Introduction Frost heave is when the soil pushes up under a slab as water freezes and expands. You’ll notice uneven edges, cracks, or a section that lifts after cold spells. This is a hands-on issue you can spot by watching how the ground around the foundation sits through freezing and thawing cycles. Moisture in the […]

Introduction An infrared thermometer measures surface temperature without touching the concrete. Use it to spot cold spots, thawing edges, or rapid surface changes during curing, but it won’t reveal internal conditions. Check the device emissivity settings and read the manufacturer instructions for how to use it on concrete. For winter pours, take quick surface readings

Introduction White haze on concrete sealers is a cloudy residue that forms on the surface after sealing. It’s usually caused by moisture pulling minerals to the surface as the sealer cures. In DIY terms, think of it as a salt bloom that can appear on fresh or older coatings. Removal methods vary from gentle wiping

Introduction Concrete sand is the coarse, well-graded sand used in concrete mixes and as bedding material. Mason sand, concrete sand, and play sand differ mainly in texture, particle size, and how they compact. Knowing which to use depends on the job and what the sand needs to do in the mix or base. Mason sand

Introduction Fiberglass mesh and metal lath are both used to reinforce thin cement coats. Fiberglass mesh is lightweight and easy to handle, while metal lath provides more rigid support for tougher jobs. Check manufacturer instructions and local rules to confirm suitability for your project, and look for guidance on compatible mixes and application methods. For

Introduction Alkali–carbonate reaction is a chemical reaction in concrete that happens when alkalis in cement react with carbonate rock in the aggregate. It can cause slow cracking and changes in stiffness over time. This article explains what to watch for and how you might address it in a DIY setting. ACR differs from ASR in

Introduction Crystalline waterproofing is a treatment that makes concrete itself less permeable by filling its pores with crystalline compounds. It is typically applied or incorporated during construction, so the concrete blocks water intrusion rather than just coating it. This approach aims to create internal barriers that work as the concrete hydrates and cures. The mechanism

Introduction Repairing EIFS impact damage means rebuilding the base coat, reapplying the reinforcing mesh, and matching the textured finish so the patch looks and performs like the existing wall. This is a hands-on job that focuses on cleanup, solid bonding of the base coat, correct embedding of mesh, and careful texture and color matching. Check

Introduction Reinforcement can reduce cracking and visible lines at a plaster transition, but it cannot make two moving or failing substrates behave as one. First identify the junction: a gypsum-board joint, masonry-to-gypsum transition, timber-to-masonry junction, or exterior cement-render detail. Then use the tape, mesh, lath, bead, or movement-joint detail specified for that assembly. To keep

Introduction You can plaster over painted masonry only when the existing paint, the masonry behind it, and the exact plaster system are all suitable. Cleaning alone does not make a weak, chalking, damp, or incompatible coating safe to cover: the new work can bond only as well as the paint and masonry beneath it. Choose
