The Complete Guide to Floors and Paint

AMN Construction · Montecito and Santa Barbara South Coast · 17 sections plus local rules, a verify list and 37 sources

Start here

This guide is for AMN Construction crew members, from the first day to master level. It covers floor prep, installing and finishing floors, painting, and the lead, moisture and local rules that go with them. It is written in plain English and every point carries a confidence tag so you know how far to trust it. Research is current as of 2026-11-02.

[S] Sourced a source was read (secondary sources say so) [P] Crew practice common practice, not a published rule [C] Confirm contested, or confirm with the building official or maker [?] Unverified not found or not checked

Read these four flags first

Paint coverage of 350 sq ft per gallon is a rule of thumb (unverified). The can label governs.
41 of the 63 tools are tagged unverified (the research added 30 of them from general trade knowledge). Steps and tips beyond cited numbers are crew practice.
RRP lead-free exclusion text (40 CFR 745.82) was not opened; confirm it with EPA before skipping lead-safe work.
Permit triggers, noise hours, MBAR review of a repaint and County code dates are not confirmed. See “Local rules at a glance”.

The flooring or paint maker’s instructions and the label govern over anything here. The approved plans, the building official and the lead rules override this site. Not engineering or legal advice.

Reading order: sections 1 and 2 first. Then follow your stage on the lesson plan. Math is in the math workbench and every tool is in the tools page.

1. Day 1: Safety, PPE and house rules

Stage: Day 1

[S] SourcedWear eye protection, gloves, hearing protection and a fitted half-face respirator with P100 filters for sanding and scraping [S4][S9] (established)
[P] Crew practice[S] SourcedFacial hair breaks a respirator seal; do a seal check every time [S4] (established: program required; crew practice for the check)
[S] SourcedCal/OSHA lead rules require respirators as interim protection for trigger tasks like manual scraping, heat guns and power sanding [S4] (established)

Tools for this sectionHalf-face respirator with P100 filters Safety glasses and nitrile gloves unverifiedHearing protection unverifiedHEPA vacuum Stepladder unverified

Check yourself

Why can't you blow dust off a surface?

It spreads dust and lead hazards; Cal/OSHA restricts compressed air and dry sweeping; use HEPA vac and damp wipe.

Which filter rating is required for lead filtering facepieces?

N100, R100 or P100.

What do you do if you are unsure how to use a tool?

Ask your lead before starting.

A vendor says 75% RH or less is typical [S7]. A trade article gives 3 lb per 1,000 sq ft per 24 h as a general goal [S36] (no single number; the flooring and adhesive maker sets the limit and the warranty)
[S] Sourced, secondaryASTM F2170: probes at 40% of slab depth (one side drying) or 20% (both sides), 24 h to equilibrate, 3 tests for the first 1,000 sq ft and 1 more per extra 1,000 sq ft; ASTM F1869 takes 60 to 72 h; room at service conditions 48 h before testing [S7][S36] (vendor and trade press; the ASTM text was not opened)

An installer in the same article used 1/4 to 3/8 in as a compromise (contested; the NWFA text itself was not opened, so use the maker sheet for the job)
[S] Sourced, secondaryNailing a 3/4 in solid strip under 3 in wide: 1 to 3 in from each end, then every 8 to 10 in when blind nailing [S20]; a maker sheet says strip every 8 to 10 in, plank every 6 to 8 in, ends 2 to 3 in [S21] (established for strip; plank over 3 in and engineered: use the maker sheet)

What to verify

Everything the research marked contested or unverified, in one place. Treat these as questions for the manufacturer label, the building official or CSLB, not as rules.

Contested

[C] ContestedWhether floors plus paint count as two unrelated trades for a B prime contract: judgment, confirm with CSLB.
[S] SourcedHeat gun limit of 1,100 F: confirmed in 40 CFR 745.85 [S24].
[C] ContestedSlab RH limit of 75%: one vendor figure [S7]; the flooring maker limit governs.
[C] ContestedRespirable silica table (OSHA 3681) applies to concrete grinding; relevance to ordinary wood sanding is not confirmed [S9].
[S] SourcedCal/OSHA 8 CCR 1532.3 (silica in construction): PEL 50 µg/m3 and action level 25 µg/m3 as 8-hour averages; applies to any respirable crystalline silica exposure, so grinding a slab or old cement patch is covered, sanding a wood floor is not [S34] (established)
[S] Sourced[?] UnverifiedCal/OSHA 8 CCR 5155 Table AC-1 lists wood dust (all soft and hard woods except Western red cedar) at 2 mg/m3 PEL with a 5 mg/m3 short-term limit, and Western red cedar at 0.5 mg/m3 [S33] (the copy of the table read was garbled, so confirm the columns on dir.ca.gov)

Unverified or not found

[?] Unverified or not foundManufacturer data point: Benjamin Moore Regal Select matte lists 400 to 450 sq ft per gallon, VOC under 50, dry to touch 1 h, recoat 1 to 2 h [S32]. Sherwin-Williams Duration Home page gave no coverage figure [S37]. Paint coverage of 350 to 400 sq ft per gallon is a rule of thumb. The can label governs.
[?] Unverified or not foundWaste factor of 5 to 15% is crew practice, not a published rule.
[?] Unverified or not foundLVP and laminate are not named in the C-15 text [S1]; structural subfloor repair class C-5 is not confirmed.
[S] SourcedExterior doors and windows within 20 ft must be closed during RRP exterior work, per 40 CFR 745.85(a)(2) [S24].
[?] Unverified or not foundMinimum piece length, and the NWFA text itself for expansion gap and fastener spacing (only trade-press quotes and maker sheets read): take from the flooring maker.
[?] Unverified or not foundA single calcium chloride or RH threshold for wood flooring: none found; limits are set per product by the maker (see sourced items).
[?] Unverified or not foundWhether SBCAPCD Rule 323.1 has been amended since 2015 (district rules page did not list it; phone (805) 961-8800 per ourair.org); CARB 2019 SCM category limits and the 2025 CALGreen Part 11 mandatory table not opened.
[?] Unverified or not foundCALGreen flooring content, County adoption date of the 2025 codes, County permit triggers for painting and floor covering, noise hours: not found.
[?] Unverified or not foundRRP and Cal/OSHA penalty amounts: not found.
