The present invention provides a curable composition having an excellent permeability to a porous substrate and a sufficient strength for use as a coating film, and also having a suitable curing time (set time), accordingly the curable composition having a pot life from the application until the completion of the permeation to pore portions. Particularly, the present invention also provides a favorable coating agent for surface reinforcement coating of a porous substrate. These objects can be achieved by using a curable composition containing the following (A) and (B): (A) a cyanoacrylate compound; and (B) a hydrofluoroether having such a structure that the number of carbon atoms substituted only with fluorine in the molecule is 1 or more to 6 or less, and the number of carbon atoms in the molecule is less than 7.

Methods of using a curable composition, the curable composition including at least one polyether having blocked hydroxyl groups as the plasticizer on at least one alkaline substrate. The curable composition is storage-stable, easy to handle and highly elastic after curing, and does not show any tendency to separate or migrate. It enables elastic bonding, sealing or coating of alkaline substrates, such as, in particular, fresh or green concrete or cement mortar, without occurrence of troublesome odors triggered by plasticizer hydrolysis.

The present disclosure provides for an aqueous coating composition to coat and form a film on porous construction materials to help in controlling efflorescence in the porous construction materials. The aqueous coating composition includes a binder having an acrylic polymer in an acrylic polymer waterborne dispersion, wherein the acrylic polymer has a glass transition temperature (Tg) of 1° C. to 60° C.; and an alkoxy silane coalescing agent in a waterborne silane coalescing emulsion. The aqueous coating composition optionally further includes an additive selected from the group consisting of a pigment, a filler and combinations thereof. In one embodiment, the alkoxy silane coalescing agent provides the only coalescing agent for the acrylic polymer waterborne dispersion in the aqueous coating composition.

Polyamine additives are disclosed that are useful to provide early water resistant to drying anionically colloidally stabilized polymer dispersions in aqueous media. The polyamines are polymerization products from ethylenically unsaturated monomers with pendant tertiary amine groups with ethylenically unsaturated monomers with pendant poly(alkylene oxide) chains of 88 to 1200 g/mole molecular weight.

The present disclosure describes modular blocks configured to give the appearance of natural or cut stone. An aesthetic coating composition may be applied to one or more surfaces of a block having a low-density, such as an insulating concrete form (ICF), to form an modular block having the appearance of cut stone. The aesthetic coating composition includes a binder component, such as a cementitious binder made from white Portland cement, or a polymer binder such as an acrylic binder, an aggregate component, such as a limestone aggregate component, and optionally an adhesive component. The aggregate component includes a fine sand portion and a coarse sand portion that effectively enable the appearance of cut stone after finishing of the aesthetic coating surface via sanding, polishing, sandblasting, acid etching, acid finishing, or exposed aggregate finishing.

Post-construction materials, including concrete, containing water insoluble polymers are disclosed herein. The water insoluble polymers are formed beneath the surface of the post-construction material using a first composition comprising a blend of fatty acid salts and a second composition comprising alkaline earth metal halides or alkaline earth metal carbonates.
