired use Smooth Move, the special version of Key Floor Restore™ for furniture vans and trailers.)

Crack Filler For Badly Damaged Floors 

When badly damaged trailer floors need sectioning, Crack Filler is ideal for filling the gap between new and old sections. Sealing the section perimeter with tough, Kevlar reinforced Crack Filler will form a tough, impenetrable barrier between the new and old flooring.
