Captain Tolley's Creeping Crack Cure may sound like an old fashioned remedy, but it is actually an up-to-date solution to an age old problem: the finding and fixing of mystery leaks without having to take everything apart. It is a one-part water-based acrylic co-polymer penetrating sealant.
The Creeping Crack Cure is so thin that using capillary action it can find its way right inside fine seams and joints to set to a clear flexible seal. It is a totally different approach than most sealants. Being thinner than water, it goes where the water goes. It can find its way right into hairline cracks and hair-thin seams where other sealants cannot reach. It traces mystery leaks. The rapid absorption of the sealant into the seam indicates the potential leak. Even excellent conventional sealants cannot do that. It's quick and easy to apply, too. There's no need to remove old sealants. You just apply the sealant along the line of a crack or joint until no more is absorbed. As an added benefit, its waterbased and non-toxic.
The sealant is safe to use and, unlike other products, it can be applied to cracks even when they are slightly damp. The sealant can be applied safely to most materials, including polystyrene. Note that the exposed edges of the sealant dry first; the sealant in the interior takes longer. Normally a seal is made within 24 hours. The sealant forms a strong flexible bond that can accommodate a small degree of structural movement. When dry the sealant is transparent but it can be painted over successfully as so little of the sealant is exposed to the surface. The sealant is unaffected by sunlight although this does not represent much of a problem as such small areas are exposed. Once cured, the sealant is unaffected by most everyday chemicals.
